Regulatory signs in the K53 learners test
By The PassPath Team · Updated
Regulatory signs regulate and control what road users do. They either prohibit something or command it. Failing to obey a regulatory sign is an offence, punishable by a fine or imprisonment or both. This is the group where a sign is not advice. Road signs are 28 of the 64 questions in the K53 learners test and you may get five of them wrong, which makes this the group it costs the most to guess at.
Every drawing here was made for PassPath from the prescribed design and is named from the manual’s own legend. Sources last re-checked on . For Code 2 (car) learners. Motorbike (Code 1) and heavy vehicle (Code 3) aren't covered yet.
This page shows 60 drawings of regulatory signs, covering 53 of the 157 regulatory sign codes the Manual on Road Traffic Signs gives a page of its own to. Which signs the test draws from is not published, and we do not claim this is the examinable set.
Working through the pictures is worth more once you have tried the questions. Every sign below is one you can meet in the free K53 practice test.
The three exceptions to the round regulatory shape
Regulatory signs are ordinarily round, but the manual names exactly three exceptions to that shape (Manual Part 2, Sec 1, p.2): the **octagonal stop sign**, the **triangular yield sign**, and the **diamond-shaped pedestrian priority signs**.
These three shapes are not used anywhere else in the regulatory group, so shape alone identifies a stop sign, a yield sign or a pedestrian-priority sign even where colour or wording cannot be read clearly: for example at a distance, in poor light, or on a faded or dirty sign. This is why the manual singles these three out by name rather than leaving them to be inferred from the general 'regulatory signs are round' rule.
- Octagon = stop sign (R1 family).
- Triangle (point down) = yield sign (R2 family).
- Diamond = pedestrian priority sign (R5).
- These are the only three shape exceptions the manual lists for the regulatory group; every other regulatory sign is round.
STOPR1R1 STOP sign. A red octagon with a white border and the word STOP across the middle in white capital letters. No symbol. Easy to get wrong. Warning signs are triangular, not eight-sided. This sign belongs to the regulatory group.
YIELDR2R2 YIELD sign. A downward-pointing triangle standing on its point, with a thin white outer border, a thick red inner border and a white centre. No symbol and no lettering: the shape carries the whole message. Easy to get wrong. A complete stop every time is what a stop sign requires. Here you slow down and stop only if traffic makes it necessary.
PEDESTRIAN PRIORITYR5Red diamond sign with a white border showing a white walking pedestrian: PEDESTRIAN PRIORITY. Easy to get wrong. A crossing ahead is shown by a different, triangular warning sign. This one is a regulatory sign giving pedestrians priority.

Control signs: the stop-sign family (R1.1-R1.5)
Control signs are the first of the regulatory sign types the manual describes (Manual Part 2, Sec 3.1, p.4); they control the order in which road users may proceed. The stop-sign family covers five related signs.
**Stop sign (R1.1)**: found at intersections, railway crossings and scholar patrols; brings traffic to a stop. Bring your vehicle to a stop behind the stop line; if there is no stop line, the front of the vehicle must come to a standstill in line with the sign. At a three- or four-way stop, you may not move off before all vehicles that stopped before you have moved off. Proceed only when it is safe.
**Stop/yield sign (R1.2)**: at intersections; allows left-turning traffic to proceed without stopping, if it can be done without interfering with cross traffic. If you intend to carry straight on, you must still bring your vehicle to a standstill behind the stop line. When turning left, yield to all traffic close enough to pose a hazard, and proceed only when it is safe.
**3-way stop (R1.3)** and **4-way stop (R1.4)**: at intersections; bring traffic from three or four directions to a stop. The two signs are visually near-identical, distinguished by the numeral (3 or 4) on the plate beneath the octagon. Both apply the same rule: if more than one vehicle stops at the intersection, the vehicle that stopped first should move off first. For the 4-way stop specifically, the manual repeats the R1.1 procedure: stop behind the stop line (or in line with the sign if there is no line), then proceed only when safe.
**STOP/RY-GO sign (R1.5)**: usually at road works, for temporary traffic control; two different sign faces mounted back to back, indicating whether you may proceed or must stop. Stop if the STOP face is displayed; move off, or proceed with caution, only when the GO face is displayed and it is safe.
- R1.1 stop: full stop behind the stop line (or level with the sign if no line); proceed only when safe.
- R1.2 stop/yield: straight-ahead/right-turning traffic must still stop fully; left-turning traffic may proceed without stopping if it yields to any traffic close enough to be a hazard.
- R1.3/R1.4 (3-way/4-way stop): identical rule; whichever vehicle stopped first moves off first; distinguished only by the numeral (3 or 4) on the plate below the octagon.
- R1.5 STOP/RY-GO: two faces on one paddle, used at road works; stop on STOP, proceed with caution on GO.
STOP (450 mm)R1.1R1.1 STOP sign, 450 mm. A small red octagon with a white border and the word STOP across the middle in white capital letters. Easy to get wrong. This describes the action for a yield sign (R2), not a stop sign. A stop sign requires a full stop every time, regardless of approaching traffic.
STOP/YIELDR1.2R1.2 STOP/YIELD sign. A red octagon with a white border and the word STOP across the middle in white capital letters, above a separate red-bordered triangle pointing downwards with a white background and a black arrow inside it that rises and then turns to the left. Easy to get wrong. The sign does not give you right of way. You must still yield to traffic close enough to be a danger.
3 WAY-STOP (all-way STOP)R1.3R1.3 3 WAY-STOP sign. A red octagon with a white border and the word STOP across the middle in white capital letters, with a red square plate directly below it carrying a white border and the white numeral 3. Easy to get wrong. Moving off together defeats the purpose of a stop sign, which lets vehicles go one at a time in the order they stopped.
4 WAY-STOP (all-way STOP)R1.4R1.4 4 WAY-STOP sign. A red octagon with a white border and the word STOP across the middle in white capital letters, with a red square plate directly below it carrying a white border and the white numeral 4. Easy to get wrong. Every approach to this sign must stop, including the traffic coming from your right.
GOR1.5BR1.5B GO sign. A yellow octagon with a black border and the word GO across the middle in black capital letters. Easy to get wrong. No separate hand signal is needed once this face is shown. That is the whole point of the sign.

Control signs: the yield-sign family (R2, R2.1, R2.2)
**Yield sign (R2)**: at intersections and railway crossings; indicates you must yield to other traffic. If other traffic is approaching the intersection, reduce speed and, if necessary, stop (Manual Part 2, Sec 3.1, p.4). Unlike the stop sign, a full stop is not automatically required: only if it turns out to be necessary once you assess the approaching traffic.
**Yield to pedestrians (R2.1)**: at intersections and pedestrian crossings; compels the driver to give priority to pedestrians crossing, or wanting to cross, the road. Look out for pedestrians crossing or near the road and be ready to stop (p.5).
**Yield at traffic circle (R2.2)**: at traffic circles, particularly mini circles; warns that a traffic circle lies ahead where the driver must expect to yield. Look out for other vehicles and yield to vehicles already in the circle, or that will cross the yield line at their entrance before you cross yours; stop if necessary. The driver who reaches their own yield line first may proceed first. At a mini circle, signal in good time, exactly as at a normal intersection, to show which direction you intend to turn (p.5).
- R2 yield: reduce speed on approach and stop only if necessary, not an automatic full stop like R1.
- R2.1 yield to pedestrians: give priority to pedestrians crossing or wanting to cross; be ready to stop.
- R2.2 yield at traffic circle: yield to vehicles already in the circle or reaching their yield line first; whoever reaches their own yield line first may go first.
- At a mini traffic circle, signal your intended direction in good time, just as at an ordinary intersection.
YIELDR2R2 YIELD sign. A downward-pointing triangle standing on its point, with a thin white outer border, a thick red inner border and a white centre. No symbol and no lettering: the shape carries the whole message. Easy to get wrong. A complete stop every time is what a stop sign requires. Here you slow down and stop only if traffic makes it necessary.
YIELD TO PEDESTRIANSR2.1Triangular YIELD sign on point above a red rectangular plate with a white border showing a white walking pedestrian: YIELD TO PEDESTRIANS. Easy to get wrong. Neither sign's application depends on time of day; that distinction belongs to selective-restriction plates such as R511/R512, not to R2.1 or R2.2.
YIELD AT TRAFFIC CIRCLER2.2Triangular sign on point with a white border and a red inner border, showing three black arrows circling clockwise: YIELD AT TRAFFIC CIRCLE. Easy to get wrong. Giving way to the right is the rule where nothing controls the junction. Here the sign governs instead.
Source: Manual Part 2, Sec 3.1 (Control Signs, pp.4-5).
Control signs: no entry (R3) and one-way roadway (R4.1-R4.3)
**No entry (R3)**: usually found at the end of a one-way street, at the end of an off-ramp, or at an intersection where a two-way road changes to one-way; indicates that no traffic may proceed past the sign on the road, carriageway or lane. Do not enter the carriageway where this sign is displayed (Manual Part 2, Sec 3.1, p.5).
**One-way roadway (R4.1, R4.2 and R4.3)**: displayed at intersections where a one-way road joins another road; indicates that there is a one-way carriageway to the left, right, or straight ahead (the arrow shows which). Proceed in the direction of the arrow only if you want to use that specific carriageway (p.5).
Both R3 and R4 are Control signs in the manual's own classification (Sec 3.1), not Prohibition signs. This matters because a driver's instinct may be to file 'no entry' alongside the Prohibition group's speed/turn/parking restrictions; the manual instead groups it with the other signs that control the order and direction in which traffic may proceed through a junction (stop, yield, one-way), reflecting that R3 is about which carriageway may be entered at all, not a restriction on an action within a carriageway already being used lawfully.
- R3 no entry: do not enter the carriageway/lane the sign marks; typical sites are one-way-street exits, off-ramp ends, and two-way-to-one-way transitions.
- R4.1/R4.2/R4.3 one-way roadway: the arrow (left/right/straight) shows the one-way direction; only proceed that way if you want that carriageway.
- R3 and R4 are classified as Control signs (Sec 3.1), the same family as stop and yield, not Prohibition signs, despite 'no entry' sounding like a prohibition.
NO ENTRYR3R3 NO ENTRY sign. A red disc with a thin white border and a single wide horizontal white bar across the middle. No other symbol or lettering. Easy to get wrong. R3 prohibits all vehicular traffic (not pedestrians/cyclists specifically), and R211 likewise binds the driver of any vehicle.
ONE-WAY ROADWAY (LEFT)R4.1Red rectangular sign with a rounded white border and a large white left-pointing arrow. Easy to get wrong. The sign sets the direction of ordinary travel along the road. It is not a U-turn instruction.
ONE-WAY ROADWAY (RIGHT)R4.2Red rectangular sign with a rounded white border and a large white right-pointing arrow. Easy to get wrong. Travelling the other way is exactly what the sign prohibits: the roadway runs one way only.
ONE-WAY ROADWAY (UP)R4.3Red rectangular sign with a rounded white border and a large white upward-pointing arrow. Easy to get wrong. The road is not closed to you. The sign tells joining traffic which single direction of travel is lawful.

Control signs: pedestrian priority (R5) and yield to oncoming traffic (R6)
**Pedestrian priority (R5)**: at the entrance to an area intended for pedestrians; gives priority to pedestrians but limits other traffic to emergency vehicles, vehicles loading and off-loading goods, and maintenance vehicles. A driver of one of those permitted vehicles must drive carefully in the area at a maximum speed of **15 km/h**. Priority must be given to pedestrians crossing or wanting to cross the road. When loading or off-loading goods, this may only be done in areas marked by road traffic signs: no other vehicles are permitted in such an area (Manual Part 2, Sec 3.1, p.5).
**Yield to oncoming traffic (R6)**: at the entrance to any road intended for dual-way traffic; indicates a single carriageway ahead for use by vehicles from both directions (a narrowed section where only one direction of traffic can pass at a time). Look out for other vehicles and yield to vehicles already in the carriageway (p.5).
- R5 pedestrian priority: only emergency vehicles, loading/off-loading vehicles and maintenance vehicles may enter; maximum speed 15 km/h; pedestrians always have priority.
- R5: loading/off-loading only in areas marked by road traffic signs; no other vehicle may be in the area.
- R6 yield to oncoming traffic: a single (narrowed) carriageway used by both directions; yield to any vehicle already in the carriageway.
PEDESTRIAN PRIORITYR5Red diamond sign with a white border showing a white walking pedestrian: PEDESTRIAN PRIORITY. Easy to get wrong. A crossing ahead is shown by a different, triangular warning sign. This one is a regulatory sign giving pedestrians priority.
YIELD TO ONCOMING TRAFFICR6R6 YIELD TO ONCOMING TRAFFIC sign. A white disc with a thick red ring border. Inside are two vertical arrows side by side: on the left a narrower red arrow pointing up, and on the right a wider black arrow pointing down that is half again as thick and one and a half times as long. Easy to get wrong. This is not a railway sign. It governs road vehicles where the roadway narrows.

Command signs: minimum speed (R101) and keep left/right (R103, R104)
Command signs are the second regulatory sign type (Manual Part 2, Sec 3.2, p.6): where a control sign governs the order in which traffic may proceed, a command sign instructs the driver to perform a specific action, a minimum speed to keep, a side to pass an obstruction on, or a direction to travel in.
**Minimum speed sign (R101, temporary TR101)**: displayed on any road where slow-moving vehicles could disrupt the traffic flow; regulates the minimum speed of traffic. Do not drive slower than the speed indicated, in km/h.
**Keep left (R103) / keep right (R104)**: displayed at obstructions such as traffic islands; only one of the two is displayed at a time. Pass to the left or right of the obstruction, as indicated by the sign.
An e-toll signage note: since 9 October 2013, five sign items were added to Schedule 1 of the Regulations that post-date this 2012 manual and are not described anywhere in it, including **R132.2 (Pay e-toll)**, a command sign directing a driver entering an e-road that toll payment is required. The manual's command-sign list above predates that amendment and does not mention it; this content follows current law by flagging the gap rather than teaching R132.2's appearance, since no manual or SARTSM text for it has been archived and no sign asset for it exists yet in this library (delta-register entry `post-2012-signage-additions-etoll`).
- Command signs instruct a specific action (contrast: control signs govern right-of-way order; prohibition signs forbid an action).
- R101/TR101 minimum speed: do not drive slower than the indicated speed.
- R103 keep left / R104 keep right: pass to the indicated side of an obstruction (e.g. a traffic island); only one sign shown at a time.
- Flag: R132.2 'Pay e-toll' was added to Schedule 1 on 9 Oct 2013 (GNR.758), after this 2012 manual, so it is current law but has no manual description or sign asset in this library yet.
MINIMUM SPEED 50R101R101 MINIMUM SPEED sign set to 50. A blue disc with a white ring around the edge and the white numerals 50 filling the middle. No other symbol. In the manual. The manual tells sign installers to check this one against R201 and TR201. SA Road Traffic Signs Manual, section 2.3.1.

Command signs: proceed-only (R105-R107), turn-only (R108-R109) and roundabout (R137)
**Proceed left only (R105), proceed right only (R106), proceed straight only (R107)**: displayed at intersections; indicate the direction in which the driver must proceed. Drive only in the direction indicated by the arrow (Manual Part 2, Sec 3.2, p.6). Temporary equivalents TR105/TR106/TR107 use the same yellow/temporary-colour convention as any other temporary sign.
**Turn left only (R108), turn right only (R109)**: also at intersections; indicate the direction in which the driver must turn at the intersection ahead. Proceed only in the direction indicated by the arrow (p.6).
The proceed-only and turn-only signs look alike (a blue disc with a white arrow) and share the same 'only this direction' logic, but they are not interchangeable in what they compel: a proceed-only sign (R105-R107) can include 'proceed straight' as one of its three options, while the turn-only signs (R108-R109) apply specifically to the turn a driver must make at the intersection ahead, with no straight-ahead form in this pair.
**Roundabout (R137, temporary TR137)**: displayed on any road with multiple intersecting roads; indicates that the driver must move in a clockwise direction at the junction. Yield right of way to any vehicle approaching from the right within the roundabout where it is close enough to cause a danger or potential danger, then proceed clockwise if it is safe to do so (p.10).
Beyond the direction and turn arrows, Sec 3.2 also lists a large run of 'road/lane reserved for [class of road user] only' command signs (R110 pedestrians only, R111 cyclists only, R116 motorcycles only, R117 motor cars only, and most further numbered signs up to R136 for taxis, minibuses, midibuses, buses, delivery/goods/construction/dangerous-substances/abnormal vehicles, rickshaws, tour buses, agricultural and animal-drawn vehicles): each of those works the same way: the class of vehicle named may use the marked road or lane, and no other vehicle may. Two numbers in the same run break that pattern and are not reservation signs at all: R132 (pay toll, weigh an alternative route against paying to proceed) and R133 (switch headlamps on, in the dip position, before a tunnel or in mountainous areas). This family is noted here as a pattern rather than sign-by-sign, since the individual class-restriction signs are not separately covered by this QC's cited pages beyond the general principle.
- R105/R106/R107 proceed left/right/straight only: drive only in the arrow's direction.
- R108/R109 turn left/turn right only: turn only in the arrow's direction at the intersection ahead; no 'proceed straight only' equivalent in this pair.
- R137 roundabout: move clockwise; yield to vehicles already in the circle approaching from the right if they are close enough to be a hazard.
- R110-R136 are mostly a family of 'road/lane for [named class of road user] only' command signs (pedestrians, cyclists, motorcycles, motor cars, taxis, buses, etc.): same reserved-use logic, not itemised individually here. R132 (pay toll) and R133 (switch headlamps on) sit in the same numeric run but are not reservation-class signs.

PROCEED LEFT ONLY (temporary)TR105A yellow disc with a black ring set in slightly from the edge and a large black left-pointing arrow across the middle. No other symbol. Easy to get wrong. A temporary sign shows that normal conditions have changed. It must be obeyed with extra care, not ignored.

Prohibition signs: speed, mass, axle-mass, height and length limits
Prohibition signs are the third regulatory sign type (Manual Part 2, Sec 3.3, p.11); where a command sign instructs an action, a prohibition sign forbids one.
**Speed limit (R201, temporary TR201)**: on any public road; informs the driver of the speed limit that applies, from the sign onward. Do not exceed the speed indicated.
**Mass limit (R202, TR202)**: on any public road; prevents certain heavy vehicles from using a road or part of a road. If your vehicle's Gross Vehicle Mass (GVM) or Gross Combination Mass (GCM) exceeds the indicated mass in tons, use another road or part of the road not covered by the sign.
**Axle mass limit (R203, TR203)**: on any public road; prohibits certain heavy vehicles from using the road. If the mass on any of your vehicle's axles exceeds the indicated mass in tons, use another road or part not covered by the sign.
**Height limit (R204, TR204)**: on any public road; warns of a height restriction ahead. If your vehicle (or its load) is higher than the indicated height in metres, an alternative road not covered by the sign must be used.
**Length limit (R205, TR205)**: on any public road, especially mountainous areas; prohibits long vehicles from using a road where such a vehicle could not negotiate a curve, or would have to manoeuvre in a way that disrupts or endangers other traffic. Take an alternative route if applicable.
Across this group, note the recurring pattern in the manual's own wording: the driver's own vehicle characteristics (mass, axle load, height, length) are compared against the number on the sign, and if the vehicle exceeds it, the driver must use a different route; the sign does not apply to a vehicle within the stated limit.
- Prohibition signs forbid a specific action (contrast: command signs instruct one; control signs govern order of proceeding).
- R201/TR201 speed limit: do not exceed the indicated speed, applying from the sign onward.
- R202 mass limit / R203-TR203 axle mass limit: heavy vehicles exceeding the indicated tonnage must use a different road.
- R204 height limit / R205 length limit: vehicles (or loads) exceeding the indicated height, or long vehicles that cannot safely negotiate the road, must use an alternative route.
SPEED LIMIT 80R201R201 SPEED LIMIT sign set to 80. A white disc with a wide red ring around the edge and the black numerals 80 filling the middle. No other symbol. In the manual. The manual tells sign installers to check this one against TR201. SA Road Traffic Signs Manual, section 2.3.1.

Inside, in black: the numeral 2 beside a lower-case t across the top, a short arrow pointing straight down below them, and at the bottom an axle drawn as two wheels joined by a bar. No diagonal line. Easy to get wrong. Total vehicle mass is controlled by a different sign. This one measures the load carried on one axle.

Prohibition signs: turn-ahead, no-left/right-turn, U-turn and overtaking
**Left turn ahead prohibited (R209, TR209) / right turn ahead prohibited (R210, TR210)**: on any public road before a junction; prohibits vehicles from turning at the intersection ahead. Do not turn left or right at that intersection, depending on the sign displayed (Manual Part 2, Sec 3.3, p.12).
**Left turn prohibited (R211, TR211) / right turn prohibited (R212, TR212)**: at intersections on any public road; prohibits turning left or right at that intersection. Where a left-turn prohibition is displayed, you may proceed straight or turn right. Where a right-turn prohibition is displayed, you may proceed straight or turn left (p.12): in both cases, the sign removes only the one turn it names, not straight-ahead travel or the opposite turn.
**U-turn prohibited (R213)**: on a public road before, or on the far side of, an intersection; prohibits a driver from turning the vehicle around to face the opposite direction. Do not turn your vehicle around so that it faces the opposite direction (p.12).
**Overtaking prohibited (R214, TR214, R215, TR215)**: on any public road; informs drivers that overtaking is prohibited for the next 500 m. If R214/TR214 is displayed, do not overtake any vehicle for the next 500 m. If you are driving a heavy motor vehicle and R215 is displayed, do not overtake another heavy vehicle (p.12).
- R209/R210 (turn ahead prohibited): no left/right turn at the intersection the sign warns of.
- R211 (no left turn) / R212 (no right turn): at the intersection itself; the sign removes only the named turn; straight ahead and the other turn remain open.
- R213 U-turn prohibited: do not turn the vehicle to face the opposite direction.
- R214/TR214 overtaking prohibited: no overtaking for the next 500 m. R215 is the heavy-vehicle-specific version: no heavy vehicle may overtake another heavy vehicle.

Prohibition signs: no parking (R216) and no stopping (R217)
**Parking prohibited (R216, TR216)**: displayed on a public road where the road is narrow, near an intersection, or where a parked vehicle could impair the vision of other drivers; prohibits drivers from parking during any time of the day or night. Do not park where these signs are displayed (Manual Part 2, Sec 3.3, p.12).
**Stopping prohibited (R217, TR217)**: on any public road; the sign may be supplemented by a red 'no stopping line'. Its purpose is to ensure traffic flow and prevent a driver's view being impaired by stationary vehicles. Do not stop, unless to obey a traffic light or a traffic officer, or to avoid a collision (p.12).
R217 (no stopping) is the stricter of the two: it forbids the vehicle coming to rest at all, with only the three named exceptions (traffic light, traffic officer, avoiding a collision). R216 (no parking) is narrower: it forbids parking specifically, which leaves room for a brief, attended stop (for example, to drop off a passenger) that would not count as 'parking' in the way the sign restricts.
- R216 no parking: do not park (day or night) where the sign is displayed, sited at narrow roads, near intersections, or where a parked vehicle would block other drivers' view.
- R217 no stopping: do not stop at all, except to obey a traffic light/officer or to avoid a collision; may be supplemented by a red no-stopping line.
- R217 is stricter than R216: 'no stopping' forbids coming to rest for any reason outside the three named exceptions; 'no parking' targets parking specifically.
Parking prohibited signR216R216 Parking prohibited sign. A round plate with a wide red border and a white face. One mark in black and red over about a quarter of the face. It is not the same left and right: the ink with no mirror on the other side lies to the left. The marks run up to the right. Easy to get wrong. Stopping is prohibited by a different sign, which keeps traffic flowing. This one prohibits parking.
Stopping prohibited signR217R217 Stopping prohibited sign. A round plate with a wide red border and a white face. One mark in black and red over about a quarter of the face. It is not the same left and right: the ink with no mirror on the other side lies to the right. Easy to get wrong. That is what the no-parking sign means; this one goes further and stops you from pulling up at all.

Distinguishing commonly confused regulatory signs
A handful of regulatory-sign pairs are easy to confuse at a glance or in a rushed answer, but each imposes a different obligation.
**Stop (R1.1) vs yield (R2).** Both are control signs found at intersections, and both are shape-exceptions to the round regulatory norm, but the obligation differs: stop always requires bringing the vehicle to a complete standstill behind the stop line (or level with the sign) before proceeding when safe; yield requires only reducing speed on approach, stopping only if it turns out to be necessary given the traffic present (Manual Part 2, Sec 3.1, pp.4-5).
**No left turn (R211) vs no right turn (R212).** Both are prohibition signs with an identical layout (a red-ringed white disc with a black diagonal band over a black arrow) distinguished only by which way the arrow (and the diagonal band) points. R211 removes the left turn only (straight and right remain open); R212 removes the right turn only (straight and left remain open) (Sec 3.3, p.12).
**Proceed left only (R105) vs proceed right only (R106).** Both are command signs with the same blue-disc-and-white-arrow layout, mirror images of each other; the arrow direction is the only distinguishing feature, and each compels the driver to travel only that way (Sec 3.2, p.6).
**Minimum speed (R101) vs speed limit (R201).** Easy to conflate because both display a number in km/h, but they impose opposite obligations. R101 (a blue command sign) sets a floor: do not drive slower than the number shown. R201 (a white-and-red prohibition sign) sets a ceiling: do not exceed the number shown (Sec 3.2 p.6; Sec 3.3 p.11).
**No parking (R216) vs no stopping (R217).** Both are prohibition signs restricting where a vehicle may come to rest, but R217 (no stopping) is the stricter of the two: it forbids stopping for any reason outside its three named exceptions (traffic light, traffic officer, avoiding a collision), while R216 (no parking) targets parking specifically and does not by itself outlaw every brief, attended stop (Sec 3.3, p.12).
**No entry (R3) vs no left/right turn (R211/R212).** Easy to lump together as 'signs that stop you going somewhere', but R3 is a control sign that forbids entering a carriageway or lane at all (typically the wrong end of a one-way street), while R211/R212 are prohibition signs that forbid one specific turning movement at an intersection while leaving the carriageway itself open to other movements (Sec 3.1 p.5; Sec 3.3 p.12).
- Stop (R1.1) always requires a full stop; yield (R2) requires slowing and stopping only if necessary.
- R211 (no left turn) and R212 (no right turn) are mirror-image signs: read the arrow/band direction, not just 'there's a prohibition here'.
- R105 (proceed left only) and R106 (proceed right only) are mirror-image command signs: same check.
- R101 (minimum speed) sets a floor; R201 (speed limit) sets a ceiling: opposite obligations despite both showing a km/h number.
- R217 (no stopping) is stricter than R216 (no parking): no stopping forbids resting for any non-exempt reason; no parking targets parking specifically.
- R3 (no entry) blocks entering the carriageway/lane entirely; R211/R212 block only one specific turn, leaving the carriageway open to other movements.
STOPR1R1 STOP sign. A red octagon with a white border and the word STOP across the middle in white capital letters. No symbol. Easy to get wrong. Warning signs are triangular, not eight-sided. This sign belongs to the regulatory group.
YIELDR2R2 YIELD sign. A downward-pointing triangle standing on its point, with a thin white outer border, a thick red inner border and a white centre. No symbol and no lettering: the shape carries the whole message. Easy to get wrong. A complete stop every time is what a stop sign requires. Here you slow down and stop only if traffic makes it necessary.

Reservation signs: the entrance and lane signs (R301-R307)
Reservation signs are the fourth regulatory sign type (Manual Part 2, Sec 3.4, p.17); they reserve a road, lane or parking area for the exclusive use of a specified class of vehicle or road user, and appear at the entrance to the carriageway, lane or area concerned.
**Bus reservation (R301, TR301) and bus parking reservation (R301-P, TR301-P)**: at the entrance to any carriageway, lane or parking area; indicate that the road or part of the carriageway is reserved for buses only, and that only buses may park where R301-P is displayed. Do not enter this area, or park here, if you are not driving a bus.
**Bus lane reservation (R302, TR302) and begin bus lane reservation (R303, TR303)**: on any road, particularly in urban areas. R302/TR302 indicate that no other class of vehicle may use that part of the road; R303/TR303 mark the point where the reserved bus lane starts. Do not follow this bus route if you are not driving a bus.
**Pedal cycle lane reservation (R304, TR304) and pedal cycle parking reservation (R304-P, TR304-P)**: at the entrance to, or inside, a demarcated area; the parking version reserves a parking area for bicycles only. If you are not riding a bicycle, do not enter or use this area.
**Parking reservation (R305-P, TR305-P) and limited parking reservation (R306-P, TR306-P)**: on any road or other area where parking bays are demarcated, but the two impose different conditions rather than reserving the bay for a vehicle class: R305-P marks a parking area for vehicles with a Gross Vehicle Mass under 3 500 kg where no time limit applies but a fee must be paid; R306-P marks a parking area that may be used free of charge or at a fee, with the maximum permitted parking time displayed on the sign. Park in accordance with the sign and any road markings; pay the tariff if required and do not overstay the indicated time.
**Motorcycle reservation (R307, TR307) and motorcycle parking reservation (R307-P, TR307-P)**: on any road or at the entrance to a parking area; reserve a portion of the road, or a parking area, for motorcycles only. Do not use the road or the parking area if you are not riding a motorcycle.
Most of this group follows one pattern (a road, lane or parking area is reserved for the named class of vehicle or road user, and no other class may enter it) but R305-P and R306-P are the exception: they regulate parking by fee and time, not by vehicle class, so any vehicle may use them subject to those conditions.
- Reservation signs (Sec 3.4) reserve a road, lane or parking area for a specified class of vehicle or road user, shown at the entrance to the area concerned.
- R301/R301-P (bus), R302/R303 (bus lane / where it begins), R304/R304-P (pedal cycle), R307/R307-P (motorcycle): do not enter/use/park if you are not driving or riding the named class.
- R305-P (fee, no time limit, GVM under 3 500 kg) and R306-P (free or fee, time-limited) are parking-condition signs, not vehicle-class reservations: any vehicle may use them subject to the fee/time rule shown.

Reservation signs: the p.18 vehicle classes (R308-R315)
The manual continues Sec 3.4 with a long run of paired reservation signs (one 'vehicle reservation' sign and one matching '-P' parking-reservation sign for each class) introduced with a single instruction that applies to the whole run: 'the following road traffic signs require the same action from a driver, but the areas concerned are reserved for the vehicle depicted on sign' (p.18). If you are not driving or riding a vehicle of the class shown, do not use the reserved road/lane, and do not park in the matching reserved parking area.
The classes covered on p.18 begin with: motor car (R308, TR308, R308-P, TR308-P), taxi (R309, TR309, R309-P, TR309-P), minibus (R310, R310-P, TR310, TR310-P), midibus (R311, R311-P, TR311, TR311-P), delivery vehicle (R312, R312-P, TR312, TR312-P), goods vehicle (R313, TR313, R313-P, TR313-P), goods vehicles over the indicated Gross Vehicle Mass (R314, TR314, R314-P, TR314-P), and construction vehicle (R315, TR315, R315-P, TR315-P).
- R308-R324 pair a vehicle-class reservation sign with a matching '-P' parking-reservation sign, one pair per class (motor car, taxi, minibus, midibus, delivery, goods, goods over GVM, construction, hazardous substances, abnormal, rickshaw, tour bus, HOV, ambulance, disabled persons, authorised vehicle).
- The rule is uniform across the whole run: if you are not driving/riding the named class, do not use the reserved road/lane or park in the matching reserved area.

Reservation signs: the special-use and authorised classes (R316-R324)
The same p.18 run continues with vehicles conveying hazardous substances (R316, TR316, R316-P, TR316-P), abnormal vehicle (R317, TR317, R317-P, TR317-P), rickshaw (R318, TR318, R318-P, TR318-P), tour bus (R319, TR319, R319-P, TR319-P), and high occupancy vehicle (R320, TR320, R320-P, TR320-P).
The pattern carries onto p.19 with ambulance/emergency vehicle (R321, TR321, R321-P, TR321-P), disabled persons vehicle (R323, TR323, R323-P, TR323-P), and authorised vehicle, for example the diplomatic corps, (R324, TR324, R324-P, TR324-P). Every one of them carries the same instruction the run opened with: if the vehicle depicted is not the one you are driving, the reserved road, lane or parking area is not yours to use.
- The class on the sign changes through this run (hazardous substances R316, abnormal R317, rickshaw R318, tour bus R319, high occupancy R320, emergency R321, disabled persons R323, authorised R324) but the instruction does not: if you are not driving that class, the reserved road, lane or parking bay is not yours to use.

Reservation signs: the combined bus, midibus and minibus lane variants (R327-R335)
The last part of p.19 stops naming single classes and starts combining them, in a set of variants for bus/minibus/midibus operators: bus and minibus reservation (R327, R327-P) with its lane reservation (R328, TR328) and the sign marking where that lane begins (R329, TR329); bus and midibus (R330, TR330, R330-P, TR330-P) with its own lane-reservation (R331, TR331) and lane-begins (R332, TR332) pair; and bus, midibus and minibus together (R333, TR333, R333-P) with its own lane-reservation (R334, TR334) and lane-begins (R335, TR335) pair.
This entire run is one family in substance, not roughly twenty-five separate rules to memorise individually: each vehicle-reservation sign names a class, its '-P' partner reserves parking for that same class, and the lane-reservation/lane-begins pairs (R328/329, R331/332, R334/335) work exactly like the earlier R302/R303 bus-lane pair; one sign marks the reserved lane, the other marks where it starts.
- R327-R335 extend the same logic to combined bus/midibus/minibus classes, each with its own reservation sign and, where relevant, a lane-reservation/lane-begins pair (mirroring R302/R303).

Reservation signs: bus stop reservation and the terminus exception (R325, R326)
**Bus stop reservation (R325, TR325, R325-P, TR325-P) and minibus stop reservation (R326, TR326)**: on any public road; allow a bus or minibus of the organisation named on the sign to take up and drop off passengers. A vehicle using the stop must display an appropriate emblem, logo or other indication that it belongs to that organisation (Manual Part 2, Sec 3.4, p.20).
Both signs draw a sharp distinction the manual repeats for each: a brief stop to take up or drop off passengers is permitted for a matching vehicle, but the driver may only wait with, or park, the vehicle at the sign if the road traffic sign itself indicates that the stop is a **terminus**. A driver of a matching bus or minibus at a stop that is not indicated as a terminus may load or unload and then must move on: waiting or parking there is not permitted regardless of the vehicle's own schedule.
*Source note:* the manual's own Purpose/Action text for R325 names only "minibuses" (identical wording to R326's entry) even though R325's Name field and its regulation number sit in the bus-specific part of the reservation family. SARTSM Vol 1 Ch 2 confirms R325 is the BUS STOP RESERVATION sign and R326 the separate MINIBUS STOP RESERVATION sign; this node follows SARTSM's sign identity for R325 and treats the manual's Purpose/Action wording as a drafting duplication of R326's text, not as evidence R325 covers minibuses only.
- R325/R326 (p.20): a bus/minibus of the named organisation, displaying its emblem or logo, may stop to take up or drop off passengers.
- Waiting or parking at the stop is only permitted if the sign indicates the stop is a terminus: otherwise the vehicle must move on after loading/unloading.
- The manual's own R325 Purpose/Action text says "minibus" (duplicating R326's wording); SARTSM Vol 1 Ch 2 confirms R325 is the bus sign and R326 the separate minibus sign: this node follows SARTSM on sign identity.

Comprehensive signs: freeway begins (R401, R402) and the Woonerf (R403)
Comprehensive signs are the fifth regulatory sign type (Manual Part 2, Sec 3.5, p.20); rather than a single instruction, each applies a whole set of rules to the road or area from the sign onward.
**Dual-carriageway freeway begins (R401)** and **single-carriageway freeway begins (R402)**: at the start of a dual-carriageway or single-carriageway freeway respectively; indicate that a freeway begins at the sign and that all the rules that apply to freeways take effect from there. Follow every freeway rule from this point.
**Woonerf (R403)**: on any public road; combines several rules for the whole street rather than one action. It prohibits entry to any vehicle with a mass exceeding 3 500 kg, or with more than 10 seats, except for local access or delivery; it gives pedestrians right of way in the street; it prohibits vehicles from driving through the area without breaking their journey; and it limits the speed of vehicles in the area to 30 km/h. Drive slowly, obey all four rules, and watch especially for children playing in the street.
R401, R402 and R403 are grouped together because each packages multiple rules into one sign: 'comprehensive' describes the sign doing several jobs at once, not a single prohibition, command or reservation.
- Comprehensive signs (Sec 3.5) apply a set of rules to a whole road/area, not a single instruction.
- R401 (dual-carriageway freeway begins) / R402 (single-carriageway freeway begins): all freeway rules take effect from the sign.
- R403 Woonerf: vehicles over 3 500 kg or with more than 10 seats barred except local access/delivery; pedestrians have right of way; no through-traffic without breaking the journey; speed limited to 30 km/h.

Selective restriction signs: when the main sign applies (R502-R512)
Selective restriction signs are the sixth regulatory sign type (Manual Part 2, Sec 3.6, p.21); a selective restriction sign is a smaller subsidiary sign mounted below a regulatory sign that narrows when or how the regulatory sign above it applies: it does not create a new rule on its own.
**Two-time-periods (R502) and two-time-periods/days (R503)**: displayed below a regulatory sign; indicate that the sign above applies only during the period(s) or conditions shown on the subsidiary sign. Obey the times given.
**Maximum stay during two periods/days (R505, R506)**: below a regulatory sign; limit the times and periods during which a vehicle may stop or park. Do not stop or park longer than the times indicated.
**Reduced visibility (R510)**: below a regulatory sign; informs the driver that the sign above applies specifically when visibility is reduced. Obey the regulatory sign under those conditions.
**Daytime (R511)** and **night time (R512)**: below a regulatory sign; restrict the sign above to daytime only or to night time only, respectively; the two are opposites, not variants of the same rule.
Every sign in this group does the same job: it takes an otherwise unqualified regulatory sign and states the specific window (a time period, a visibility condition, or a time of day) during which that regulatory sign must actually be obeyed.
An e-toll signage note: since 9 October 2013, the same Schedule 1 amendment that added the command sign R132.2 (Manual Part 2, Sec 3.2, see the Command Signs module) also inserted **R536 ('e-Toll Plaza collection ahead')** into this selective-restriction numeric range, displayed below the applicable regulatory sign. This 2012 manual's Sec 3.6 list runs only as far as R540 and does not mention R536; no manual or SARTSM text for it has been archived and no sign asset for it exists in this library yet (delta-register entry `post-2012-signage-additions-etoll`, currently scoped to K53-T2-QC5/QC16: flagging that its qcRefs should also cover this QC, K53-T2-QC10, since R536 sits inside the selective-restriction family this QC covers).
- Selective restriction signs (Sec 3.6) are subsidiary signs below a regulatory sign that narrow WHEN it applies: they don't create a new rule on their own.
- R502/R503: the regulatory sign above applies only during the named time period(s)/day(s). R505/R506: maximum stay/parking duration during named periods.
- R510: the regulatory sign applies specifically when visibility is reduced. R511 (daytime) / R512 (night time): opposite time-of-day restrictions.
- Flag: R536 ('e-Toll Plaza collection ahead') was added to Schedule 1 on 9 Oct 2013 (GNR.758) inside this same selective-restriction numeric range (after this 2012 manual) so it is current law but has no manual description or sign asset in this library yet; delta-register entry post-2012-signage-additions-etoll documents the amendment but does not yet list this QC in its qcRefs.

Selective restriction signs: direction, operator and vehicle-count qualifiers (R520-R540)
**Reserved movement left by vehicle class (R520), reserved movement right by vehicle class (R521), and reserved movement to left and right by vehicle class (R522)**: displayed below a regulatory sign; indicate that the restriction shown on the regulatory sign applies in the direction the arrow points. Obey the primary sign according to the indicated direction (p.21).
**Pay and display (R523)**: below a regulatory sign; indicates that parking fees must be paid in the parking area. Pay the parking fee and display the receipt on or within the vehicle (p.21).
**Operator identity by logo (R530) and by text (R531)**: below the appropriate regulatory sign; indicate that the sign applies to drivers of vehicles operated by the company, owner or organisation shown. If your vehicle belongs to that company or organisation, obey the regulatory sign above (p.22).
**Maximum number of vehicles (R540)**: below the appropriate regulatory sign; indicates that the reservation shown on the regulatory sign is further limited to a maximum number of vehicles. Do not enter an area if doing so would put the number of vehicles present over the number indicated (p.22).
Where the R502/R503/R505/R506/R510/R511/R512 group (covered separately) narrows WHEN a regulatory sign applies, this group narrows WHO it applies to and HOW MANY: a direction (R520-R522), a payment condition (R523), a named operator (R530/R531), or a headcount limit (R540).
- R520 (left) / R521 (right) / R522 (left and right): the regulatory sign's restriction applies in the direction the arrow points.
- R523 pay and display: pay the parking fee and display the receipt on or within the vehicle.
- R530 (logo) / R531 (text) operator identity: the regulatory sign above applies to vehicles of the named company/owner/organisation.
- R540 maximum number of vehicles: do not enter an area if it would put the vehicle count over the number shown.

Combination signs (regulatory) and de-restriction signs (R600)
**Combination signs (regulatory)** are the seventh regulatory sign type (Manual Part 2, Sec 3.7, pp.22-23): a regulatory sign's code and a selective-restriction or other secondary code are joined to produce one combined message, narrower than either code alone. Unlike the other regulatory groups, the manual does not give this section a Name/Where/Purpose/Action entry for each sign: it simply lists example combinations and states, in each case, what the combined codes mean together. A driver reads a combination sign the same way regardless of which two codes are joined: apply the primary regulatory sign's rule, narrowed exactly as the secondary code states.
Representative examples from the manual's own list: **R213-512**: No U-turn, night-time (the R213 U-turn prohibition, narrowed by the R512 night-time selective restriction). **R306-523**: limited parking, pay and display (the R306-P limited-parking reservation, combined with the R523 pay-and-display condition). **R201-511**: speed limit, daytime (the R201 speed limit, narrowed by the R511 daytime restriction). **R217-571**: No stopping, vehicle conveying dangerous goods (the R217 no-stopping prohibition, narrowed to a named vehicle class by a secondary code not separately itemised in Sec 3.6). Some combinations pair two regulatory-family codes, as above; others pair a regulatory code with a differently-numbered secondary or plate code not otherwise itemised in this section: the reading method is unchanged. The manual lists roughly twenty such combinations in total; the pattern is the same throughout: read the primary code's rule, then apply the secondary code's qualification to it.
**De-restriction signs (R600)** are the eighth and final regulatory sign type (Sec 3.8, p.23): they cancel a restriction. From the point where an R600 sign is displayed, the driver no longer has to comply with the restriction sign that carries a symbol similar to the de-restriction sign, but without the sign's red cross: the de-restriction sign itself is the one carrying the red cross over the symbol; the earlier, still-in-force restriction sign does not. The examples the manual gives are not limited to one kind of restriction: **R132-600** and **R133-600** (cancelling the toll and dipped-headlamp command signs), **R202-600** (cancelling a mass limit), **R304-600** (cancelling a pedal-cycle-lane reservation), and **R401-600 / R402-600 / R403-600** (cancelling the freeway-begins and Woonerf comprehensive signs). A de-restriction sign always ends a restriction; it is never itself a new restriction, and it is not a discount or partial relaxation: from the sign onward the earlier rule simply no longer applies.
- Combination signs (Sec 3.7) join a regulatory code with a selective-restriction or other secondary code into one narrower message: read the primary rule, then apply the secondary qualification.
- Examples: R213-512 (no U-turn, night-time), R306-523 (limited parking, pay and display), R201-511 (speed limit, daytime), R217-571 (no stopping, vehicle conveying dangerous goods).
- De-restriction signs (R600, Sec 3.8) cancel an earlier restriction from the point displayed; the R600 sign itself carries the red cross over the restriction's own symbol: the earlier, still-in-force restriction sign lacks that cross.
- R600 examples cover more than speed limits: toll (R132-600), dipped headlamps (R133-600), mass limit (R202-600), pedal-cycle reservation (R304-600), and the freeway/Woonerf comprehensive signs (R401-600, R402-600, R403-600).

Questions people ask about regulatory signs
- What is a regulatory sign?
- A sign that regulates and controls what road users do. It either prohibits something or commands it, which is what separates it from a warning sign that only tells you what is ahead and from a guidance sign that only points you somewhere.
- What shape is a regulatory sign?
- Ordinarily round. The manual names exactly three exceptions: the octagonal stop sign, the triangular yield sign, and the diamond-shaped pedestrian priority signs. No other regulatory sign uses those shapes, so at a distance, in poor light or on a faded sign, the shape alone tells you which of the three you are looking at.
- What happens if you ignore a regulatory sign?
- It is an offence, punishable by a fine or imprisonment or both. The Manual on Road Traffic Signs says so directly, and regulation 285(1) of the National Road Traffic Regulations draws the same line: a regulatory sign directs you to take or not take a specific action, while a guidance or information sign only indicates or informs.
- How many road sign questions are in the K53 learners test?
- 28 of the 64, and you need 23 of them correct. Signs are marked as their own section with their own pass mark, so clearing it does not help you if you miss one of the other two. Government Notice R.93 of 2006, Government Gazette 28446, section 5.4.
- Are these all the regulatory signs?
- No, and we do not claim they are. The manual gives a page of its own to far more regulatory sign codes than this page draws, which of them the test draws from is not published, and the count on this page is stated above the first sign so you can see exactly what you are getting.
Where every fact on this page comes from
Each claim, its source, and how strongly we can stand behind it.
Regulatory signs regulate and control road users by prohibiting or commanding, and they are ordinarily round, with the octagonal stop sign, the triangular yield sign and the diamond-shaped pedestrian priority signs given as exceptions.

What each sign on this page is called, what it looks like, and which signs the manual warns are confused with it.
The names are read from each drawing's own title, which comes from the manual's legend. The confusion notes marked as the manual's own are built from its instruction to sign installers to check a sign against named others, with the section it appears in.
