Question 1Traffic signs, signals and road markings

You approach an octagonal red sign with the word STOP painted in white. What does the law require you to do?

  1. Reduce speed and sound your horn before entering
  2. Slow down and continue if the road looks clear
  3. Bring the vehicle to a complete stop Correct answer.
  4. Stop only when other vehicles are approaching

Explanation

An octagonal red STOP sign requires the vehicle to come to a complete halt at the stop line or, where no line is painted, at the edge of the intersecting road. The halt is required every time, whether or not other traffic is visible, and you may only move off after yielding to vehicles and pedestrians with priority.

Question 2Traffic signs, signals and road markings

You see an inverted triangle with a red border and a white centre at a junction. What does it mean?

  1. No entry for all vehicles
  2. You have priority over traffic approaching from the other road
  3. Stop completely before every entry
  4. Give way to traffic on the road you are joining Correct answer.

Explanation

The inverted triangle is the give-way (yield) sign, placed on the minor road. You must let traffic on the priority road pass before you enter or cross it, and you need stop only when traffic or pedestrians make it necessary.

Question 3Traffic signs, signals and road markings

A single yellow line runs along the centre of a two-way road. What does it indicate?

  1. It marks a lane reserved for buses
  2. It marks the boundary of a pedestrian zone
  3. It divides opposing traffic flows Correct answer.
  4. It marks the edge of a parking bay

Explanation

Yellow centre lines divide traffic travelling in opposite directions, while white lines divide lanes carrying traffic the same way. Knowing which colour you are looking at tells you whether the traffic on the other side of the line is coming towards you.

Question 4Traffic signs, signals and road markings

A steady red traffic light is showing as you approach an intersection. Where must you stop?

  1. Anywhere as long as the engine keeps running
  2. At least 10 metres before the light
  3. After the pedestrian crossing so you can see
  4. Behind the stop line or before the crossing Correct answer.

Explanation

A red light means stop and stay stopped behind the stop line; where no line is painted, stop before the pedestrian crossing or the edge of the intersection. You may proceed only when a green light or a green arrow permits that movement.

Question 5Traffic signs, signals and road markings

Most regulatory signs with a blue circular background give instructions that are:

  1. Advisory suggestions you may ignore
  2. Only for heavy vehicles
  3. Only for pedestrians
  4. Mandatory and must be obeyed Correct answer.

Explanation

Blue circular signs are mandatory signs: they tell you what you must do, such as passing on a particular side, turning in a given direction or keeping to a minimum speed. Prohibitions, by contrast, are shown on circles with a red border.

Question 6Traffic signs, signals and road markings

A circular sign with a red border and a red diagonal stroke across a black symbol means:

  1. The activity shown is recommended
  2. The activity shown is prohibited Correct answer.
  3. The sign applies only at night
  4. A warning of a hazard ahead

Explanation

Red-ringed circular signs with a diagonal stroke are prohibition signs, and the symbol inside shows what is forbidden. Hazard warnings use triangular signs with a red border, so the shape alone tells you which kind of message you are reading.

Question 7Traffic signs, signals and road markings

Broken white lines between two lanes in the same direction mean that:

  1. No vehicle may cross them at any time
  2. You may change lanes if it is safe Correct answer.
  3. They mark the edge of the carriageway
  4. They separate opposing traffic streams

Explanation

Broken (dashed) white lines show that lane changing is permitted when it is safe and after you have signalled. A continuous line is the marking that forbids crossing.

Question 8Traffic signs, signals and road markings

Broad white stripes painted across the road at a junction indicate:

  1. A place where overtaking is permitted
  2. A zone where you must sound your horn
  3. A parking bay for delivery vehicles
  4. A pedestrian crossing Correct answer.

Explanation

Zebra-type stripes mark a pedestrian crossing, where people on foot have priority over vehicles. Approach at a speed that lets you stop and give way to anyone already on the crossing or about to step onto it.

Question 9Traffic signs, signals and road markings

A police officer is directing traffic at an intersection while the signals show green. Whose instruction must you follow?

  1. The road markings painted at the junction
  2. Whichever allows you to move first
  3. The police officer's signals Correct answer.
  4. The green traffic light

Explanation

Directions given by a police officer on duty override traffic lights, signs and road markings. Follow the officer's hand and arm signals even when they conflict with the signal heads.

Question 10Traffic signs, signals and road markings

You are on a two-way road with a double solid yellow line in the centre. What does this mean?

  1. Crossing the line to overtake is prohibited Correct answer.
  2. Overtaking is allowed if the road ahead is clear
  3. It marks a lane reserved for slow vehicles
  4. You may cross it whenever you signal first

Explanation

Double continuous yellow lines separate opposing traffic and may not be crossed for overtaking or U-turns. You may cross only where the line is broken or where a sign or opening specifically permits it.

Question 11Traffic signs, signals and road markings

The light turns amber (yellow) as you approach. What should you do?

  1. Continue at the same speed without looking
  2. Accelerate to clear the junction before red
  3. Stop, unless you are too close to stop safely Correct answer.
  4. Reverse back from the stop line

Explanation

Amber warns that the signal is about to turn red, so you must stop at the line unless you are so close that stopping could itself cause a collision. Speeding up to beat the red is an offence and a common cause of junction crashes.

Question 12Traffic signs, signals and road markings

A red circle containing the number 80 in black is best described as:

  1. The maximum speed limit Correct answer.
  2. An advisory speed for wet weather
  3. The distance to the next town
  4. The minimum speed for the road

Explanation

Numbers inside a red ring set the maximum legal speed in kilometres per hour for that stretch of road. A minimum speed is shown on a blue circle, and the end of a limit is marked by the same sign crossed by a diagonal bar.

Question 13Traffic signs, signals and road markings

A red circle containing a white horizontal bar means:

  1. One-way traffic ahead
  2. Stop and wait for a green light
  3. No entry for vehicles Correct answer.
  4. Road closed to pedestrians only

Explanation

The white bar on a red disc is the no-entry sign: vehicles must not pass, usually because the road is one-way towards you. The direction in which traffic is allowed to flow is shown separately by a one-way sign with an arrow.

Question 14Traffic signs, signals and road markings

A blue circular sign showing three arrows chasing each other in a circle tells you that:

  1. The road ends ahead
  2. You must travel around a roundabout Correct answer.
  3. A compulsory U-turn is required
  4. Traffic circulates in both directions

Explanation

Blue circular signs give mandatory instructions, and this one directs traffic to circulate around a roundabout. Enter only when it is safe, giving way to vehicles already circulating.

Question 15Traffic signs, signals and road markings

Warning signs that alert drivers to a hazard ahead are normally:

  1. Yellow rectangles with black text
  2. Triangles with a red border and white centre Correct answer.
  3. Red octagons with white text
  4. Blue circles with white symbols

Explanation

Triangular signs with a red border warn of hazards such as bends, junctions, pedestrian crossings or slippery surfaces. Prohibitions are circular with a red ring, and mandatory instructions are blue circles.

Question 16Traffic signs, signals and road markings

A green light shows together with a green arrow pointing right. What does this allow?

  1. Turning in the direction of the arrow only Correct answer.
  2. Any movement, as the light is green
  3. A U-turn anywhere in the junction
  4. Proceeding straight only

Explanation

A green arrow authorises movement only in the direction it points, normally from the lane designated for that movement. Other movements must wait for their own green signal or arrow.

Question 17Traffic signs, signals and road markings

A blue disc with a red border, a red diagonal and a white letter P means:

  1. Parking is free for one hour
  2. Parking is not permitted Correct answer.
  3. A public car park entrance
  4. Parking only for disabled drivers

Explanation

The red ring and diagonal signal a prohibition, and the letter P identifies the activity, so the sign forbids parking along that stretch. Where a red cross replaces the single diagonal, stopping is forbidden as well as parking.

Question 18Traffic signs, signals and road markings

A blue circle containing a white number, such as 60, indicates:

  1. The maximum speed on this road
  2. The minimum speed you must maintain Correct answer.
  3. The number of the route ahead
  4. The distance to a service station

Explanation

A number on a blue circular sign sets a minimum speed that vehicles are expected to keep up with where conditions allow. Maximum limits, by contrast, appear inside a red ring on a white background.

Question 19Traffic signs, signals and road markings

A red circle containing two car symbols, the left one red and the right one black, means:

  1. Two-way traffic ahead
  2. A car park is on the right
  3. Cars may use the left lane only
  4. Overtaking is prohibited Correct answer.

Explanation

This prohibition sign forbids overtaking, usually because visibility or the road layout makes it dangerous. The ban continues until an end-of-prohibition sign or a marking that permits overtaking appears.

Question 20Traffic signs, signals and road markings

At a railway level crossing, a red light flashes and a bell rings. What must you do?

  1. Cross quickly if the barrier is still up
  2. Drive around the barrier if it is down
  3. Stop and wait until the signals stop Correct answer.
  4. Stop only if a train is visible

Explanation

Flashing red lights and bells mean a train is approaching, so you must stop short of the crossing and wait until the lights and bells stop. Never go around a lowered barrier, even if no train can be seen.

Question 21Traffic signs, signals and road markings

You have a green light but the exit from the intersection is blocked by queued traffic. What is the correct action?

  1. Enter and stop in the middle of the junction
  2. Wait behind the stop line until the exit clears Correct answer.
  3. Drive onto the pavement to pass the queue
  4. Enter slowly and sound your horn

Explanation

A green light allows you to proceed only if you can clear the intersection; entering when the far side is blocked leaves you stranded across the junction. Wait behind the line until there is room on the other side.

Question 22Traffic signs, signals and road markings

Two junctions look similar, but one has a STOP sign and the other a give-way triangle. Which statement is correct?

  1. Neither requires a stop if the road is empty
  2. Only the STOP sign requires a full stop every time Correct answer.
  3. Only the give-way sign requires a full stop
  4. Both require a complete stop at all times

Explanation

A STOP sign obliges you to bring the vehicle to a complete halt at the line on every occasion before entering the road. At a give-way sign you must yield, but you need stop only when traffic or pedestrians make it necessary.

Question 23Traffic signs, signals and road markings

A continuous white line separates your lane from the lane on your right. What does it mean?

  1. You may cross it to overtake a slow vehicle
  2. It marks the edge of the carriageway only
  3. You must not cross it to change lanes Correct answer.
  4. It separates traffic moving in opposite directions

Explanation

Continuous white lines divide lanes carrying traffic in the same direction and must not be crossed, so you wait for the line to become broken before changing lanes. Yellow lines, not white ones, are used to separate opposing flows.

Question 24Traffic signs, signals and road markings

You meet an area of white diagonal stripes (hatching) bounded by a continuous white line. How should you treat it?

  1. Keep off it and stay in your lane Correct answer.
  2. Drive over it whenever it is empty
  3. Use it as a lane when traffic is heavy
  4. Park on it while loading goods

Explanation

Hatched areas bounded by a continuous line are closed to traffic; they separate opposing streams or protect vehicles waiting to turn. You may enter them only in an emergency or when directed to do so by a police officer.

Question 25Traffic signs, signals and road markings

You arrive at a signalised intersection where the lights are completely dark because of a power failure. What should you do?

  1. Proceed with caution and give way Correct answer.
  2. Treat the junction as if you have priority
  3. Drive through at normal speed without looking
  4. Wait at the stop line until power returns

Explanation

A dark signal is treated as an uncontrolled intersection: slow down, be ready to stop and give way to traffic already in the junction or approaching with priority. The absence of a light does not give anyone an automatic right of way.

Question 26Traffic signs, signals and road markings

What shape is a STOP sign?

  1. Triangular
  2. Octagonal Correct answer.
  3. Rectangular
  4. Circular

Explanation

The eight-sided shape belongs only to STOP signs, so the sign can be recognised even when dirt, distance or poor light hides the word. No other sign uses an octagon, which is why drivers can react to the shape alone.

Question 27Traffic signs, signals and road markings

A downward-pointing triangle with a red border means:

  1. You must give way Correct answer.
  2. No entry
  3. Road narrows ahead
  4. You must stop

Explanation

The inverted triangle is the give-way sign: you must let traffic on the road you are joining pass before you enter it. A complete stop is only needed when traffic or visibility makes it necessary.

Question 28Traffic signs, signals and road markings

A circular sign with a blue background and a white symbol tells you:

  1. A hazard ahead
  2. Something you must do Correct answer.
  3. Something you must not do
  4. A place of interest

Explanation

Blue circles carry mandatory instructions, meaning an action you are required to take, such as following a direction or keeping to a minimum speed. The colour and shape together separate an order from a warning or a prohibition.

Question 29Traffic signs, signals and road markings

A blue rectangular sign with a white letter P means:

  1. Parking is permitted Correct answer.
  2. No stopping at any time
  3. A pedestrian zone begins
  4. Parking is prohibited

Explanation

The white P on a blue rectangle marks a place where you may park, often with a plate showing any time limit or charge. The same letter inside a red circle with a diagonal would give the opposite instruction.

Question 30Traffic signs, signals and road markings

A white arrow painted in your lane points straight ahead. What does it mean?

  1. You must turn right
  2. You may turn left
  3. You must go straight ahead Correct answer.
  4. The lane ends ahead

Explanation

Arrows painted in a lane are compulsory: they show the only movement permitted from that lane. If you need a different direction you must move to the correct lane before the junction.

Question 31Traffic signs, signals and road markings

Red and amber lights showing together mean:

  1. Get ready but do not go yet Correct answer.
  2. Stop at once and wait
  3. You may go if the way is clear
  4. The signals have failed

Explanation

Red and amber together are a warning that green is about to appear. You should prepare to move but must stay stopped until the green light shows.

Question 32Traffic signs, signals and road markings

A red traffic light means you must stop:

  1. Only if traffic is coming
  2. Anywhere in the junction
  3. Only if a pedestrian is waiting
  4. At the stop line Correct answer.

Explanation

A red light requires a complete stop at the stop line, or before the crossing if no line is painted. Stopping past the line can block pedestrians or traffic crossing on their own green.

Question 33Traffic signs, signals and road markings

A flashing amber light at a junction means:

  1. Stop and wait for green
  2. Ignore the signals entirely
  3. Speed up to clear the junction
  4. Proceed if clear Correct answer.

Explanation

A flashing amber light shows that the signals are not controlling priority, so you proceed only when it is safe and give way as required. It is not the same as a steady amber, which warns that red is about to follow.

Question 34Traffic signs, signals and road markings

Yellow zigzag lines along the kerb outside a school mean:

  1. You may stop to set down children
  2. Deliveries may stop briefly
  3. Do not park or wait there Correct answer.
  4. Parking is free after school hours

Explanation

The zigzag marks the approach to a school crossing, where a stopped vehicle would hide children from other drivers. The area must be kept completely clear, including at times when children are not present.

Question 35Traffic signs, signals and road markings

You want to turn right at a junction marked with a yellow box, but your exit is blocked. What should you do?

  1. Wait outside until the exit clears Correct answer.
  2. Enter the box and wait
  3. Enter only if you can stop inside it
  4. Sound the horn and edge forward

Explanation

A yellow box may only be entered when your exit is clear, so that you never come to rest inside it. Waiting behind the box keeps the junction free for cross traffic when the lights change.

Question 36Traffic signs, signals and road markings

A double broken white line across your lane at a junction means:

  1. Give way to traffic on that road Correct answer.
  2. The lane ahead is closed
  3. You have priority over joining traffic
  4. Stop before crossing the line

Explanation

The double broken line is the give-way line, matched to the give-way sign or triangle. You must yield to traffic already on the road you are entering, stopping only if that traffic requires it.

Question 37Traffic signs, signals and road markings

Black and white chevron signs placed around the outside of a bend indicate:

  1. The end of a dual carriageway
  2. A parking area
  3. A sharp change of direction Correct answer.
  4. A pedestrian crossing ahead

Explanation

Chevron boards trace the outside of a bend so drivers can judge its direction and severity, particularly in darkness or bad weather. They reinforce the warning sign placed before the curve.

Question 38Traffic signs, signals and road markings

A red X displayed above a lane on an overhead gantry means:

  1. The lane will open shortly
  2. The lane is for buses only
  3. Reduce speed in that lane
  4. Lane closed to traffic Correct answer.

Explanation

The red X closes the lane, usually because of an incident, roadworks or a maintenance vehicle ahead. You must move to a lane showing a green light or a white arrow before you reach the gantry.

Question 39Traffic signs, signals and road markings

A green arrow pointing left shows while the main light is red. What does this allow?

  1. Turning left only after the main light turns green
  2. Going straight on
  3. Turning left if the way is clear Correct answer.
  4. Any movement through the junction

Explanation

The green arrow gives a protected movement in the arrow direction while conflicting traffic is held at red. You may make that turn at once, provided the way ahead is clear.

Question 40Traffic signs, signals and road markings

A large green rectangular sign on a highway gives:

  1. Temporary roadworks warnings
  2. Prohibitions for certain vehicles
  3. Directions to places ahead Correct answer.
  4. Speed limits in force

Explanation

Green rectangular signs are direction signs, showing destinations, route numbers and distances. Orders such as limits and prohibitions are given on circular signs.

Question 41Traffic signs, signals and road markings

Temporary signs with a yellow background are used to:

  1. Indicate a hospital
  2. Warn of roadworks Correct answer.
  3. Mark a school zone
  4. Show permanent speed limits

Explanation

A yellow background marks a temporary sign, typically at roadworks or for a short-term hazard. It takes priority over the permanent signs until the works are removed.

Question 42Traffic signs, signals and road markings

At a pedestrian crossing the signal shows a flashing green figure. What should you do?

  1. Wait for the next phase
  2. Cross at a leisurely pace
  3. Finish crossing promptly Correct answer.
  4. Turn back to the pavement

Explanation

A flashing green figure means the pedestrian phase is ending and traffic will soon be released. If you have already started, complete the crossing without delay; do not begin a new crossing.

Question 43Traffic signs, signals and road markings

A blue rectangular sign with a large white arrow pointing straight up means:

  1. No entry ahead
  2. Turn right ahead
  3. Two-way traffic ahead
  4. The road is one-way Correct answer.

Explanation

A single large upward arrow on a blue rectangle marks a one-way street, in which all traffic travels in the direction shown. Entering against the arrow is a serious offence.

Question 44Traffic signs, signals and road markings

A blue rectangular sign showing a white letter H indicates:

  1. A hotel
  2. A helipad
  3. A highway entrance
  4. A hospital Correct answer.

Explanation

The white H on blue marks a hospital, warning drivers that ambulances may join the road at short notice. Noise should be kept down and horn use avoided in the area.

Question 45Traffic signs, signals and road markings

A circular sign with a red border showing a pedestrian symbol on a white background means:

  1. Pedestrian crossing ahead
  2. No pedestrians Correct answer.
  3. Pedestrians only
  4. Pedestrians must use the underpass

Explanation

A pedestrian symbol inside a red ring is a prohibition, banning people on foot from that road, as on highways and in tunnels. A blue circle with the same symbol would instead set aside the route for pedestrians.

Question 46Traffic signs, signals and road markings

A green filter arrow goes out while the main green light stays on. What should you do?

  1. Continue as if the arrow were still showing
  2. Stop immediately at the line
  3. Sound your horn and turn
  4. Proceed when that movement is clear Correct answer.

Explanation

The arrow gave your movement protected priority; once it goes out that protection ends, although the main green may still permit the movement. You may proceed only after checking that conflicting traffic and pedestrians have cleared.

Question 47Traffic signs, signals and road markings

Your light turns green, but a vehicle from the previous phase is still clearing the junction ahead. What should you do?

  1. Sound your horn and drive on
  2. Move into the junction and wait beside it
  3. Flash your lights and proceed
  4. Wait until the junction is clear Correct answer.

Explanation

A green light authorises you to go only when the way is actually clear; it does not give a right to push into an occupied junction. Waiting prevents a block that could trap you when your own phase ends.

Question 48Traffic signs, signals and road markings

A triangular warning sign has a rectangular plate beneath it showing '300 m'. What does the plate mean?

  1. The hazard is 300 metres ahead Correct answer.
  2. The roadworks end in 300 metres
  3. The restriction lasts 300 metres
  4. A speed of 30 applies

Explanation

A distance plate under a warning sign tells you how far ahead the hazard begins, so you can adjust speed in good time. It measures distance to the hazard, not the length of a restriction.

Question 49Traffic signs, signals and road markings

An overhead gantry shows a white arrow pointing down over your lane and a red X over the lane to your right. What does this mean?

  1. Both lanes are open to traffic
  2. The right lane is for overtaking only
  3. Left lane open, right lane closed Correct answer.
  4. Your lane is closed, move right

Explanation

A white downward arrow confirms the lane is open, while a red X closes the lane it is displayed over. Stay in a lane showing a white arrow or green light and do not move into the closed lane.

Question 50Traffic signs, signals and road markings

A warning sign shows a car with skid marks and it has started to rain. What should you do?

  1. Stop and switch on hazard lights
  2. Slow down, avoid harsh braking Correct answer.
  3. Keep your speed and brake later
  4. Change lane and accelerate

Explanation

The skid symbol warns of a slippery surface, and rain makes it far more slippery still. Ease off the speed and use gentle braking, acceleration and steering so the tyres keep their grip.
