Question 1Traffic rules, road signs and road markings
You are driving along a road in Singapore that has no speed limit signs. What is the default speed limit that applies?
- 40 km/h
- 50 km/h Correct answer.
- 60 km/h
- 70 km/h
Explanation
Where no speed limit is displayed, the default limit for that class of road applies. For ordinary roads in Singapore this default is 50 km/h, so the limit stays in force even when no sign is visible. Lower posted limits, such as in school zones, override the default.
Question 2Traffic rules, road signs and road markings
Unless a sign shows a lower figure, what is the maximum speed allowed on a Singapore expressway?
- 60 km/h
- 90 km/h Correct answer.
- 110 km/h
- 70 km/h
Explanation
Expressways in Singapore are subject to a maximum limit of 90 km/h unless signs indicate otherwise. Some stretches carry a lower posted limit, which must be obeyed. The limit applies in good conditions; heavy rain or poor visibility requires you to slow well below it.
Question 3Traffic rules, road signs and road markings
You approach a STOP sign at a junction. What must you do?
- Slow down and proceed without stopping if the road looks clear
- Stop only if there is traffic on the main road
- Stop and then reverse to get a better view of the traffic
- Bring the vehicle to a complete stop before the stop line Correct answer.
Explanation
A STOP sign requires a complete halt, not merely a slow-down, at the stop line or before entering the junction. After stopping you must give way to traffic on the road you are joining. Rolling through the sign, even when the road appears empty, is an offence.
Question 4Traffic rules, road signs and road markings
A circular sign with a red background and a single white horizontal bar means:
- No parking
- No entry for vehicular traffic Correct answer.
- Road narrows ahead
- No overtaking
Explanation
The red disc with a white horizontal bar is the international 'No Entry' sign. It marks a road or lane you must not drive into, commonly placed at the exit of a one-way street. Entering against it is a traffic offence and a serious hazard.
Question 5Traffic rules, road signs and road markings
A broken white line separates two traffic lanes. What does it allow?
- Crossing it only to overtake on the left
- Never crossing it under any circumstances
- Crossing it to change lanes when it is safe to do so Correct answer.
- Driving along it to straddle both lanes
Explanation
A broken or dashed line indicates lanes that you may cross, provided you signal and it is safe. You should not straddle the line or weave between lanes. A continuous line, by contrast, must not be crossed.
Question 6Traffic rules, road signs and road markings
You are on a road with two lanes in your direction and the road ahead is clear. Which lane should you use?
- The left lane, unless you are overtaking Correct answer.
- Either lane, changing between them whenever you wish
- The right lane, so that you can see further ahead
- The lane that gives the smoothest ride
Explanation
The rule is to keep to the left lane and use the right lane only when overtaking or preparing to turn right. Sitting in the right lane when the left lane is free obstructs faster traffic. Return to the left once the overtaking manoeuvre is complete.
Question 7Traffic rules, road signs and road markings
An ambulance with its siren and beacon on approaches from behind. What should you do?
- Speed up so it can follow closely behind you
- Hold your speed and lane so it can choose a side to pass
- Move to the left, slow down or stop, and let it pass Correct answer.
- Brake hard and stop in the middle of your lane
Explanation
You must give way to emergency vehicles displaying sirens and beacons. Move aside safely, usually to the left, and slow or stop until it has passed. Do not brake suddenly in the middle of the lane or race ahead of it.
Question 8Traffic rules, road signs and road markings
A solid white line is painted across your lane at a junction. This line is a:
- Stop line Correct answer.
- Box junction boundary
- Give-way line
- Lane divider
Explanation
A single solid white line across the lane marks where vehicles must stop when a stop signal or STOP sign applies. You are required to halt with your vehicle behind it. Stopping beyond it can block pedestrians or encroach on the junction.
Question 9Traffic rules, road signs and road markings
You are passing a school zone sign while children are arriving for school. What speed limit applies?
- 50 km/h
- 30 km/h
- 60 km/h
- 40 km/h Correct answer.
Explanation
School zones in Singapore carry a reduced limit of 40 km/h when children are present. The lower limit is displayed on the school zone sign and applies even if the general road limit is higher. Reduce speed further if children are near or crossing the road.
Question 10Traffic rules, road signs and road markings
Two continuous white lines run along the centre of the road. What do they mean?
- You may cross them to turn into a side road on the right
- You may cross them to overtake if the road ahead is clear
- You must not cross them, including to make a U-turn Correct answer.
- They apply only during peak traffic hours
Explanation
Double continuous white lines prohibit crossing, overtaking and U-turns across them. They are used where visibility or road layout makes such manoeuvres unsafe. The restriction applies at all times, regardless of traffic volume.
Question 11Traffic rules, road signs and road markings
A double yellow line is painted along the edge of the road. What does it mean?
- Parking is prohibited at all times Correct answer.
- Loading and unloading is always permitted there
- Parking is allowed outside office hours
- You may park for up to 15 minutes
Explanation
Double yellow lines along the kerb indicate that parking is prohibited at all times, day or night. They are drawn where parked vehicles would obstruct traffic or sight lines. Loading or waiting there is not a permitted substitute for parking.
Question 12Traffic rules, road signs and road markings
You arrive at a Give Way line at a junction. What does the line require of you?
- Complete a full stop and wait for a green light
- Slow down and give way to traffic on the road you are joining Correct answer.
- Sound your horn before moving out
- Move out first if you are turning left
Explanation
A Give Way line requires you to yield to traffic already on the major road before entering it. Unlike a STOP sign, it does not always require a complete halt, but you must be able to stop if necessary. Enter only when there is a safe gap.
Question 13Traffic rules, road signs and road markings
The traffic light turns amber as you approach a junction. What should you do?
- Accelerate to clear the junction before the red light appears
- Continue at the same speed in every situation
- Stop immediately at whatever point you have reached
- Stop before the line unless you are so close that stopping would be unsafe Correct answer.
Explanation
Amber warns that the light is about to turn red, so you should stop if you can do so safely. If you are already too close to stop without braking sharply, continue through and clear the junction. Accelerating to beat the red light risks a collision.
Question 14Traffic rules, road signs and road markings
The traffic lights at a junction are flashing amber. What does this mean?
- Proceed with caution and give way to other road users Correct answer.
- Only vehicles turning left may proceed
- Stop completely and wait for a green light
- The junction is closed and no vehicle may enter
Explanation
A flashing amber signal means the lights are not controlling priority, so you must proceed carefully and yield to other traffic and pedestrians. Treat the junction as an uncontrolled one. Do not assume you have the right of way.
Question 15Traffic rules, road signs and road markings
As you enter a roundabout, you must give way to:
- Vehicles queuing behind you
- Buses and taxis only
- Traffic approaching from the left
- Traffic already in the roundabout coming from your right Correct answer.
Explanation
Vehicles entering a roundabout must yield to traffic already circulating, which approaches from the right. Wait for a safe gap before joining the flow. Once inside, signal clearly before leaving at your exit.
Question 16Traffic rules, road signs and road markings
On an ordinary two-way road, which side should you use to overtake another vehicle?
- Whichever side has the most space
- The right Correct answer.
- The left, if the road there is clear
- Either side, provided you signal
Explanation
Overtaking is done on the right so that you pass on the side other drivers expect. Overtaking on the left is prohibited except in specific situations such as queued traffic moving in lanes. Signal early and make sure the road ahead is clear before pulling out.
Question 17Traffic rules, road signs and road markings
How many demerit points are awarded to a driver who beats a red light?
- 24
- 12 Correct answer.
- 8
- 6
Explanation
Beating a red light carries 12 demerit points, one of the highest penalties for a common traffic offence. Points accumulate and can lead to suspension. The offence also applies where a red light controls a filter lane.
Question 18Traffic rules, road signs and road markings
A blue circular sign with a red border and a red cross across it means:
- No entry
- No U-turn
- No parking
- No stopping Correct answer.
Explanation
The blue disc with a red border and a red diagonal cross means no stopping at any time, which is stricter than a no-parking sign. You may not wait, set down or pick up passengers there. A single diagonal line instead of a cross indicates no parking.
Question 19Traffic rules, road signs and road markings
At what times must a vehicle's headlights be switched on?
- Between 6pm and 6am
- Between 7.30pm and 7.30am
- Between 7pm and 7am Correct answer.
- Between 8pm and 8am
Explanation
Vehicle lights must be used from 7pm to 7am. They must also be switched on at any time when visibility is poor, such as during heavy rain or haze. Driving without lights when required is an offence and makes your vehicle hard to see.
Question 20Traffic rules, road signs and road markings
You drive a taxi on a road that has bus stops and marked taxi stands. Where may you stop to pick up or set down passengers?
- On the road within the bus stop markings
- Anywhere along the road if your hazard lights are on
- At a bus stop when no bus is in sight
- Within a marked taxi stand Correct answer.
Explanation
Taxis may pick up and set down passengers only within a marked taxi stand, or where stopping is otherwise lawful. Bus stops and their approach markings are reserved for buses. Hazard lights do not make an illegal stop lawful.
Question 21Traffic rules, road signs and road markings
A normal bus lane is in operation. May a taxi be driven in that lane?
- No, bus lanes are reserved strictly for buses
- Only when carrying more than two passengers
- Only when no bus is visible in the lane
- Yes, taxis are permitted to use bus lanes during operating hours Correct answer.
Explanation
Taxis are among the vehicle types allowed to use bus lanes during their operating hours. The lane is intended to keep public passenger transport moving during peak periods. Other vehicles must stay out of it while it is in operation.
Question 22Traffic rules, road signs and road markings
A vehicle ahead of you has stopped at a pedestrian crossing and you intend to carry straight on. What should you do?
- Move into the opposite lane to pass it
- Sound your horn and continue past
- Slow down and be ready to stop, without overtaking the stopped vehicle Correct answer.
- Overtake it quickly while the crossing looks clear
Explanation
You must not overtake a vehicle that has stopped at a pedestrian crossing, because a pedestrian may be hidden in front of it. Approach slowly and be prepared to stop. Only continue once you can see that the crossing is clear.
Question 23Traffic rules, road signs and road markings
Under what circumstances may you make a U-turn in Singapore?
- Only where a U-turn sign or road marking permits it Correct answer.
- Anywhere the road is wide enough, provided you signal
- At any junction where the light is green
- Across a double white line when no traffic is coming
Explanation
U-turns are permitted only where a sign or road marking expressly allows them. A green light alone does not authorise a U-turn at a junction. Signalling does not make a prohibited U-turn lawful.
Question 24Traffic rules, road signs and road markings
A driver accumulates 24 demerit points within 24 months. What is the result?
- Being required to retake the theory test
- A fine with no effect on the licence
- A written warning with no further action
- The driving licence is suspended Correct answer.
Explanation
Reaching 24 demerit points within 24 months results in suspension of the driving licence. New drivers on probation face suspension at a lower threshold. Demerit points remain on record and are counted over the 24-month period.
Question 25Traffic rules, road signs and road markings
You are turning right at a junction and the exit on the far side is partly blocked by oncoming traffic. When may you wait inside the yellow box marking?
- When more than half of your vehicle is already inside the box
- When the only reason you cannot clear it is oncoming traffic Correct answer.
- When you have sounded your horn to warn other drivers
- When the light has already turned amber
Explanation
The general rule is not to enter a yellow box unless your exit is clear. A right-turning vehicle may wait in the box only where oncoming traffic is the sole reason it cannot complete the turn. The box must be cleared as soon as the way ahead is clear.
Question 26Traffic rules, road signs and road markings
You are driving on a Singapore road where no speed limit sign is displayed. What is the general speed limit that applies?
- 70 km/h
- 60 km/h
- 50 km/h Correct answer.
- 40 km/h
Explanation
Where no speed limit sign is displayed, the general limit on Singapore roads is 50 km/h. Higher limits apply only where a sign shows them, and expressways are signed separately.
Question 27Traffic rules, road signs and road markings
You are approaching an octagonal red sign with the word STOP on it at a junction. What must you do?
- Slow down and continue if the road appears clear.
- Sound your horn before moving off.
- Stop only if other traffic is approaching.
- Bring the vehicle to a complete stop at the stop line and give way. Correct answer.
Explanation
A STOP sign requires a complete stop at the stop line every time, even if the road looks clear. You then give way to traffic before moving off.
Question 28Traffic rules, road signs and road markings
Warning signs that alert you to hazards such as a bend or a road hump are normally displayed in which form?
- A blue circle with a white symbol
- A red triangle with a white centre Correct answer.
- A green square with white lettering
- A yellow diamond with black edges
Explanation
Warning signs are triangles with a red border and a white background carrying a black symbol. The triangular shape sets them apart from prohibitory signs, which are circular.
Question 29Traffic rules, road signs and road markings
The line separating your lane from the lane beside you is a broken white line. What does it mean?
- You must not cross it at any time.
- You may cross it when it is safe to do so. Correct answer.
- You may cross it only when a police officer directs you.
- You may cross it only to overtake a slow vehicle.
Explanation
A broken (dashed) white line separates lanes and may be crossed to change lanes when it is safe. It is the continuous white line that must not be crossed.
Question 30Traffic rules, road signs and road markings
You are approaching a junction marked with a yellow box on the road. When may you enter the box?
- Only when your exit from the box is clear. Correct answer.
- Whenever the traffic light is green in your favour.
- Only when you intend to turn left.
- Whenever no other vehicle is inside the box.
Explanation
A yellow box junction must be kept clear at all times. You should only enter it when you can drive right through and out the other side without stopping.
Question 31Traffic rules, road signs and road markings
You see a red circle containing a horizontal white bar on a sign at the entrance to a road. What does it mean?
- No entry from this direction. Correct answer.
- Road closed to heavy vehicles only.
- No overtaking allowed.
- No parking at any time.
Explanation
A red circle with a horizontal white bar is the No Entry sign. It means no vehicle may proceed past it from that direction.
Question 32Traffic rules, road signs and road markings
You come across an area of the road painted with diagonal stripes inside a bordered outline. What do these markings mean?
- You must not drive over them. Correct answer.
- They mark a lane reserved for buses.
- You may drive over them if no other vehicle is nearby.
- They show where you may park during off-peak hours.
Explanation
Hatched areas marked with diagonal stripes separate traffic streams or protect turning areas and must not be driven on. Only in an emergency should a vehicle enter them.
Question 33Traffic rules, road signs and road markings
You are driving on an expressway. When may you use the road shoulder?
- In an emergency or when your vehicle breaks down. Correct answer.
- When you need to answer a telephone call.
- Whenever traffic in the left lane is moving slowly.
- When you want to overtake a long queue of vehicles.
Explanation
The road shoulder on an expressway is reserved for emergencies such as a breakdown. It is not a driving or overtaking lane, and using it for other purposes is an offence.
Question 34Traffic rules, road signs and road markings
In good, dry conditions, what minimum gap should you keep behind the vehicle in front?
- At least two seconds Correct answer.
- One car length for every 10 km/h of speed
- At least five seconds
- About half a second
Explanation
In good conditions you should keep at least a two-second gap so that you have time to react if the vehicle ahead brakes suddenly. The gap should be increased in rain or at night.
Question 35Traffic rules, road signs and road markings
At a junction, a police officer is directing traffic by hand signals while the traffic lights are still working. Whose signals must you obey?
- Whichever of them gives you the right of way.
- The traffic lights, because they operate automatically.
- The police officer's signals. Correct answer.
- The vehicle in front of you.
Explanation
You must obey a police officer directing traffic even when the lights are working, because the officer may be overriding the signals to deal with an incident or congestion.
Question 36Traffic rules, road signs and road markings
You are driving along a slip road to join an expressway. What should you do?
- Give way to traffic already on the expressway. Correct answer.
- Sound your horn to warn traffic on the expressway.
- Stop at the end of the slip road and wait for a gap.
- Expect expressway traffic to give way to you.
Explanation
Traffic already on the expressway has the right of way. Use the slip road to build up speed and merge smoothly into a safe gap rather than stopping at the end.
Question 37Traffic rules, road signs and road markings
You are turning right at a junction on a two-way road and oncoming traffic is approaching. Where should you wait?
- In the left-hand lane, with your right signal on.
- Across the centre line, with your wheels turned right.
- Just left of the centre line, with your wheels straight. Correct answer.
- Behind the stop line until the road is completely empty.
Explanation
Wait to the right of your lane but just left of the centre line, keeping your wheels straight so that a hit from behind will not push you into oncoming traffic. Turn the wheels only as you begin the turn.
Question 38Traffic rules, road signs and road markings
You are driving at night on an unlit road and a vehicle approaches from the opposite direction. What should you do with your headlights?
- Leave them on high beam so you can see the road ahead.
- Flash them to show the other driver that you are there.
- Dip them so you do not dazzle the other driver. Correct answer.
- Switch them off until the vehicle has passed.
Explanation
Dipping your headlights prevents dazzle for the oncoming driver while still letting you see the road. Return to high beam once the vehicle has passed and the road ahead is clear.
Question 39Traffic rules, road signs and road markings
At a junction the light shows a red circle together with a green arrow pointing right. You want to go straight ahead. What should you do?
- Proceed straight ahead only after the vehicles on your right have moved off.
- Sound your horn and wait for a green circle.
- Wait behind the stop line until a green circle shows. Correct answer.
- Proceed straight ahead carefully.
Explanation
A green arrow permits movement only in the direction it points. Because a red circle is also showing, traffic going straight ahead must stay behind the stop line until the light turns green.
Question 40Traffic rules, road signs and road markings
The light turns green for you at a junction, but the traffic ahead is queued across the junction so there is no room on the far side. What should you do?
- Follow the vehicle in front closely so you are not left behind.
- Sound your horn to get the queue moving.
- Move forward and stop in the middle of the junction.
- Wait behind the stop line until there is room on the far side. Correct answer.
Explanation
Even on a green light you must not enter a junction if you would have to stop and block it. Wait behind the stop line until there is space to clear the junction completely.
Question 41Road safety and safe driving behaviour
In good, dry conditions, what is the minimum safe gap you should keep behind the vehicle in front?
- One car length at any speed
- About ten metres at all speeds
- Half a second in slow traffic
- At least two seconds Correct answer.
Explanation
The two-second rule gives you enough time to react and stop if the vehicle ahead brakes suddenly. The gap is measured in time, not distance, so it automatically grows as your speed increases. In rain, poor light or heavy traffic the gap should be widened further.
Question 42Road safety and safe driving behaviour
Which of the following may you do while driving on a public road?
- Type a short reply to a text at a junction
- Hold the phone to your ear in slow-moving traffic
- Speak on a phone through a hands-free kit Correct answer.
- Read a message on your phone while stopped at a red light
Explanation
A driver must not hold or use a mobile phone while driving; a hands-free kit that needs no handling of the device is permitted. The ban applies even when the car is stopped at a red light or in a traffic queue. Handling a phone divides attention and is a serious road safety offence.
Question 43Road safety and safe driving behaviour
You must switch on your vehicle's headlights
- at night and when visibility is seriously reduced Correct answer.
- only when there are other vehicles nearby
- only on the expressway after dark
- only on roads where there are no street lamps at all
Explanation
Headlights must be lit during the hours of darkness and whenever visibility is seriously reduced, for example in heavy rain or haze. Seeing the road is only part of the purpose; headlights also make your vehicle visible to others. Street lighting or the type of road does not remove the requirement.
Question 44Road safety and safe driving behaviour
Before changing lanes on an expressway, you should
- sound your horn to warn other traffic
- depend on your wing mirrors only
- glance over your shoulder to check the blind spot Correct answer.
- switch on your hazard lights briefly
Explanation
Mirrors leave an area alongside and slightly behind the car that cannot be seen from the driving seat. A quick shoulder check confirms that no vehicle is hidden there before you commit to the lane change. Signal early as well so that other drivers know your intention.
Question 45Road safety and safe driving behaviour
A pedestrian is waiting at a zebra crossing as you approach. You should
- slow down and prepare to stop for the pedestrian Correct answer.
- flash your headlights and drive on
- continue because the crossing is not on your side
- sound your horn so that the pedestrian waits for you
Explanation
Drivers must give way to pedestrians at a zebra crossing, so you approach at a speed that lets you stop. The pedestrian has priority once they are at or on the crossing. Sounding the horn or flashing headlights does not give you the right to proceed.
Question 46Road safety and safe driving behaviour
The speed limit in a school zone while children are present is
- 50 km/h
- 30 km/h
- 60 km/h
- 40 km/h Correct answer.
Explanation
School zones in Singapore are signed with a lower limit of 40 km/h when children are present. Children can step into the road without warning, and the reduced limit shortens your stopping distance. The normal road limit resumes outside the zone.
Question 47Road safety and safe driving behaviour
It is raining heavily and the road surface is wet. How should you adjust your driving?
- Keep the same gap and switch on your hazard lights
- Close up so that other drivers cannot cut in
- Drive at the speed limit because it is still legal
- Reduce your speed and increase your following distance Correct answer.
Explanation
Wet roads reduce tyre grip, so braking takes longer and the safe gap must be bigger than two seconds. Lower speed also reduces the chance of aquaplaning and gives you more time to react. Hazard lights must not be used simply because it is raining.
Question 48Road safety and safe driving behaviour
Traffic ahead is queuing and the road beyond a yellow box junction is blocked. You should
- enter the box and wait for the queue to move
- enter the box only if the lights are green
- wait behind the box until there is room beyond it Correct answer.
- use the next lane to drive around the box
Explanation
A yellow box must not be entered unless your exit is clear, so you wait before it rather than stopping on top of it. Blocking the box traps cross traffic and can gridlock the junction. A green light alone does not give you the right to enter if the far side is full.
Question 49Road safety and safe driving behaviour
The light turns amber as you approach a junction and you are close enough to stop safely. What should you do?
- Stop before the stop line Correct answer.
- Sound your horn and continue through
- Accelerate to clear the junction before the red
- Continue only if a pedestrian is waiting
Explanation
Amber means stop unless you are so close that stopping would be unsafe. Since you can stop safely here, you must stop before the stop line. Accelerating to beat the red is a common cause of junction collisions.
Question 50Road safety and safe driving behaviour
The legal limit for alcohol in a driver's breath in Singapore is
- 50 microgrammes per 100 millilitres of breath
- 35 microgrammes per 100 millilitres of breath Correct answer.
- 20 microgrammes per 100 millilitres of breath
- 80 microgrammes per 100 millilitres of breath
Explanation
The prescribed limit is 35 microgrammes of alcohol per 100 millilitres of breath, which corresponds to 80 milligrammes per 100 millilitres of blood. Driving at or above the limit is an offence regardless of whether you feel affected. If you have been drinking, the safe choice is not to drive at all.
