  2. 40 km/h
  3. 60 km/h
  4. 50 km/h Correct answer.

  1. 100 km/h
  2. 90 km/h Correct answer.
  3. 70 km/h
  4. 80 km/h

Explanation

The general speed limit on expressways is 90 km/h unless a lower limit is posted. Some stretches have lower limits because of sharp bends, road works or heavy traffic.

Question 4Traffic rules and regulations

On which side of the road must you drive in Singapore?

  1. On the right
  2. On either side
  3. On the left Correct answer.
  4. Near the centre line

Explanation

Singapore uses left-hand traffic, so vehicles keep to the left side of the road. On multi-lane roads the rightmost lanes are used for overtaking or faster-moving traffic.

Question 5Traffic rules and regulations

You are approaching a zebra crossing and a pedestrian is waiting to cross. What should you do?

  1. Keep your speed because vehicles have priority
  2. Flash your headlights and continue driving
  3. Sound your horn so the pedestrian waits
  4. Slow down and prepare to stop Correct answer.

Explanation

Drivers must give way to pedestrians at zebra crossings. Slow down on approach and stop to let the pedestrian cross safely.

Question 6Traffic rules and regulations

A traffic light turns amber as you approach. When may you continue through the junction?

  1. When the junction ahead is empty of traffic
  2. When you want to avoid waiting at the red light
  3. When the vehicle behind is following closely
  4. When stopping could cause a collision Correct answer.

Explanation

An amber light means stop, unless you are so close to the stop line that stopping abruptly would be dangerous. In that case you may proceed through and clear the junction.

Question 7Traffic rules and regulations

What does a continuous double white line along the centre of the road mean?

  1. You may cross it to enter a side road
  2. You may cross it to overtake when the road is clear
  3. You may cross it outside peak hours
  4. You must not cross it at any time Correct answer.

Explanation

A continuous double white line means no crossing at all, whether to overtake, make a U-turn or enter a side road. It is used where visibility or traffic conditions make crossing unsafe.

Question 8Traffic rules and regulations

You may enter a yellow box junction only when...

  1. The traffic light ahead is green
  2. You are following a large vehicle closely
  3. Your exit from the box is clear Correct answer.

Explanation

A yellow box junction must be kept clear. You may enter only if your exit is clear so that you will not have to stop inside the box.

  1. 80 mg per 100 ml of blood Correct answer.
  2. 20 mg per 100 ml of blood
  3. 50 mg per 100 ml of blood
  4. 100 mg per 100 ml of blood

Explanation

The legal limit is 80 mg of alcohol per 100 ml of blood. Even below this limit, a driver can be convicted if unfit to drive.

  1. It is allowed only on expressways
  2. It is allowed when you stop at a red light
  3. It is allowed for calls under one minute
  4. It is prohibited at all times Correct answer.

Explanation

Holding and using a mobile phone while in control of a vehicle is an offence, even when the vehicle is stopped at a red light or in traffic. Drivers who need to make a call should park safely first.

Question 11Traffic rules and regulations

When you are about to enter a roundabout, you must give way to...

  1. Vehicles approaching from your left
  2. Vehicles following close behind you
  3. Pedestrians standing on the pavement
  4. Circulating traffic from your right Correct answer.

Explanation

Traffic already circulating in the roundabout has priority, and because you drive on the left these vehicles approach from your right. Wait for a safe gap before entering.

Question 12Traffic rules and regulations

On a two-way road, you should normally overtake other vehicles...

  1. On the left
  2. On the right Correct answer.
  3. Only where the speed limit is above 60 km/h
  4. On either side

Explanation

Overtaking is normally done on the right, moving into the opposing lane only when it is safe and legal. Overtaking on the left is permitted only in limited situations, such as when the vehicle ahead is turning right.

Question 13Traffic rules and regulations

Who is required to wear a seatbelt in a car?

  1. All occupants of the car Correct answer.
  2. Only the driver and front passenger
  3. Only passengers aged 18 and above

Seatbelts must be worn by the driver and all passengers, including those in the rear seats. The driver is responsible for ensuring passengers are properly belted.

Question 14Traffic rules and regulations

A child who is below 1.35 metres in height must...

  1. Sit in the front seat with an adult seatbelt
  2. Be held on an adult's lap
  3. Use a suitable child restraint Correct answer.
  4. Stand between the front seats

Explanation

Children below 1.35 m must be secured in a suitable child restraint or booster seat that matches their height and weight. An adult seatbelt alone may not protect them properly.

Question 15Traffic rules and regulations

During bus lane operating hours, a car may use the bus lane...

  1. Only when turning into a side road Correct answer.
  2. To stop briefly and pick up passengers
  3. Whenever the traffic is heavy
  4. To overtake a slow-moving bus

Explanation

Bus lanes are reserved for scheduled buses during operating hours. Other vehicles may enter only briefly when making a permitted turn or entering a property, and must give way to buses.

Question 16Traffic rules and regulations

A driver who accumulates 24 demerit points within 24 months will...

  1. Be required to attend a course only
  2. Pay a fine only
  3. Receive a warning letter
  4. Have their licence suspended Correct answer.

Explanation

Under the demerit points system, reaching 24 points within 24 months results in suspension of the driving licence. The length of suspension depends on the driver's record.

Question 17Traffic rules and regulations

In good, dry weather, what minimum following distance should you keep from the vehicle ahead?

  1. About 2 seconds Correct answer.
  2. About half a second
  3. About 10 seconds
  4. About 1 second

Explanation

The two-second rule gives you time to react and stop if the vehicle ahead brakes suddenly. In rain or poor visibility, increase the gap further.

Question 18Traffic rules and regulations

An ambulance with flashing lights and a siren is approaching from behind. What should you do?

  1. Stop immediately in your lane
  2. Speed up to stay ahead of it
  3. Pull over and let it pass Correct answer.
  4. Sound your horn to warn other traffic

Explanation

Emergency vehicles on call have priority. Move to the side safely, without breaking traffic rules, and let the vehicle pass.

Question 19Traffic rules and regulations

Between 11.30 pm and 7 am, you should not sound your horn in a built-up area except...

  1. To warn of imminent danger Correct answer.
  2. To greet other drivers
  3. When approaching a junction
  4. When overtaking

Explanation

The horn should only be used to warn others of danger. In built-up areas at night, unnecessary horn use is prohibited because it disturbs residents.

Question 20Traffic rules and regulations

What does a double yellow line along the edge of the road mean?

  1. No parking at any time Correct answer.
  2. No parking on weekdays only
  3. Parking is allowed for up to 10 minutes
  4. No parking between 7 am and 7 pm

Explanation

A double yellow line means no parking at any time. A single yellow line restricts parking only during specified hours.

Question 21Traffic rules and regulations

What is the minimum legal tyre tread depth for cars in Singapore?

  1. 3.0 mm
  2. 1.0 mm
  3. 2.5 mm
  4. 1.6 mm Correct answer.

Explanation

Tyres must have at least 1.6 mm of tread across the central three-quarters of the tyre width. Worn tyres reduce grip, especially in wet weather.

Which of these is prohibited on an expressway?

  1. Using the right lane to overtake
  2. Driving at the posted speed limit
  3. Driving with headlights switched on
  4. Reversing on the road Correct answer.

Explanation

Expressways are for continuous forward movement. Reversing, stopping on the shoulder without an emergency, and picking up passengers are prohibited.

Question 23Traffic rules and regulations

You are waiting to turn right at a junction and oncoming vehicles are approaching. You should...

  1. Move out because you reached the junction first
  2. Turn quickly to get through the gap
  3. Give way to oncoming traffic Correct answer.
  4. Expect oncoming vehicles to slow for you

Explanation

Vehicles going straight or turning left from the opposite direction have priority. Wait until the oncoming traffic has passed before completing your right turn.

Question 24Traffic rules and regulations

Why must you not overtake a vehicle that has stopped at a pedestrian crossing?

  1. Overtaking is only allowed on the right
  2. The crossing may be closed to traffic
  3. The stopped vehicle may be broken down
  4. A pedestrian may be hidden from view Correct answer.

Explanation

A vehicle stopped at a pedestrian crossing may be giving way to someone you cannot see. Overtaking in this situation could cause you to hit the pedestrian.

Question 25Traffic rules and regulations

A bus is signalling to move out of a bus stop. What should you do?

  1. Slow down and give way to the bus Correct answer.
  2. Sound your horn to warn the bus driver
  3. Accelerate to pass before the bus moves
  4. Overtake the bus on the left

Explanation

Drivers should give way to buses signalling to leave a bus stop. Slow down and allow the bus to rejoin the traffic stream safely.

Question 26Traffic rules and regulations

Unless signs show a lower limit, what is the maximum speed allowed on a Singapore expressway?

  1. 120 km/h
  2. 100 km/h
  3. 70 km/h
  4. 90 km/h Correct answer.

Explanation

The default speed limit on Singapore expressways is 90 km/h. Where a sign shows a lower figure, that lower limit applies and must be obeyed.

Question 27Traffic rules and regulations

Unless signs show otherwise, what is the maximum speed allowed on an ordinary road in Singapore?

  1. 40 km/h
  2. 70 km/h
  3. 30 km/h
  4. 50 km/h Correct answer.

Explanation

The default limit for ordinary roads is 50 km/h unless a sign states another figure. You must still be able to stop within the distance you can see to be clear, even below the limit.

Question 28Traffic rules and regulations

A police officer is directing traffic at a junction where the lights are still working. Whose signal must you follow?

  1. The pedestrian signal
  2. The vehicle immediately in front
  3. The police officer Correct answer.
  4. The traffic light, because it is automatic

Explanation

Signals given by a police officer on duty override traffic lights, road markings and signs. Follow the officer's directions even if the lights show something different.

Question 29Traffic rules and regulations

What is the minimum age at which you may hold a driving licence for a car in Singapore?

  1. 18 years Correct answer.
  2. 21 years
  3. 19 years
  4. 17 years

Explanation

A person must be at least 18 years old to hold a Class 3 or Class 3A car driving licence in Singapore. A learner must also hold a valid provisional licence while learning.

Question 30Traffic rules and regulations

What does a single yellow line along the edge of a road mean?

  1. Stopping is allowed for up to ten minutes
  2. Loading is allowed at night only
  3. Parking is allowed outside office hours
  4. Parking is prohibited at all times Correct answer.

A pedestrian is waiting to cross at a zebra crossing. What must you do?

  1. Stop and let the pedestrian cross Correct answer.
  2. Sound your horn to warn the pedestrian
  3. Flash your headlights and drive on
  4. Keep going if you are within the speed limit

Explanation

Drivers must give way to pedestrians at zebra crossings, including those waiting to cross. Approach at a speed that lets you stop safely, and never wave a pedestrian on in a way that creates danger.

Question 32Traffic rules and regulations

When must you switch on your vehicle's lights?

  1. Only when it is raining heavily
  2. Only when driving on unlit roads at night
  3. In the dark and in poor visibility Correct answer.
  4. Only when driving on the expressway

Explanation

Lights must be used between 7 pm and 7 am and at any other time when visibility is poor, such as in heavy rain. This helps other road users see you as well as helping you see the road.

Question 33Traffic rules and regulations

You reach a junction with a STOP sign and stop line, and the road is clear. What must you do?

  1. Stop only when another vehicle is coming
  2. Slow down and continue
  3. Sound your horn and go
  4. Stop completely before proceeding Correct answer.

Explanation

A STOP sign requires a complete halt at the stop line, even when nothing appears to be coming. You may then move off only when you are sure the way is clear.

Question 34Traffic rules and regulations

You are approaching a junction controlled by a 'Give Way' sign. What does it require of you?

  1. You may enter without slowing if the road is empty
  2. You must stop and wait for a green light
  3. Slow down and give way to the main road traffic Correct answer.
  4. You have right of way over all other traffic

Explanation

A Give Way sign means you must slow down and be ready to stop so that traffic on the road you are joining has priority. Enter only when there is a safe gap.

Question 35Traffic rules and regulations

You are on a slip road joining an expressway. What is the correct approach?

  1. Use the road shoulder until a gap appears
  2. Expect traffic already on the expressway to give way
  3. Stop at the end of the slip road and wait
  4. Match speed and merge into a safe gap Correct answer.

Explanation

Traffic already on the expressway has priority, so use the slip road to build up a similar speed and join smoothly when a gap is available. Never force your way in or drive along the shoulder.

Question 36Traffic rules and regulations

On a road with three lanes running in the same direction, which lane should you normally use?

  1. The right lane, so you can overtake easily
  2. The left lane, unless you are overtaking Correct answer.
  3. The middle lane, to leave the left lane free
  4. Any lane, as long as you keep within the limit

Explanation

You should keep to the left-hand lane unless you are overtaking or your lane is blocked. Staying in the outer lanes without reason holds up faster traffic and increases lane-changing hazards.

Question 37Traffic rules and regulations

An oncoming vehicle's headlights are dazzling you at night. What should you do?

  1. Speed up to pass the vehicle quickly
  2. Flash your high beam to warn the other driver
  3. Slow down and look to the left edge of your lane Correct answer.
  4. Close your eyes briefly until the vehicle passes

Explanation

Slow down and use the left edge of your lane as a guide so you keep your position without staring into the glare. Once the vehicle has passed, allow your eyes to readjust before resuming normal speed.

Question 38Traffic rules and regulations

You are driving in heavy rain. How should you adjust your driving?

  1. Move to the right lane for better visibility
  2. Keep your speed and switch on hazard lights
  3. Follow the tail lights ahead closely
  4. Reduce speed and increase the gap ahead Correct answer.

Explanation

Wet roads reduce grip and lengthen braking distances, so you should slow down and leave a larger gap than in dry weather. Hazard lights should not be used as an excuse to maintain speed in heavy rain.

Question 39Traffic rules and regulations

You are involved in an accident in which someone is injured. What must you do?

  1. Stop, help the injured and report within 24 hours Correct answer.
  2. Drive on and report at a police station within seven days
  3. Move the vehicles away before calling for help
  4. Leave your details with a bystander and go home

Explanation

You must stop, give whatever assistance you reasonably can and report the accident to the police within 24 hours. If anyone is seriously hurt, call for an ambulance as well.

Question 40Traffic rules and regulations

Before a car may be used on a public road, which of these is legally required?

  1. A valid season parking ticket for your area
  2. Comprehensive insurance that also covers your own repairs
  3. Membership of a vehicle recovery service
  4. Third-party insurance for injury or damage to others Correct answer.

Explanation

At minimum, a vehicle must be covered by third-party insurance against injury to others or damage to their property. Driving without valid insurance is an offence.

Question 41Traffic rules and regulations

What does a broken white line in the centre of the road mean?

  1. You must never cross it to overtake
  2. You may cross it to overtake if safe Correct answer.
  3. It marks the edge of a bus lane
  4. It shows where parking is permitted

Explanation

A broken white line separates opposing streams of traffic and may be crossed when overtaking, provided the road ahead is clear and it is safe. A continuous line, by contrast, must not be crossed.

Question 42Traffic rules and regulations

Your car breaks down on an expressway. What should you do first?

  1. Reverse along the shoulder to the nearest exit
  2. Stop where you are and put out a triangle
  3. Walk along the carriageway to find a telephone
  4. Move onto the shoulder and use hazard lights Correct answer.

Explanation

If the car can still be moved, get it as far onto the left shoulder as possible and switch on the hazard lights. Stay well clear of the carriageway and call for assistance.

Question 43Traffic rules and regulations

Which of these statements about a pedestrian crossing is correct?

  1. You may stop on it briefly to set down a passenger
  2. You may wait on it if no pedestrian is crossing
  3. You must not stop or park on the crossing Correct answer.
  4. You may park on it outside business hours

Explanation

The area of a pedestrian crossing must be kept clear so pedestrians can cross safely and be seen. Stopping or parking on the crossing is an offence, and parking close to it can also block the view of drivers and pedestrians.

Question 44Traffic rules and regulations

A green arrow pointing left is displayed at a junction. What does it allow you to do?

  1. You must come to a full stop first
  2. You may turn left only when a police officer signals
  3. You must wait for the main light to turn green
  4. You may turn left, but only if it is clear Correct answer.

Explanation

A green arrow means you may proceed in the direction the arrow points without waiting for the main light. You must still check that the way ahead is clear, especially for pedestrians crossing the road you are turning into.

Question 45Traffic rules and regulations

For how long must a new driver display probation (P) plates after passing the driving test?

  1. Two years
  2. One year Correct answer.
  3. Three years
  4. Six months

Explanation

A driver who has just passed the test enters a one-year probation period and must display probation plates on the front and rear of the vehicle. During this period a lower demerit point threshold applies.

Question 46Traffic rules and regulations

Within a 12-month period, how many demerit points will cause a probationary driver's licence to be revoked?

  1. 24 points
  2. 8 points
  3. 18 points
  4. 12 points Correct answer.

Explanation

A probationary driver who accumulates 12 demerit points within 12 months has the licence revoked. The driver must then retake and pass the theory and practical tests before driving again.

Question 47Traffic rules and regulations

A police officer lawfully requires you to provide a breath specimen and you refuse without reasonable excuse. What is the likely consequence?

  1. A small fine collected at the roadside
  2. Nothing, because refusal is not an offence in law
  3. You may be arrested and charged with an offence Correct answer.
  4. A verbal warning recorded on file

Explanation

Failing or refusing to provide a breath specimen when lawfully required is an offence, and the driver may be arrested. The court can impose a fine, disqualification from driving or imprisonment.

Question 48Traffic rules and regulations

A vehicle is following you too closely on a wet road. What is the safest response?

  1. Increase the gap ahead and let the driver pass Correct answer.
  2. Switch on your hazard lights and keep going
  3. Speed up to increase the space behind you
  4. Brake sharply to warn the driver behind

Explanation

A tailgater removes your safety margin, so open up extra space in front of you and, when it is safe, let the vehicle pass. Braking sharply or speeding up increases the risk of a collision on a wet surface.

Question 49Traffic rules and regulations

A police officer asks to see your documents while you are driving. Which must you be able to produce?

  1. Your driving licence only
  2. Nothing, unless you are under arrest
  3. Your driving licence and valid insurance Correct answer.
  4. Your identity card only

Explanation

You must be able to produce your driving licence and evidence that the vehicle is insured when asked by an authorised officer. If you cannot produce them on the spot, you may be required to produce them at a police station later.

Question 50Traffic rules and regulations

On a two-way road you see two continuous (unbroken) white lines running along the centre of the carriageway. What do these lines mean?

  1. You may cross them to overtake a slow-moving vehicle
  2. You must not cross or straddle them Correct answer.
  3. They mark the boundary of a bus lane
  4. You may cross them if the road ahead is clear

Explanation

Double continuous white lines in the centre of a two-way road prohibit crossing or straddling them, so no overtaking, U-turn or parking on them is allowed. The restriction is normally imposed where visibility is poor and the risk of a head-on collision is high. Where overtaking is permitted, the centre line is broken rather than continuous.
