Singapore BTT (Basic Theory Test) — Questions and Answers

Question 1: What is the recommended following distance in wet conditions?

The same two-second rule as dry conditions
At least a four-second gap (Correct answer)
As close as possible to see the road ahead
One car length per 10 km/h

Correct answer: At least a four-second gap

In wet conditions, double the following distance to at least four seconds to account for increased braking distances.

Question 2: What should you be especially cautious about near a bus stop?

Road surface damage
Noise pollution
The bus pulling out
Pedestrians crossing the road from behind the bus where they are hidden from view (Correct answer)

Correct answer: Pedestrians crossing the road from behind the bus where they are hidden from view

Pedestrians may suddenly cross the road after alighting from a bus. They can be hidden by the bus until they step into your lane.

Question 3: The traffic light sequence in Singapore is: Red → Red and Amber → Green → ?

Flashing green
Red
Amber (Correct answer)
Green arrow

Correct answer: Amber

The traffic light sequence is Red → Red and Amber → Green → Amber → Red. After green, a steady amber warns drivers to prepare to stop.

Question 4: What must you do when approaching a zebra crossing where a pedestrian is waiting to cross?

Speed up to pass before they step onto the road
Sound your horn to warn them
Slow down and stop to let the pedestrian cross (Correct answer)
Flash your headlights to signal them to wait

Correct answer: Slow down and stop to let the pedestrian cross

You must slow down and stop for pedestrians at zebra crossings. Pedestrians have right of way at zebra crossings once they step onto or are waiting at the crossing.

Question 5: When driving on a two-lane road, which lane should you normally occupy?

The lane with less traffic
Either lane
The left lane (Correct answer)
The right lane

Correct answer: The left lane

In Singapore, the left lane is the normal driving lane. The right lane should be used primarily for overtaking.

Question 6: What should you do when you see a 'Pedestrians Ahead' warning sign?

Only slow down if you see pedestrians
Honk your horn as a warning
Slow down and be especially alert for pedestrians crossing or near the road (Correct answer)
Maintain speed — pedestrians should watch out for cars

Correct answer: Slow down and be especially alert for pedestrians crossing or near the road

The 'Pedestrians Ahead' sign warns you to slow down and be prepared for pedestrians who may be on or near the road.

Question 7: How far from a traffic light junction should you start looking at the signals?

Within 50 metres
Only when directly at the stop line
Only when the car ahead reacts
As soon as they become visible — to plan your approach (Correct answer)

Correct answer: As soon as they become visible — to plan your approach

Observe traffic signals as soon as they become visible so you can plan your approach, adjust speed, and respond safely.

Question 8: What must you do when you see a steady red traffic light?

Slow down and proceed with caution
Stop behind the stop line and wait (Correct answer)
Stop only if other vehicles are present
Proceed if turning left

Correct answer: Stop behind the stop line and wait

A steady red light means you must stop behind the stop line and wait until the light changes. There is no 'turn on red' rule in Singapore.

Question 9: On a road with four lanes in your direction, which lanes are heavy vehicles typically restricted from using?

No restriction applies
The two left lanes
The right-most lane (Correct answer)
The two centre lanes

Correct answer: The right-most lane

Heavy vehicles are typically restricted from using the right-most (fastest) lane on multi-lane roads in Singapore.

Question 10: At a junction with a dedicated right-turn phase, when should you turn right?

When there is a gap in oncoming traffic
Whenever the main light is green
At any time if the road is clear
Only when the right-turn green arrow is shown (Correct answer)

Correct answer: Only when the right-turn green arrow is shown

When a junction has a dedicated right-turn phase (green arrow), you should only turn right when that specific green arrow is displayed.

Question 11: When two vehicles reach a narrow bridge from opposite ends simultaneously, who should give way?

The vehicle going uphill
The heavier vehicle
The vehicle closest to the bridge
The vehicle going downhill (Correct answer)

Correct answer: The vehicle going downhill

The vehicle going downhill should give way to the vehicle going uphill, as it is harder for the uphill vehicle to stop and restart.

Question 12: At a pedestrian crossing, the green man has just turned to flashing green. What should drivers expect?

Pedestrians will run across quickly
No pedestrians will be on the crossing
Some pedestrians may still be on the crossing and need to finish crossing (Correct answer)
The lights are malfunctioning

Correct answer: Some pedestrians may still be on the crossing and need to finish crossing

During the flashing green man phase, some pedestrians (especially elderly or disabled individuals) may still be finishing their crossing. Drivers must be patient.

Question 13: A green arrow pointing right appears alongside a red light. What can you do?

Turn right only, giving way to pedestrians (Correct answer)
Proceed in any direction
Turn right without giving way to anyone
Stop and wait for a full green light

Correct answer: Turn right only, giving way to pedestrians

A green filter arrow allows you to turn in the arrow's direction only, but you must still give way to pedestrians crossing the road you are entering.

Question 14: When can a vehicle legally cross a double white continuous centre line?

To access a property or side road on the other side (Correct answer)
At any time if safe
Never under any circumstances
To overtake a slow vehicle

Correct answer: To access a property or side road on the other side

You may cross double white continuous lines to access a property or side road, or to pass a stationary obstruction, but never to overtake a moving vehicle.

Question 15: At a four-way stop junction, which vehicle proceeds first if all arrive simultaneously?

The largest vehicle
The vehicle on the far left
The vehicle on the right (Correct answer)
The vehicle going straight

Correct answer: The vehicle on the right

When vehicles arrive at the same time, give way to the vehicle on your right. This applies the standard right-of-way rule.

Question 16: A triangular sign with a red border showing an exclamation mark warns of what?

Road works
School zone
General danger or hazard ahead (Correct answer)

Correct answer: General danger or hazard ahead

A triangular warning sign with an exclamation mark alerts drivers to a general danger or hazard ahead that is not covered by a specific sign.

Question 17: A red circular sign showing '5 tonnes' with a lorry symbol means what?

No vehicles over 5 tonnes (Correct answer)
Speed limit for heavy vehicles
Lorry parking for vehicles up to 5 tonnes
5-tonne vehicles only

Correct answer: No vehicles over 5 tonnes

This prohibitory sign means vehicles exceeding the stated weight (5 tonnes) are not permitted on this road.

Question 18: Your vehicle's speedometer reads 60 km/h. Is your actual speed likely to be exactly 60 km/h?

No — speedometers typically read lower than actual speed
No — speedometers typically read slightly higher than actual speed (Correct answer)
Yes — speedometers are always accurate
Only digital speedometers are accurate

Correct answer: No — speedometers typically read slightly higher than actual speed

Most speedometers are calibrated to read slightly higher than the actual speed. This is a safety margin built in by manufacturers.

Question 19: What is the speed limit for heavy goods vehicles on expressways in Singapore?

60 km/h (Correct answer)
70 km/h
80 km/h
90 km/h

Correct answer: 60 km/h

Heavy goods vehicles are restricted to 60 km/h on expressways in Singapore due to their longer stopping distances and reduced manoeuvrability.

Question 20: What should you do when approaching a 'lane closed ahead' sign on the expressway?

Continue in the closing lane until the last moment
Begin merging into the open lane gradually and in good time (Correct answer)
Stop and wait for instructions
Speed up to pass before the closure

Correct answer: Begin merging into the open lane gradually and in good time

When you see a lane closure sign, begin moving to the open lane gradually. Early merging is safer and reduces congestion.

Question 21: A vehicle is exiting a driveway onto the main road. Who has right of way?

Whoever arrives first
The vehicle exiting the driveway
Vehicles and pedestrians on the main road (Correct answer)
The faster vehicle

Correct answer: Vehicles and pedestrians on the main road

Question 22: When driving through an HDB estate, why are speed humps installed?

To slow traffic and improve pedestrian safety in residential areas (Correct answer)
To damage vehicles
To mark parking boundaries
For drainage purposes

Correct answer: To slow traffic and improve pedestrian safety in residential areas

Speed humps in HDB estates are traffic calming measures designed to slow vehicles and reduce the risk of pedestrian accidents in areas with high foot traffic.

Question 23: What should you do if you are caught in the middle of a junction when the light turns red?

Wait for the next green light in the junction
Proceed and clear the junction as quickly and safely as possible (Correct answer)
Stop where you are
Reverse back behind the stop line

Correct answer: Proceed and clear the junction as quickly and safely as possible

If you are already in the junction when the light turns red, you should clear the junction as quickly and safely as possible. Never reverse.

Question 24: What do two red lights displayed at the same time at a level crossing mean?

Proceed with caution
Stop — a train is approaching or crossing (Correct answer)
Reduce speed to 20 km/h
Sound your horn and proceed

Correct answer: Stop — a train is approaching or crossing

Twin red flashing lights at a level crossing mean a train is approaching or crossing. You must stop and wait until the lights stop flashing.

Question 25: On a three-lane road in Singapore, what is the right-most lane primarily used for?

Normal driving
Heavy vehicles only
Emergency vehicles only
Overtaking only (Correct answer)

Correct answer: Overtaking only

You must not park within 9 metres before a bus stop to allow buses to pull in safely and passengers to board or alight.

Question 28: You need to exit the expressway but you are in the right lane. What should you do?

Signal and gradually move to the left lane well before the exit (Correct answer)
Stop and wait for a gap to cross
Use the emergency lane to reach the exit
Cut across all lanes to reach the exit

Correct answer: Signal and gradually move to the left lane well before the exit

Plan ahead and move to the left lane well before your exit. Cutting across multiple lanes at the last moment is extremely dangerous.

Question 29: When driving in a car park, what speed should you maintain?

Normal road speed
As fast as conditions allow
Whatever the posted limit says
No more than 15-25 km/h (Correct answer)

Correct answer: No more than 15-25 km/h

In car parks, you should drive at a very slow speed (typically 15-25 km/h) due to the presence of pedestrians, limited visibility, and reversing vehicles.

Question 30: On a wet road, how does your braking distance change compared to a dry road?

It stays the same
It can double (Correct answer)
It decreases because tyres grip better
It increases by about 10%

Correct answer: It can double

On a wet road, braking distance can approximately double because of reduced tyre grip. You should increase your following distance accordingly.

Question 31: Which of the following is a legal place to park a private car in Singapore?

In a designated HDB multi-storey car park (Correct answer)
On a clearway during off-peak hours
At a taxi stand between fares
On double yellow lines after midnight

Designated HDB car parks are legal parking areas, whereas clearways, taxi stands, and double yellow lines carry restrictions that apply at all times.

Question 32: On a road with a 50 km/h limit, can you be penalised for driving at 50 km/h if conditions are dangerous?

Yes — you must drive at a speed appropriate for conditions, even if below the limit (Correct answer)
No — you are within the speed limit
Only in designated zones
Only if an accident occurs

Correct answer: Yes — you must drive at a speed appropriate for conditions, even if below the limit

Driving at the speed limit in dangerous conditions (fog, rain, crowds) can be considered dangerous driving. You must adjust speed to conditions.

Question 33: Who has right of way at a pelican crossing when the amber light is flashing?

Pedestrians already on the crossing (Correct answer)
Cyclists
No one — first come first served
Drivers always

Correct answer: Pedestrians already on the crossing

U-turns on dual carriageways are only permitted at designated U-turn points or openings in the central divider.

Question 38: When may a driver legally park on a single yellow line?

During hours not specified on the accompanying restriction sign (Correct answer)
At any time during weekends only
Only with a valid coupon displayed
Never — it is always prohibited

Correct answer: During hours not specified on the accompanying restriction sign

A single yellow line allows parking outside the hours specified on the nearby restriction sign, so parking is legal at other times.

Question 39: What does the Green Man Countdown Timer help pedestrians with?

Calculating the traffic speed
Knowing how long until the green man appears
Seeing how much time remains to complete their crossing (Correct answer)
Determining which direction to cross
