Singapore BTT (Basic Theory Test) — Questions and Answers

Question 1: When can you drive in an emergency lane on the expressway?

Only in a genuine emergency such as a vehicle breakdown (Correct answer)
During heavy traffic
When overtaking
During off-peak hours

Correct answer: Only in a genuine emergency such as a vehicle breakdown

The emergency lane (road shoulder) may only be used for genuine emergencies such as a vehicle breakdown. Using it to beat traffic is illegal.

Question 2: A pedestrian crossing signal shows a steady red man. As a driver, what does this typically mean?

You definitely have a red light
The crossing is out of service
You have a green light — proceed with caution for jaywalkers
You may have a green light but must still watch for pedestrians (Correct answer)

Correct answer: You may have a green light but must still watch for pedestrians

When the red man shows, vehicles typically have a green light, but you must still watch for pedestrians who may be jaywalking or still finishing crossing.

Question 3: A lane on your left is ending and merging into yours. Who should give way?

Neither — both stop
You must slow down and let them in
The larger vehicle has priority
The merging vehicle must adjust speed to fit into your lane safely (Correct answer)

Correct answer: The merging vehicle must adjust speed to fit into your lane safely

The vehicle in the ending lane must adjust their speed to merge safely into the continuing lane. However, courteous drivers in the continuing lane will cooperate.

Question 4: 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 5: A bus lane has its own traffic light showing a white 'B' signal. What does a lit white 'B' mean?

All vehicles may use the bus lane
Bus lane is closed
Buses must stop
Buses may proceed (Correct answer)

Correct answer: Buses may proceed

A white 'B' signal at a bus lane gives buses priority to proceed, separate from regular traffic signals.

Question 6: What is 'weaving' in traffic, and is it legal?

Alternating between lanes in heavy traffic — it is encouraged
Using two lanes on curves — it is permitted
Driving in a zigzag pattern — it is legal on expressways
Changing lanes repeatedly to get ahead — it is illegal and dangerous (Correct answer)

Correct answer: Changing lanes repeatedly to get ahead — it is illegal and dangerous

Weaving means frequently changing lanes to gain a speed advantage. It is dangerous, increases accident risk, and can result in fines.

Question 7: You are in the left lane behind a slower vehicle. How should you overtake?

Overtake on the left using the shoulder
Check mirrors, signal right, move to the right lane, pass, then return left (Correct answer)
Flash your headlights and honk
Tailgate until they move

Correct answer: Check mirrors, signal right, move to the right lane, pass, then return left

The correct procedure is to check mirrors, signal, move to the right lane to overtake, and then signal and return to the left lane once safely past.

Question 8: What does a triangular sign with a windsock symbol warn about?

Airport nearby
Kite-flying zone
Strong crosswinds ahead (Correct answer)
Wind turbine area

Correct answer: Strong crosswinds ahead

A windsock on a warning sign indicates an area prone to strong crosswinds, which can affect vehicle stability, especially on bridges and open stretches.

Question 9: What should you do when approaching a 'lane closed ahead' sign on the expressway?

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

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

90 km/h
60 km/h (Correct answer)
80 km/h
70 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 11: A vehicle is exiting a driveway onto the main road. Who has right of way?

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

Correct answer: Vehicles and pedestrians on the main road

Vehicles and pedestrians already on the main road have right of way. The vehicle exiting the driveway must wait for a safe gap.

Question 12: When can a vehicle legally cross a double white continuous centre line?

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

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 13: At a signalised junction, the green light shows but a pedestrian is still crossing. What should you do?

Drive around the pedestrian
Wait for the pedestrian to finish crossing (Correct answer)
Proceed — you have right of way
Sound horn to hurry the pedestrian

Correct answer: Wait for the pedestrian to finish crossing

Even when you have a green light, you must always give way to pedestrians who are still on the crossing. Safety of pedestrians takes priority.

Question 14: What is a 'Silver Zone' in Singapore?

A zone for electric vehicles only
An enhanced safety zone with slower speeds for areas with many elderly residents (Correct answer)
A premium parking area

Speed up and cross quickly
Continue at the same speed
Flash your headlights and proceed
Stop, as you are at the stop line and can do so safely (Correct answer)

Correct answer: Stop, as you are at the stop line and can do so safely

If you are at or behind the stop line when the amber light appears, you should stop since you can do so safely.

Question 16: What does a white arrow on blue background pointing to the left at a roundabout mean?

Turn left only
Left lane must exit
No right turn
Keep left at the roundabout (Correct answer)

Only straight traffic may use this lane
Vehicles in this lane may either go straight or turn right (Correct answer)
The arrows are contradictory — an error

80 km/h
50 km/h
60 km/h (Correct answer)
90 km/h — same as other vehicles

Correct answer: 60 km/h

Vehicles towing trailers have a lower speed limit of 60 km/h on expressways due to the increased stopping distance and reduced manoeuvrability.

Question 19: What should you do when an ambulance approaches with sirens from any direction at a junction?

Stop and remain stationary until it passes (Correct answer)

Continue if you have a green light
Reverse to make room

To conserve fuel
Because the curve radius requires a lower speed for safe negotiation (Correct answer)
To annoy drivers
They are outdated signs

Correct answer: Because the curve radius requires a lower speed for safe negotiation

Advisory speed signs on curves and ramps indicate the safe speed for that curve's radius. Exceeding this speed risks loss of control.

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

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