Speed & Following Distance — BTT Practice Questions

Q: Unless otherwise stated, The speed limit of all roads in Singapore is:

50km/h. The default road speed limit is 50 km/h unless a sign states another limit. A lower limit may still be necessary when traffic, weather or visibility makes 50 km/h unsafe.

Q: Which of the following can be taken as a rule of thumb to avoid tail-gating?

The Two-Second rule.. Use the two-second rule to check a safe following gap in good conditions. Increase the gap substantially in rain, poor visibility or other conditions that lengthen stopping distance.

Q: What might be the consequence of tailgating?

The behind vehicle might crash into the front vehicle.. Tailgating leaves too little time and distance to react when the vehicle ahead slows or stops. Keep a proper following gap to avoid a rear-end collision.

Q: Which of the following is true?

Reaction Distance = Stopping Distance - Braking Distance. Stopping distance has two parts: reaction distance travelled before braking begins, and braking distance travelled while the vehicle slows to a stop.

Q: Following another vehicle very closely behind

May lead to an accident. Keep a safe following gap; tailgating removes the time and distance needed to avoid a rear-end collision.

Q: When your vehicle is heavily loaded, the stopping distance will

Increase. A heavily loaded vehicle needs more distance to stop, so leave a larger following gap and reduce speed where necessary.

Q: 'Two-second rule' can be applied when driving at

Any speed. Use the two-second rule at any speed in good, dry conditions; its time-based method automatically increases distance as speed rises.

Q: A safe following distance is at least one car length for every ___ of your speed.

16 km/h. A traditional distance guide is at least one car length for every 16 km/h, although the two-second rule is a more reliable way to judge a gap.

Q: If the speed limit of the road is 50km/h, and the maximum speed of your vehicle is 120km/h. which of the following speed you should drive at:

45km/h. A vehicle’s capability does not override the road limit. Choose a speed within the 50 km/h limit and suitable for conditions.

Speed limits, safe following distance, the two-second rule, and braking distances.

Speed & Following Distance questions

Unless otherwise stated, The speed limit of all roads in Singapore is:

70km/h

60km/h

50km/h Correct answer

The default road speed limit is 50 km/h unless a sign states another limit. A lower limit may still be necessary when traffic, weather or visibility makes 50 km/h unsafe.

Which of the following can be taken as a rule of thumb to avoid tail-gating?

The Four-Second rule.

The Two-Second rule. Correct answer

The Three-Second rule.

Use the two-second rule to check a safe following gap in good conditions. Increase the gap substantially in rain, poor visibility or other conditions that lengthen stopping distance.

What might be the consequence of tailgating?

The front vehicle might stop suddenly.

The behind vehicle might crash into the front vehicle. Correct answer

The behind vehicle might traveled too fast.

Tailgating leaves too little time and distance to react when the vehicle ahead slows or stops. Keep a proper following gap to avoid a rear-end collision.

Which of the following is true?

Reaction Distance = Stopping Distance - Braking Distance Correct answer

Stopping Distance = Braking Distance - Reaction Distance

Braking Distance = Reaction Distance - Stopping Distance

Stopping distance has two parts: reaction distance travelled before braking begins, and braking distance travelled while the vehicle slows to a stop.

What are the consequences of tailgating?

Driver in front will drive faster

No consequences

Driver in front of you may become nervous,stop suddenly and accident might occur Correct answer

Tailgating pressures the driver ahead and removes your own stopping margin. It can lead to sudden braking and a rear-end collision.

Following another vehicle very closely behind

May lead to an accident Correct answer

Is encouraged as it gives more space to the vehicles behind

Is very safe as the visibility will be clear

Keep a safe following gap; tailgating removes the time and distance needed to avoid a rear-end collision.

When your vehicle is heavily loaded, the stopping distance will

Increase Correct answer

Decrease

Remain the same

A heavily loaded vehicle needs more distance to stop, so leave a larger following gap and reduce speed where necessary.

'Two-second rule' can be applied when driving at

High speed

Any speed Correct answer

Low speed

Use the two-second rule at any speed in good, dry conditions; its time-based method automatically increases distance as speed rises.

A safe following distance is at least one car length for every ___ of your speed.

16 km/h Correct answer

10 km/h

20 km/h

A traditional distance guide is at least one car length for every 16 km/h, although the two-second rule is a more reliable way to judge a gap.

If the speed limit of the road is 50km/h, and the maximum speed of your vehicle is 120km/h. which of the following speed you should drive at:

60km/h

45km/h Correct answer

120km/h

A vehicle’s capability does not override the road limit. Choose a speed within the 50 km/h limit and suitable for conditions.

If you are traveling at a speed of 80km/h, how many vehicle(s) length at least should be adhered to between your vehicle and the vehicle in front?

5 Correct answer

For the question "If you are traveling at a speed of 80km/h, how many vehicle(s) length at least should be adhered to between your vehicle and the vehicle in front?", the correct answer is "5" because the basic rule is to maintain at least one vehicle length for every 16km/h of your vehicle speed.
