DTT Hazard Awareness

Question 1

What is the primary purpose of hazard perception in driving?

Accepted Answer

To identify potential dangers early and take action to avoid them

Answer

Hazard perception is about scanning the road environment continuously to identify developing hazards early, giving you more time to react and take appropriate action to avoid collisions or dangerous situations.

Question 2

You are driving on a residential street and see a ball rolling onto the road from behind a parked car. What hazard should you anticipate?

Accepted Answer

A child may follow the ball onto the road

Answer

A ball rolling onto the road is a classic predictor that a child may follow it without looking for traffic. You should immediately slow down, cover the brake, and be prepared to stop, especially in residential areas.

Question 3

When driving in heavy rain, your stopping distance compared to dry conditions is approximately:

Accepted Answer

Doubled

Answer

In wet conditions, stopping distances are approximately doubled because tyres have less grip on wet road surfaces. This means you should at least double your following distance and reduce speed.

Question 4

What is aquaplaning and what should you do if it occurs?

Accepted Answer

When tyres lose contact with the road surface due to a layer of water; ease off the accelerator and do not brake sharply or steer suddenly

Answer

Aquaplaning occurs when a layer of water builds up between the tyres and road surface, causing loss of traction and steering control. If it happens, ease off the accelerator gently, hold the steering wheel straight, and avoid sudden braking or steering inputs.

Question 5

You notice a lorry ahead indicating to change lanes on a motorway. What hazard should you be aware of?

Accepted Answer

The lorry has large blind spots and the driver may not have seen you; give it plenty of space

Answer

Large vehicles have significant blind spots (areas the driver cannot see in mirrors). When a lorry indicates, maintain awareness that the driver may not see you, give it space, and be prepared for it to move into your lane.
