DTT Risk Perception 2

Question 1

You notice that the car ahead is weaving slightly within its lane on a rural road. What should you do?

Accepted Answer

Increase your following distance, do not attempt to overtake, and be prepared for unpredictable movements from that driver

Answer

Weaving can indicate a distracted, fatigued, or impaired driver. Increase your following distance to give yourself more reaction time, avoid overtaking as the driver's movements are unpredictable, and consider pulling over to create distance.

Question 2

What is the greatest risk when driving through a flooded section of road?

Accepted Answer

The water may be deeper than it appears, causing the engine to stall or the car to be swept away

Answer

Flooding poses severe risks: the depth may be hidden, fast-flowing water can sweep a vehicle away, water ingestion can destroy the engine, and brakes become less effective when wet. Just 30 cm of flowing water can move a car. If in doubt, do not drive through.

Question 3

Why should you be particularly cautious when driving past parked vehicles in an urban area?

Accepted Answer

Doors may open suddenly, pedestrians may step out from between vehicles, and vehicles may pull out without warning

Answer

Parked vehicles create multiple hazards: doors opening suddenly (dooring), pedestrians — especially children — stepping out from between vehicles, drivers pulling out without checking mirrors, and reduced visibility of the road ahead.

Question 4

You are approaching a green traffic light that has been green for some time. What should you consider?

Accepted Answer

The light may change to amber soon; be prepared to stop safely rather than accelerate through

Answer

A 'stale' green light that has been green for a while is likely to change soon. Be prepared to stop safely rather than rushing through. Check your mirrors for following traffic, cover the brake, and be ready to stop if the light changes to amber.

Question 5

What is 'target fixation' and why is it dangerous?

Accepted Answer

The tendency to steer towards whatever you are looking at; dangerous because if you focus on a hazard, you may drive into it

Answer

Target fixation is a natural tendency where your vehicle follows your gaze. If you fixate on a hazard (tree, wall, oncoming vehicle), you tend to steer towards it. The solution is to look where you want to go, not at what you want to avoid.
