DGT Defensive Driving Techniques 5

Question 1

What is 'commentary driving' and how does it support defensive driving?

Accepted Answer

Narrating road conditions aloud to stay mentally engaged and identify hazards early

Answer

Commentary driving involves verbalizing what you observe and anticipate, which forces active scanning and improves hazard identification.

Question 2

When approaching a green traffic light that has been green for a long time (a 'stale' green), a defensive driver should:

Accepted Answer

Cover the brake and prepare to stop in case the light changes to yellow or red

Answer

A light that has been green for a long time is more likely to change soon; being ready to stop prevents running a red light.

Question 3

What effect does drowsy driving have on reaction time, and what is the recommended action?

Accepted Answer

Drowsy driving impairs reaction time similarly to alcohol; pull over and rest in a safe location

Answer

Research shows drowsy driving impairs judgment and reaction time to a degree comparable with alcohol intoxication; stopping to rest is the only safe remedy.

Question 4

What is the recommended technique when driving through standing water of unknown depth?

Accepted Answer

Both B and C are correct depending on depth

Answer

If the depth is unknown or appears unsafe, avoiding the water is best; if crossing is necessary, low speed in a low gear reduces risk of stalling and loss of control.

Question 5

What does 'over-driving your headlights' mean and why is it dangerous?

Accepted Answer

Driving at a speed where your stopping distance exceeds your headlight visibility range

Answer

Over-driving headlights means you are traveling too fast to stop within the illuminated distance, leaving no reaction time for unseen obstacles.
