Zorluk: KolayAdjusting Margins in Wet Weather

You are following another vehicle on a wet road. Under normal dry conditions, you would leave a gap of at least two seconds. What is the minimum time gap you should maintain behind the vehicle in wet conditions?

  1. A
    At least 2 seconds
  2. At least 4 secondsCevap
  3. C
    At least 10 seconds
  4. D
    At least 1 second

Cevap

At least 4 seconds
On wet roads, surface water reduces tyre adhesion, which doubles overall stopping distance. According to The Highway Code, drivers must double their normal separation distance from two seconds to at least four seconds.

Adım Adım Çözüm

1
Identify the base separation rule for good, dry road conditions.
The baseline separation gap is at least 2 seconds (the two-second rule).
This baseline provides adequate thinking and braking distance when tyre grip is optimal.
2
Apply the wet weather multiplier to the separation time.
2 seconds multiplied by 2 equals at least 4 seconds.
Because water on the road surface reduces friction and doubles overall stopping distance, the safety buffer must be doubled.
