Zorluk: KolayAdjusting Margins in Wet Weather

You are driving on a rural road behind another car during steady rain. What is the minimum time gap you should maintain between your vehicle and the car ahead?

  1. A
    At least one second
  2. B
    At least two seconds
  3. At least four secondsCevap
  4. D
    At least ten seconds

Cevap

At least four seconds
In good, dry conditions, drivers should leave a minimum gap of two seconds from the vehicle in front. In wet weather, tyre adhesion is significantly reduced and stopping distance increases, so the Highway Code requires drivers to double this margin to at least four seconds.

Adım Adım Çözüm

1
Identify the standard separation distance rule for dry roads
In normal, dry conditions, the safe following margin is at least two seconds.
The two-second rule provides sufficient thinking and braking distance under good tyre-to-road adhesion.
2
Apply the wet weather adjustment rule from the Highway Code
Double the standard time gap, resulting in at least four seconds.
Water lowers surface friction and increases braking distance, requiring double the separation buffer.

Anahtar Kavram

Separation margins must be doubled from two to at least four seconds on wet roads.
