Zorluk: KolaySeparation Distances and the Two-Second Rule

You are driving a car along a dual carriageway in wet weather. According to the UK Highway Code, what is the minimum separation time gap, in seconds, you should maintain between your car and the vehicle travelling ahead?

Cevap: 4 seconds

Cevap

4 seconds
According to the UK Highway Code (Rule 126), drivers should maintain at least a 2-second time gap in normal dry conditions. In wet weather, stopping distances are at least double those on dry roads, meaning the separation gap must be increased to at least 4 seconds.

Adım Adım Çözüm

1
Identify the standard baseline time separation gap for good, dry road conditions.
The baseline separation time gap is 2 seconds.
The UK Highway Code establishes the 'two-second rule' as the safe minimum following gap under normal dry conditions.
2
Apply the wet weather multiplier to the baseline time gap.
Double the baseline gap: 2 seconds × 2 = 4 seconds.
Wet road surfaces reduce tyre friction and double overall stopping distances, requiring drivers to double the separation gap to at least 4 seconds.
