RR-004 — Following Distance Rule
Question
In good conditions, what is the safest way to judge a following distance behind the vehicle ahead?
A. Keep a time gap of at least two seconds B. Stay exactly 50 metres behind at all times C. Keep one car length behind regardless of speed
Correct answer: A
Explanation
A time-based gap (the two-second rule) is correct because the safe distance grows automatically with speed. A fixed metre distance or ‘one car length’ does not scale with speed and is unsafe at higher speeds.
