Explanation: • 2 seconds: No, this would be the correct distance in good weather conditions.
• 3 seconds: No, rule 126 of the Highway Code advises a 2 second gap which should be doubled in poor weather conditions.
• 5 seconds: No, rule 126 of the Highway Code advises a 2 second gap which should be doubled in poor weather conditions to 4 seconds - which would be the minimum... 5 seconds is more than the minimum.
