Safety margins
On a dry road, how can you check you are keeping a safe distance from the car in front?
- Stay one car length behind for every 10 mph
- Leave at least a two-second time gapCorrect
- Keep about half a second behind
- Stay close enough to read its number plate
Why?
Rule 126 of The Highway Code recommends the two-second rule in good conditions: leave at least a two-second time gap between you and the vehicle in front. In wet weather this gap should be at least doubled to four seconds.
