Safety margins
On a motorway in good, dry conditions, what is the smallest safe time gap to keep behind the vehicle in front?
- Half a second
- At least two secondsCorrect
- At least six seconds
- One car length only
Why?
Rule 126 of The Highway Code applies the two-second rule on faster roads, including motorways, in good conditions. On these high-speed roads a two-second gap still represents a long distance, so never let it drop below that.
