In good conditions on an open tarred road, a safe gap behind the vehicle in front is about:
- About 10 metres at any speed
- ✓ One metre for every km/h of your speed
- Half a metre for every km/h
- One car length for every 10 km/h
Correct answer : One metre for every km/h of your speed
Why : A gap of one metre for each km/h of your speed may be enough (60 m at 60 km/h); much more on wet or earth roads.
