Common theory questions

What is the stopping distance if you are driving at 30 km/h?

If you are driving at 30 km/h the braking distance – in ideal conditions – is 13.5 metres.

Stopping distances in ideal conditions:

  • 30 km/h: 13.5 metres
  • 50 km/h: 27.5 metres
  • 70 km/h: 45.5 metres
  • 90 km/h: 67.5 metres
  • 110 km/h: 93.5 metres

If the reaction time is longer than the average (one second) and/or if the braking occurs in other than ideal conditions, the stopping distance can be many times greater.
