What Is the Stopping Distance at 20 mph?
The stopping distance at 20 mph is 12 metres (40 feet).
This figure comes from the UK Highway Code and is made up of:
- Thinking Distance: 6 metres
- Braking Distance: 6 metres
- Total Stopping Distance: 12 metres
What Does a Stopping Distance of 12 Metres Mean?
A stopping distance of 12 metres means that after spotting a hazard, a vehicle travelling at 20 mph will typically travel 12 metres before coming to a complete stop.
This includes the distance travelled while the driver reacts to the hazard and the distance travelled while the brakes are slowing the vehicle.

How Far Is 12 Metres?
Many drivers underestimate how far 12 metres is.
Twelve metres is approximately:
- Three average family cars parked end to end
- The length of a large bus
- Around 40 feet
Even at a relatively low speed of 20 mph, a vehicle cannot stop instantly.
Why Is the Stopping Distance at 20 mph Important?
Understanding the stopping distance at 20 mph helps drivers appreciate how much road space is needed to stop safely.
Many residential streets, school zones and urban areas use 20 mph speed limits because lower speeds reduce the distance required to stop.
