Speed checks
About this service
Two-thirds of all crashes in which people are killed or injured happen on roads with a speed limit of 30mph or less. At 35mph a driver is twice as likely to kill someone as they are at 30mph.
- Hit by a car at 40mph, 8 out of 10 pedestrians will be killed
- Hit by a car at 30mph, around 80 per cent of pedestrians will survive
- Hit by a car at 20mph, only 1 out of 10 pedestrians will be killed
Crash risk rises the faster a driver travels. At 25 per cent above the speed, a driver is about six times more likely to have an accident than a driver travelling at the posted limit.
At 30mph, vehicles travel 44 feet (about three car lengths) every second. Even in good conditions, the difference in stopping distance between 30mph and 35mph could be as much as an extra 21 feet - more than two car lengths.
