On average, 9 people die and 100 people are seriously injured on Great Britain's roads each day.

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, 9 out of 10 pedestrians will be killed
Hit by a car at 30mph, around 50 per cent of pedestrians will survive
Hit by a car at 20mph, only 1 out of 10 pedestrians will be killed

Collision risk rises the faster a driver travels. At 25 per cent above the average speed, a driver is about six times more likely to have a collision than a driver travelling at the average speed.

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 is an extra 21 feet - more than two car lengths.

The Casualty Reduction Partnership aims to achieve greater compliance with speed limits by:

- raising awareness of the hazards of speeding
- increasing knowledge of national speed limits
- ensuring that speed limits are appropriate for the road conditions
- ensuring that speed limits are appropriately signed
- enforcing speed limits, especially in areas of community concern and at collision trouble-spots
