Fast driving is a major cause of road crashes. The faster you drive a car the longer it will take you to stop. The faster you hit something, the greater the effect of the impact. If you’re driving at 35mph, you’re twice as likely to kill someone than you are at 30mph.
What is a speed limit?
A speed limit is the maximum speed at which you can drive. However you have to use your common sense as the speed limit isn’t always a safe speed. Driving too fast doesn’t always mean going over the speed limit.
It can mean driving at a speed that’s not safe for the road conditions. For example, driving at 30mph along a busy shopping street with lots of people around is too fast.
The 20mph limit
Because of this problem, the 20mph limit is being used more and more in built up areas, especially around schools and on residential streets. It should be noted however, that even 20mph can be too fast in certain circumstances.
