Speed and Accident risk

Interesting facts from Roads and Traffic Authority of New South Wales:

Speeding increases the risk of a crash and the severity of the crash.

The risk of a crash in an urban 60 km/h speed zone causing death or injury increases rapidly even with relatively small increases of speed. The accident risk at 65 km/h is about twice the risk at 60 km/h. At 70 km/h the accident risk is more than four times the risk at 60 km/h.

Speed – km/h Accident risk relative to 60 km/h
65 Double
70 4 times
75 11 times
80 32 times

The risk of a crash at 68 km/h in a 60 km/h zone is the same as driving with a blood alcohol level of 0.08. The risk at 72 km/h in a 60 km/h zone is the same as driving with a blood alcohol level of 0.12 – more than double the general legal limit.

A key issue in speeding-related crashes is the fact that most motorists underestimate the distance needed to stop. A car travelling at 60 km/h in dry conditions takes about 38 metres to stop. A car travelling at 72 km/h needs an extra 12 metres.
