All forms of speeding are dangerous. Speed is one of the major factors contributing to crashes. The speed at which a driver chooses to travel on the road affects both the risk of a crash occurring and the severity of resulting injuries.

Research by the Centre for Automotive Safety Research shows that on 60km/h urban roads the risk of a crash doubles when travelling just 5km/h above the speed limit.

Greater demands are placed on drivers travelling at higher speeds, because the time to respond to changing conditions on the road ahead is significantly less. Therefore the ability to react to actions of other drivers or unexpected hazards is reduced and greater distance is required to stop.

Put simply, as your speed increases, so does your risk of crashing and being seriously injured or killed or worse, injuring or killing someone else. There are no excuses for speeding.
