Research shows that even a small decrease in speed significantly reduces the likelihood of a crash. If a crash does occur, slower speeds limit the severity of injuries. According to the Monash University Accident Research Centre, reducing speed by 11 per cent would reduce road deaths by 40 per cent.
Several factors increase the risk and severity of crashing when speeding. These include:
Research has shown that:
Types of speeding
All types of speeding are dangerous and place drivers and pedestrians at risk.
Speeding can be divided into three categories:
Research shows that the majority of motorists engage in low-level speeding, where the driver travels at a speed marginally over the posted speed limit, typically by around 5 km/h.
Even speeding at 5 km/h above the speed limit increases both the likelihood of a crash occurring and the severity of driver and pedestrian injuries in the event of a crash. Be aware of the speed limit at all times and monitor your speed accordingly.
In difficult driving conditions, certain speeds, even within the legal limits, may be inappropriate. Wet weather and other influences may mean that driving at the speed limit is inappropriate and dangerous. Be aware of conditions altering your vehicles response time and stopping distances, and adjust your speed accordingly.
In certain cases drivers deliberately exceed the speed limit. Doubling your speed requires four times the distance to stop.
