Risks and Outcomes
Speeding includes travelling above the speed limit as well as driving too fast for the conditions, and these are major contributors to both the number and severity of crashes.
As a vehicle's speed increases, so does the time it takes for the vehicle to come to a stop. Combined with the fact that the higher the speed, the greater the impact, it becomes clear how a small increase in speed can make a big difference in the seriousness of a crash.
It's not only drivers and passengers that are affected. In fact, other road users such as pedestrians, cyclists and motorcyclists are more vulnerable and therefore more susceptible to death or serious injury if struck by a moving vehicle.
Studies show that small increases in speed can have large increases in the level of injury or the likelihood of death. Equally though, small decreases in speed can significantly reduce the severity of injuries to the vulnerable human, or avoid the crash in the first place.
