Stopping Distances


Speed and Stopping Distances

Drivers who travel at higher speeds have less time to identify and react to what is happening around them. It takes them longer to stop. And if there is a crash, it is more severe, causing greater injury to the occupants and any pedestrian or rider they hit.

This short factsheet provides further information about speeding and tips to help drivers avoid creeping over the limit unintentionally.

Mobile Phones and Stopping Distances

Drivers who use a mobile phone, whether hand-held or hands-free, are much less aware of what’s happening on the road around them, see road signs, warnings, and hazards later (or not at all), react more slowly and take longer to brake. This can easily turn a near miss into a serious crash.

This short factsheet explains why and how using a mobile phone when driving is dangerous.

Drink-driving and Stopping Distances

Alcohol impairs judgement, making drivers over-confident and more likely to take risks. It slows their reactions, increases stopping distances, affects judgement of speed and distance and reduces their field of vision. Even a small amount, well below the legal limit, seriously affects the ability to drive safely. Drinking and driving is illegal and significantly increases the chances of crashing.

This short factsheet provides information about the dangers and consequences of drink driving.

Wet Weather and Stopping Distances

It takes longer to stop on wet roads because the friction between the car's tyres and the road surface is reduced. This increases the car’s braking distance, especially when a vehicle's tyres have less than 3mm tread depth. This can easily turn a near miss into a serious crash.

This factsheet gives advice and information about driving in wet weather.
