Crashing at speed


It’s simple – the faster you travel, the less time you have to react to emergencies or to stop. And if you do crash, the faster you are travelling, even if within the speed limit, the greater the risk of injury to you and your passengers.

The risk of being involved in a crash resulting in injury in a 60 km/h speed zone doubles with every 5 km/h increase in driving speed above the limit. This means travelling at 65 km/h in a 60 km/h speed zone doubles the chance of having a crash resulting in injury. Travelling at 70 km/h increases the chance of crashing by 4 times and travelling at 80 km/h increases this chance by 32 times.

This is due to kinetic energy, which a person or object has while it is moving. This energy is gained during acceleration and lost during deceleration. In a collision, the energy is transferred to the other person or object, usually as sound, heat and deformation of objects, including the human occupants.


We're watching your speed. Are you?

With police and speed cameras ever present on our roads, it's like there's a cop in every car keeping constant eye on your speed. More police. More cameras.

Stopping distances

Reaction distance is the distance you travel between seeing a problem and hitting the brakes. If you’re not distracted you’ll react in 1.5 seconds. if you’re doing 60km/h, you’ll still travel 25 metres in the time it takes for the message to get from your brain to your foot.

Braking distance is the number of metres you travel between hitting the brakes and coming to a complete stop. You’ll cover another 20 metres before this happens, assuming you’re driving on a dry road, in a newer car with good tyres and brakes.

Stopping distance is the distance when you add your reaction distance to your braking distance. If you’re doing 60km/h, you should come with 45 metres. If you are speeding, it is easy to see that 5km/hr over the speed limit, will greatly impact your ability to brake in time to avoid a crash. The stopping distance due to speeding could be the difference between someone escaping with little more than a scare and a pedestrian losing their life.

Speeding penalties & speed camera locations

In Western Australia, 100% of all red light and speed camera infringements go into the Road Trauma Trust Account (RTTA).
Those funds are then allocated to improve road safety across the state.

The Road Safety Commission supports public access to the locations of speed cameras around Western Australia.
