As your speed increases:

  • the distance you need to stop increases
  • you have less time to react
  • there is a greater chance that other road users will misjudge how fast you are travelling.

The severity of injuries resulting from a crash are directly related to the impact speed of the vehicle – whether or not speeding was a factor in the crash.

Your speed will impact the time you have to react if someone else makes a mistake.

What can you do to reduce the risk?

  • Travel within the speed limit and judge the safest speed for the stretch of road you are driving
  • Traffic conditions that you might need to reduce your speed for include:
    • high volumes of traffic on the road
    • pedestrians, joggers and cyclists
    • holiday times where there are lots of visitors on the road
    • parked cars
  • Road conditions you should reduce your speed for include:
    • bumpy or narrow areas of road
    • wet, icy or gravel road surfaces
    • signs warning of hazards such as sharp curves or a slippery surface
  • Weather conditions you should reduce your speed for include:
    • rain, snow and ice
    • wind
    • fog
    • bright sunlight
