45mph during wet weather
You were driving at 45 mph in the wet, and so you hit the pedestrian.
The excessive speed increased both your thinking distance and braking distance. The wet weather reduced your grip on the road, and increased your braking distance. Both of these factors contributed towards the seriousness of the injury.
- Thinking Distance
- Braking Distance
- Overall Stopping Distance
Injury: Yes, the car hit the pedestrian.
In this scenario, most pedestrians would be injured and half would be killed. Only one in every ten would escape a serious injury.
- At this speed on a dry road, a driver who was using a mobile phone or who had been drinking, would hit the pedestrian and caused a more severe injury. Re-run the simulator, and select mobile phone use or drink driving to see how this changes the result.
- Wet weather has increased the braking distance. Re-run the simulator, and select dry weather, to see how much the braking distance decreases.
- Speed has increased the braking distance and the thinking distance. You can re-run the simulator at different speeds and see the effects of speed on the stopping distance.
