20mph while using a phone during dry weather
You were using a mobile phone, and so you hit the pedestrian. Even though you were driving at 20 mph, using a mobile phone distracted you and increased your thinking distance. This meant that you were not able to stop safely when the pedestrian stepped out unexpectedly.
- Thinking Distance
- Braking Distance
- Overall Stopping Distance
Injury: Yes, the car hit the pedestrian.
In this scenario, it is likely that half of the pedestrians hit would be injured, and 1 in 10 would be seriously injured or hospitalised.
- This accident would have been prevented if the driver had not been using a mobile phone. The driver took longer to spot and react to the pedestrian, because s/he was distracted by the mobile phone. This resulted in a longer thinking distance, which meant that it took longer to stop. Re-run the simulator, without selecting mobile phone use, to see how the thinking distance is reduced, and how this changes the result.
- Drinking alcohol also increases the thinking distance meaning that the driver takes longer to spot and react to the pedestrian. Re-run the simulator, and select alcoholic impairment instead of mobile phone use, to see how this changes the result.
- Wet weather increases braking distances. Re-run the simulator, and select wet weather, to see how much the braking distance is increased and how this changes the result.
