Hazard perception
Hazard perception is part of the UK theory test for car, motorcycle, lorry and bus drivers. You watch video clips from the driver seat and respond as hazards develop, before the multiple choice result counts.
The real format
- A test is 14 clips. You score up to 5 points for each hazard, depending on how early you respond.
- One clip in every test has two hazards, so the maximum score is 75 points.
- You pass hazard perception with 44 points or more.
- Responding in a pattern, clicking repeatedly or in a regular rhythm, scores zero for that clip.
