Hazard perception test
The car hazard perception test has 14 video clips and 15 developing hazards. A developing hazard is something that would make you change speed or direction. Click as soon as it begins developing; each hazard can score up to five points, and the car pass mark is 44 out of 75.
Practise developing hazards in your theory workspace
Watch real-road practice clips, respond to developing hazards and keep each attempt beside the rest of your theory work.
Layna uses licensed real-road practice footage and learning windows. It is not official DVSA footage or scoring.
Everything you need for this part of the test
Practise with video
Train the difference between a possible hazard and one that is developing.
Check your score
Compare a result with the official 44-out-of-75 pass mark.
Improve your timing
Learn why patterned clicking is risky and what to watch instead.
Possible does not always mean developing.
A parked car, pedestrian or cyclist may be worth watching without yet requiring action. The scoring opportunity begins when something changes and you would need to slow, steer or alter your road position.
