Hazard perception test explained

Hazard perception test is the hardest part of the theory test. Hazard perception test evaluates how well a learner driver is able to spot and react to a hazardous situation. Detecting a potential hazard early enough is an important skill that all drivers should have. Good hazard perception skills helps prevent road accidents and save lives.


What is the Hazard Perception test?

Learners will watch fourteen one minute long hazard perception test video clips (nineteen clips for lorry and bus candidates). Clips are computer generated imagery (CGI) and filmed from the perspective of a passenger car driver. Learners have to indicate, usually by clicking a mouse button or touching the screen, when they observe a developing hazard. All of the clips will include one developing hazard, and one will include 2 hazards. The sooner the student reacts to a developing hazard, the more points are scored. Points are from five down to one, with no score if the examinee reacts too late.

Hazard perception CGI

What does "hazard perception CGI" mean? CGI comes from Computer-Generated Imagery. CGI clips replaced the old filmed hazard clips in the hazard perception part of the theory test. The reason why they changed filmed clips to CGI clips was that the image quality wasn’t clear enough.

These new CGI clips looks clearer than the old ones. Even the clips are now CGI, there are no other changes in the test.
