What is a Hazard Perception Test?
Learners will watch fourteen one minute long hazard perception test video clips (nineteen clips for lorry and bus candidates). Hazard perception 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 hazard perception 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 on 13 Jan 2015. The reason why they changed filmed clips to CGI clips was that the image quality wasn’t clear enough.
