Hazard perception clips get a modern makeover using CGI


New computer-generated imagery (CGI) clips replaced old filmed clips in the hazard perception part of the theory test on 12 January 2015. The test was made up of filmed video clips which showed everyday road scenes. Those clips were still relevant, but the image quality wasn’t as clear or defined as modern technology allows.

Differences in the new clips

The new clips show the same situations as the previous clips, but they:

  • look clearer on the screen
  • include updated vehicles, roads and surroundings so they look modern

No change to how the test works

The way that the hazard perception part of the theory test works hasn’t changed. The pass mark of 44 out of 75 has stayed the same for car and motorcycle with 14 clips.

The clips:

  • feature everyday road scenes
  • contain at least one ‘developing hazard’ – but one of the clips will feature 2 ‘developing hazards’

A developing hazard is something that may result in you having to take some action, like changing speed or direction.
