hazard perception

What is the Hazard Perception?

The hazard perception test is the second part of the theory test and follows the multiple-choice questions. After the multiple-choice exam, you can take a break of up to three minutes before the hazard perception test begins. First, you’ll be shown a tutorial video featuring sample footage with a commentary that explains how to complete the test. You’ll be given the opportunity to watch the tutorial a second time if you need to.

What can I expect in the hazard perception test?

The test is made up of 14 one-minute video clips, which feature various hazards such as vehicles, pedestrians and road conditions. You have to presume you’re a driver as these clips are played, and you respond to each scenario by clicking your mouse as soon as you see a hazard developing. The earlier you spot the hazard and click the mouse, the higher your score.

The highest score possible for each developing hazard is five points, but it’s no good just constantly clicking the mouse whenever you feel like it, as the system is designed to detect this. Just sitting there clicking like mad will lead to a message telling you that you’ve scored zero for that particular clip.

Your results

After you’ve finished both parts of the theory test, you’ll be given your results. For the multiple-choice part, the pass mark is 43 out of 50 and for the hazard perception test, the pass mark is 44 out of a possible 75.

You need to pass both parts of the test at the same session to pass your theory test. Your test pass is valid for two years, during which you’ll need to pass your practical test. If you fail the theory test, you can retake it after waiting at least three working days, and there’s no limit to the number of times you can retake it.
