Hazard perception test: what to expect and how to pass

In order to pass the full driving theory test, the hazard perception test must be passed alongside the multiple-choice question section.  The hazard perception test is taken immediately after the multiple choice question section, and the two parts cannot be taken separately.
The hazard perception test has been a component of the driving theory test since 2002, with an average pass rate of about 85 per cent. The hazard perception test is in place to test a driver’s awareness of hazards that can develop when driving on the road, and how they react to them via a series of video clips.

Hazard perception test: how it works

At the beginning of the test, candidates are shown a video clip about how the test works, but it’s a good idea to get your head around this before you get to the test centre. There are plenty of practice hazard perception tests available online.  
The test itself consists of fourteen, one-minute computer-generated video clips which feature road scenes you can expect during everyday driving, with at least one developing hazard – something that will cause you to take some form of action (for example changing direction or speed). There’s one clip in the test that will feature two hazards.
The method of measuring awareness and reaction to potential hazards is based on the candidate clicking a computer mouse for every hazard they recognise. Don’t go thinking you can get away with being click-happy, though.
