The hazard perception test explained (and how to practise free)

The hazard perception test is the part people understand least, and it is where a lot of otherwise well-prepared learners fail. Here is exactly how it works and how to get good at it.

What it is

After the multiple-choice questions, you watch 14 short video clips filmed from a driving seat. In each clip you click the mouse (or tap) the moment you see a hazard starting to develop - something that would make you slow down or change direction, like a car pulling out or a pedestrian stepping off the kerb.

How the scoring works

• There are 15 scoring hazards across the 14 clips (one clip has two).
• Each hazard is worth up to 5 points. The earlier you spot it as it develops, the more points you score.
• The pass mark is 44 out of 75.

The mistake that scores zero

You cannot just click constantly to be safe. The system detects a steady pattern of clicking and gives that clip zero. The trick is to click once or twice as a genuine hazard develops, then stop. Watch, react, click - do not spam.

How to get better

• Learn what "developing" means. A parked car is just there; a parked car whose brake lights come on is developing into a hazard. Click as it changes.
• Practise the timing. The clicking feels strange at first. A few practice sessions makes it natural.
• Watch the whole scene, not just the centre of the road - hazards come from the pavement, side roads and parked cars.

The official free practice only gives you a few clips, and most apps lock the rest behind a paywall. We think hazard perception practice should be easy to get to - it is the part people most need help with.
