Hazard perception is sat at the same appointment as the multiple-choice questions, and you must pass both parts in one sitting to pass the theory test. Car drivers and motorcyclists watch 14 clips containing 15 developing hazards and need 44 points out of 75 to pass. Lorry and bus candidates watch 19 clips with 20 hazards and need 67 out of 100, while trainee driving instructors face the same clips as learners but must reach the higher mark of 57 out of 75.

What counts as a developing hazard

A developing hazard is anything that would make you slow down, brake or change direction — a car door opening into your path, a cyclist drifting out to pass a drain, a van edging out of a side road. Parked cars, pedestrians on the pavement and oncoming traffic are only potential hazards until they start to move, and learning to spot the moment one becomes the other is the whole skill this test measures.

How to use this library

Work through the clips in order and treat each one as a mini test: watch, respond, then compare your timing with the moment the hazard first began to develop. The free clips let you learn the technique before committing to the full library, and returning to earlier clips after a few days is a quick way to confirm the skill has stuck rather than the clip being memorised.

Building the habit on real roads

Hazard perception improves fastest when screen practice is backed up by commentary on real journeys, whether you are driving, riding or a passenger. Say out loud what you can see developing ahead — brake lights, school signs, a bus waiting at a stop — and the on-screen clips will soon start to feel slow by comparison.
