What is the hazard perception test?
The hazard perception test is the second part of the driving theory test. It uses video clips filmed from a driver's perspective to measure how quickly and accurately you can spot developing hazards on the road. You must score at least 44 out of 75 to pass — and you must pass both parts of the theory test on the same day.
How does it work?
You will watch 14 video clips, each about one minute long. Thirteen clips contain one scoreable hazard and one clip contains two scoreable hazards, giving a maximum possible score of 75. You score points by clicking as soon as you see a hazard developing. The earlier you click (within the scoring window), the more points you earn — up to a maximum of five per hazard.
Developing Hazards
A developing hazard is one that causes you to change speed or direction. Look for pedestrians stepping out, vehicles pulling out and junctions.
Scoring System
Each hazard has a window of opportunity. Click early in the window to score five points; clicking later scores fewer. Missing the window scores zero.
Pass Mark
You need at least 44 out of 75 to pass the hazard perception element. There is no pass mark per clip — your total across all 14 clips is what counts.
Avoid Click Patterns
Do not click repeatedly or in a pattern — the system detects this and may award you zero for that clip. Click only when you genuinely see a hazard.
14 Video Clips
Clips show real-world driving scenarios in all conditions — town roads, rural roads, motorways and dual carriageways.
Practice & Preparation
Regular practice with hazard perception clips is the most effective way to improve your reaction time and score.
Top tips for the hazard perception test
Focus on the road ahead and anticipate what might happen next. Look for clues — a ball rolling into the road often signals a child following it; a junction ahead may hide a vehicle about to pull out. With practice, your reaction times improve naturally. The Learn to Drive with RED app includes hazard perception practice clips to help you get test-ready.
