How many hazard perception clips are in the theory test?

Quick answer

• The car hazard perception test has 14 video clips.
• There are 15 scoreable developing hazards in total.
• One clip contains two developing hazards.
• Each developing hazard can score up to 5 points.

For the UK car theory test, the hazard perception section contains 14 video clips. Most clips have one developing hazard, but one clip has two. That means there are 15 scoreable developing hazards in total.

Why the number of clips matters

Fourteen clips is enough for patterns to matter. You cannot rely on one lucky clip or one type of hazard. You need to stay alert across different roads, speeds, road users, weather, and traffic situations.

• Some hazards develop slowly, such as a pedestrian approaching a crossing.
• Some develop quickly, such as a vehicle emerging from a side road.
• Some are partly hidden, such as activity near parked vehicles.
• One clip will expect you to identify two developing hazards.

How are the clips scored?

Each scoreable developing hazard has a scoring window. Clicking earlier in the correct window scores more marks, up to 5. Clicking too late scores fewer marks, and missing the hazard scores nothing for that hazard.

The test can score a clip as zero if you click continuously or in a pattern that looks like guessing. Click when you genuinely identify a developing hazard.

How should you practise 14 clips?

1. Watch actively

   Scan the full scene rather than staring at the vehicle directly ahead.

2. Name the risk

   Say what might happen next: pedestrian steps out, car pulls away, cyclist moves right.

3. Review misses

   If you clicked late, work out which early clue you ignored.
