The hazard perception test is the second part of the car theory test. It checks that you notice developing hazards early, as an experienced driver would. It is a different skill from the multiple-choice questions, so it needs its own practice.
How it works
- 14 video clips filmed from a driver's point of view, showing everyday roads.
- Each clip has at least one developing hazard; one clip has two. That makes 15 hazards.
- A developing hazard is something that would make you take action, such as slowing down or changing direction. A parked car is a hazard; a parked car whose door starts to open, or that starts to pull out, is a developing hazard.
- You click the mouse when you see a hazard starting to develop. The earlier you click within the scoring window, the more points: up to 5 points per hazard.
- Pass mark: 44 out of 75.
- You get one attempt at each clip and cannot go back.
Clicking: the rules that matter
- You do not lose points for a click at the wrong time.
- But if you click continuously or in a pattern, the clip scores zero. The test detects this.
- A safe habit: click once when you first notice something that might become a hazard, and again when it clearly starts to develop. That covers the scoring window without looking like a pattern.
How to practise
- Use the official practice clips. DVSA's own theory and hazard perception app and the official practice material use the same style of clips.
- Name the hazard out loud. As you watch, say what you see: "parked van, someone might step out", "cyclist ahead, may move out". This trains early noticing.
- Watch for clues, not just moving things: brake lights, a ball in the road, a bus at a stop, a junction with a car waiting, children near a school, a horse rider.
- Practise on real roads as a passenger. Spot hazards before the driver reacts to them.
- Do several full sets of 14 clips before the test, so the pace feels normal.
On the day
After the multiple-choice part you get a break of up to 3 minutes, then a short video explains the hazard perception part before it starts. Remember that you must pass both parts at the same sitting: if you pass the questions but fail hazard perception, you take the whole theory test again.
