The hazard perception test is the second half of your theory test, taken straight after the multiple-choice questions. You watch short clips of driving and click when a hazard starts developing. It trips up more learners than the questions do — usually because of when they click, not whether they spot the hazard.
| Number of clips | 14 video clips |
| Scoring hazards | 15 (13 clips have one, one clip has two) |
| Points per hazard | 0–5 (earlier genuine click = more) |
| Maximum score | 75 (15 × 5) |
| Pass mark | 44 out of 75 |
| Pause / rewind / slow down | Not allowed |
| To pass the theory test overall | Pass this and the multiple-choice (43/50) in the same sitting |
After a short break following the 50 multiple-choice questions, you're shown 14 clips of everyday driving filmed from the driver's seat on UK roads. As each clip plays, you click the mouse the moment you see a hazard developing — something that would make a careful driver slow down, change direction or otherwise react. You can't pause, rewind or replay; each clip plays once and moves on.
Every developing hazard has a hidden scoring window that opens as the hazard begins and counts down. Click in the earliest band and you score the full 5 points; each band after that is worth one point less — 5, 4, 3, 2, 1 — down to 0 once the hazard has fully happened. Click before the window opens and you score nothing for that hazard.
The single most useful idea to take in: click the cause, not the effect. The cause is the moment the scene shifts toward danger — a parked car's door starting to open, a pedestrian turning toward the kerb, a vehicle edging out of a side road. The effect is the hazard fully unfolding. By the time you react to the effect, the window has usually counted down. Train yourself to click on the early movement.
You won't lose points for a single mistimed click, so a couple of deliberate clicks per clip is fine. But the system watches for cheating patterns: clicking continuously, or in a steady rhythm across a clip, scores you zero for that entire clip no matter what you spotted. The fix is simple — watch the road, and click deliberately only when something actually starts to develop.
One of the 14 clips contains two scoring hazards rather than one, and you're not told which clip it is. The two aren't necessarily related — you might click an oncoming car drifting wide early on, then a pedestrian stepping out further down the same clip. That clip is worth up to 10 points. Miss it entirely and you've lost a big chunk of your total, so keep scanning right to the end of every clip rather than relaxing after one click.
The closest practice to the real thing is official. The DVSA's Safe Driving for Life site offers a few free hazard perception practice clips that demonstrate the exact click mechanic and scoring — they're not the live test clips, but they're the only ones the DVSA itself endorses for learning the timing. Beyond that, the official DVSA app and a few well-reviewed third-party apps add volume: the more varied clips you see, the better your eye gets. Free question practice for the linked theory knowledge is on our mock tests and across every topic, and the underlying scanning skill overlaps heavily with hazard awareness questions.
Aim for several short sessions over two to three weeks rather than one long cram — reaction timing improves with spaced practice, not a single marathon the night before.
Hazard perception rewards good road sense, which comes from revision. Work through our full study plan, drill the hazard awareness topic, and take timed mock tests until you're consistently clearing the bar.
What's the pass mark? 44 out of 75. There are 15 scoring hazards at up to 5 points each.
How many clips are there? 14 clips, with 15 scoring hazards in total because one clip has two.
Will I lose points for clicking at the wrong time? Not for a single mistimed click. But continuous or patterned clicking scores zero for that clip.
Can I retake just this part if I fail it? No — fail either section and the whole test fails. You retake both and pay the £23 fee again, so it's worth getting right first time. See how to book and common mistakes to avoid.
