In the real DVSA hazard perception test, you watch video clips showing everyday road scenes and click when you spot a developing hazard. A developing hazard is something that would make you take action, such as slowing down, stopping, or changing direction.
You score points based on how early you react as the hazard starts to develop. Each developing hazard is worth up to 5 points. One clip contains 2 developing hazards.
Top tip: you're not trying to click everything you can see. Click calmly and don't click in a rhythm or pattern.
For the DVSA HGV / LGV hazard perception test, you'll watch 19 clips in total. Across the test there are 20 developing hazards (one clip contains 2 hazards).
To pass the hazard perception part, you need at least 67 out of 100.
Top tip: if you're unsure, use a calm 'two-click' approach - one click when you first see it developing and a second click a moment later if it continues. This can help you catch the scoring window without over-clicking.
