Hazard Perception Test

What is Hazard Perception?

The hazard perception test is the second part of the UK driving theory test. You watch 14 video clips of real driving scenarios filmed from a driver's point of view. Each clip contains at least one developing hazard, and one clip has two developing hazards. Your task is to click the mouse as soon as you see a hazard developing.

How Scoring Works

Each hazard has a scoring window divided into 5 bands. The earlier you spot the developing hazard, the higher your score:

• 5 points — earliest response in the scoring window
• 4 points — slightly later
• 3 points — middle of the window
• 2 points — later
• 1 point — latest acceptable response
• 0 points — responded too late or not at all

The maximum score is 75 (15 hazards × 5 points). The pass mark is 44 out of 75.

Tips to Pass

• Click as soon as you see a hazard starting to develop — don't wait
• A developing hazard is something that would cause you to change speed or direction
• Don't click in a random pattern — the system can detect this and score you zero
• Watch the whole clip — hazards can appear at any point
• Look for pedestrians, cyclists, vehicles at junctions, and road conditions
• Remember one clip will have two hazards — stay alert throughout
