How Does the Hazard Perception Test Work?

Hazard perception is the second part of the car theory test. It checks whether you can spot developing hazards early.

The format

• 14 video clips filmed from a driver's point of view.
• Each clip has at least one developing hazard; one clip has two.
• That makes 15 scoreable hazards, worth up to 5 points each, so 75 in total.
• The pass mark is 44 out of 75.

What is a developing hazard?

A developing hazard is something that would make you take action, such as slowing down, stopping or changing direction.

A parked car is a potential hazard. A parked car whose indicator comes on and starts to pull out is a developing hazard.

How scoring works

The sooner you respond once the hazard starts developing, the more points you score, from 5 down to 1. Clicking before the scoring window starts earns nothing for that click, so it's sensible to click again as the hazard develops.

Important: If you click continuously or in a pattern, you'll score zero for that clip.

Tips

• Scan the whole scene: pavements, junctions, mirrors of parked cars.
• Look for clues: brake lights, children near the road, cyclists, horse riders, bus stops.
• Click when you first notice a change, then once more as it develops.
• Practise with official clips so you get used to the format.

Make it practical

Ask your instructor to talk through hazards during lessons. Real-world scanning skills carry over directly. Find a driving instructor.
