Key takeaways
- The hazard perception test is a video-based part of the theory test about spotting developing hazards.
- You watch 14 clips, and one of the clips includes 2 developing hazards.
- You can score up to 5 points for each developing hazard, and the car hazard perception pass mark is 44 out of 75.
Short answer: what is the hazard perception test?
The hazard perception test is the part of the DVSA theory test where you watch video clips of road scenes and respond when you see a developing hazard.
A developing hazard is something that would cause you to take action, such as changing speed or direction.
You need to pass hazard perception as well as the multiple-choice questions to pass the theory test.

Hazard perception theory test: where it fits
The theory test has two parts: multiple-choice questions and hazard perception.
You book and take them as one theory test, and you need to pass both parts to pass overall.
The multiple-choice section checks your knowledge of rules, signs and safe driving.
The hazard perception section checks how well you can spot developing hazards in realistic road situations.

What is a developing hazard?
A developing hazard is something happening on the road that would make you take action, such as slowing down, changing direction or being ready to stop.
Examples may include:
- a pedestrian stepping towards the road
- a car starting to pull out from the side of the road
- a cyclist moving into your lane
- a vehicle braking suddenly ahead
- a child running near parked cars
- a bus pulling away from a stop
The key is that the hazard is developing. You are not just looking for something that exists; you are looking for the moment it begins to affect what you would do as a driver or rider.
How many hazard perception clips are there?
In the car theory test, you watch 14 hazard perception video clips.
The clips show everyday road scenes. Each clip contains at least one developing hazard, and one of the clips contains two developing hazards.
You only get one attempt at each clip. You cannot go back and review or change your responses after the clip has played.
How does the hazard perception test scoring work?
You can score up to 5 points for each developing hazard.
The earlier you spot the hazard as it starts to develop, the higher your score can be.
You do not lose points just because you click at the wrong time. However, you will not score anything if you click continuously or in a pattern.
The pass mark for the car hazard perception part is 44 out of 75.
What happens before the hazard perception test starts?
Before the hazard perception test begins, you will be shown an explanation video about how it works. This helps you understand what to look for before the scored clips begin.
Use the introduction carefully. It is not just a formality; it is your reminder of how to respond during the clips.
Hazard perception test practice
Hazard perception test practice can help you understand what developing hazards look like and when to respond. The aim is not to click constantly. The aim is to recognise the moment a hazard starts to develop.
Good practice should help you:
- understand what a developing hazard is
- avoid clicking too early or too late
- spot road users who may change what you need to do
- build confidence with the video format
- avoid patterned or repeated clicking
- learn from clips after you complete them
Start hazard perception test practice
Free hazard perception test clips
Free hazard perception clips can be useful when you are learning how the format works. They can help you understand what to expect before moving into deeper preparation.
However, free clips should only be one part of your preparation. You still need to revise theory questions, take mock tests and build a good understanding of road rules.

Common hazard perception mistakes
Learners often lose marks because they misunderstand what the test is looking for.
- Clicking when a hazard is only potential, not developing
- Clicking too late after the hazard is already obvious
- Clicking continuously or in a pattern
- Forgetting that one clip has two developing hazards
- Only practising multiple-choice questions and ignoring hazard perception
- Expecting the clip to be replayed
How to improve your hazard perception score
Improving your hazard perception score usually means practising the skill of noticing change. Ask yourself what could affect your speed, direction or position.
- Look well ahead in the road scene.
- Watch pedestrians, cyclists and parked vehicles carefully.
- Notice brake lights, indicators and changes in road position.
- Click when the hazard starts to develop, not when it is already over.
- Review practice clips afterwards where possible.
- Practise regularly rather than only the night before your test.
