The DVSA Hazard Perception Test: What you Need to Know

The DVSA hazard perception test is part of the theory test. During this part of the theory test, you will view 14 video clips. Each of these clips lasts for approximately 1 minute each. There is a total of 15 hazards to find, meaning there is at least one hazard in each clip.


Taking the Official DVSA Hazard Perception Test

During the test, you will be expected to click a mouse button when you spot a hazard. The speed of your click will help to determine your overall score for that clip. You can score between 0 points and 5 points for each hazard. The maximum score is 75, and you need to score at least 44 points to pass this part of the theory test.

The Process

The official dvsa hazard perception test will begin with a short tutorial. This tutorial will be played on a computer screen and it will show you how the test works. It will also explain what you need to do during each of the clips. At the end of the tutorial, you will have an option to take the test or to play the tutorial again.

The Hazard Clips

Each hazard clip will show a freeze-frame at the beginning of the video. You will also notice a countdown from 10. When the countdown comes to an end, the clip will begin to play. When you see a hazard developing, you will need to click the mouse.

The programme will let you know when your click has been registered. A red flag will appear across the bottom of the screen. You will see one red flag for each click you make in the clip you’re viewing. Once the clip has ended, all of the red flags will disappear. You will then start a new clip.

Each clip will contain a few potential hazards. However, the only real hazard that involves other users of the road will be marked. A hazard such as this is known as a “Developing hazard”. This means you will only be awarded a point if you spot the hazard before another road user takes evasive action. For example, if a van is pulling out and results in another driver having to swerve or slow down.


How to Score Points

Your score will depend on how quickly you spot a developing hazard. The hazard is recorded from the time when it could potentially be seen, to when the vehicle in question arrives at the particular hazard. This is the window or time frame that is used to help determine your score.

The window or time frame is divided into 5 different sections. If you spot the hazard early on and click the mouse during the first segment you will score 5 points (The maximum). If you click on the second segment, you will score 4 points, and so on. This part of the  official dvsa hazard perception test is accurate to 1/25th of a second.

Clicking more than once

If you choose to click more than once during a section, the computer will record your highest score. If you do not click the mouse in any section, you will not score anything for that particular hazard.

Clicking repeatedly

Unfortunately, people have tried to cheat on this test by repeatedly clicking the mouse. The computer can pick this up and it will set the score for the clip you’re watching to 0.


When you’re watching a clip, make sure you click the mouse whenever you see a hazard. The type of hazard you’re looking for is one that involves another road user. Consider anything that might cause a driver to change direction, position, or speed. Keep an eye on the hazard and click the mouse if it materialises. Doing this will make sure that you click within the scoring section.

Not all hazards will materialise. This means you won’t be scored for seeing them. It can be hard to work out when a potential hazard turns into a developing hazard. This is why it makes sense to click the mouse a few times. However, make sure you don’t click the mouse too early as you could miss the start of the section.


The Types of Hazards

There is a range of hazards to look out for while you take the dvsa hazard test:

  • Vehicles that emerge from driveways, parking places, or side roads
  • Areas where animals might walk into the road
  • Cyclists or pedestrians that are crossing the road
  • Meeting on-coming or slow-moving vehicles where the road is narrow or the vehicle makes the road narrow
  • Large vehicles that move or could move to your side of the road
