Hazard Perception

In order to book a driving test, learner drivers must first pass their driving theory test. The driving theory test is designed to test your knowledge of the Highway Code, as well as your ability to spot hazards while driving. The test consists of 50 multiple choice questions and 14 hazard perception clips.

What is the Hazard Perception?

There are 14 clips in the hazard perception test and each clip has at least one hazard, while one clip has two hazards. There are 5 marks available for clips with one hazard and 10 marks available for the clip with 2 hazards. You score points based on how early you spot a developing hazard, however you only score points once the hazard actually begins to develop. There are 75 marks available in total and to pass the test, you must score at least 44/75.

Why is the Hazard Perception Test Important?Preparing for this test is an important part of learning to drive. It is important you learn how to spot and deal with hazards in good time, as this will keep you safe while behind the wheel. Each driving course we offer has a number of driving lessons dedicated to planning, identifying and reacting to hazards.

Chapters in the Hazard Perception GuideThere are 7 chapters in the official DVSA hazard perception guide and these chapters are designed to teach you how to identify, react to and plan for developing hazards. The chapters in the guide are as follows;

Defining Hazards

A hazard can be defined as anything which causes you to alter your speed or change direction. Some hazards are fixed such as a roundabout or pedestrian crossing, while others could be temporary, such as a bus at a bus stop. Identifying what is and is not a hazard, is the first step in the process.

Looking For Clues

It is impossible to predict exactly what will happen at any given time on the road, however there are several clues and warning signs that we can use to prepare ourselves for a developing hazard. In this chapter, you will be taught how to identify clues that you could be approaching a hazard.

Using the MSM Routine

Identifying and spotting a hazard is the first step in the process, however you still need to respond and react to the hazard too. This chapter teaches you how to react to hazards using the Mirror Signal Manoeuvre (MSM) routine, which is one of the core driving principles you are taught when you learn to drive with Book Learn Pass.

Scanning and Planning

The key to efficient hazard perception, lies in your ability to spot and react to the hazard in good time. This chapter teaches you how to scan the road as you drive and plan accordingly, therefore reducing the chances of you being caught out by a hazard.


On busy urban roads, hazards do not appear one after the other, you are often in situations where you are faced with several different hazards at once. In such circumstances, you are required to prioritise which hazards you deal with first and this chapter teaches you the correct way to do so.

Cutting Down Risks

The number one objective of hazard perception is to keep you safe on the road and reduce the chances of you being involved in a collision with another road user. This chapter focuses on ways in which you can cut down on risks, such as keeping a safe distance from the vehicle in front, what to do when another vehicle enters your safety gap and how to drive in adverse weather.


This chapter deals with responding to the different type of hazards you can expect to face while driving. Once you have worked through the previous chapters, you should be able to identify and respond to hazards in good time and this chapter will test you ability to do so.

Hazard Perception Tips

The hazard perception test can be quite challenging, especially if it is your first time taking the test. To give you the best chance of passing, we have included our top hazard perception tips.

Learn How To Spot a Hazard

The first step to passing this test, is to learn how to identify a hazard. As a general rule, a hazard is anything that causes you to slow down, change direction or take evasive action. Thinking about whether a situation has the potential to alter your path, is key when analysing each individual clip.

Avoid Clicking Too Soon

You score points for identifying a developing hazard, however if you click too early, you will not score any points for the clip, as you are only awarded points for clicks which happen in a set period of time.

Potential vs Developing HazardYou only score points for identifying developing hazards, however all clips have potential hazards which you do not score points for. A pedestrian who does not cross the road for example, is a potential hazard and if you highlight this in the clip, you will not score any points for doing so.
