About the ADI Theory Test
The ADI theory test requires a higher degree of knowledge than the normal driving theory test for learner drivers. The test, which is conducted on a computer, is carried out in two parts: a multiple choice part and a hazard perception part. Both parts are taken at the same sitting. The test is available in English and Welsh.
Multiple choice questions
- The Highway Code
- the rules of the road
- instructional techniques.
Prior to the test itself, you’re allowed a 15-minute practice session allowing you to get accustomed to the interface before starting. Staff at the test centre will be on hand to help with any difficulties you may have.
The screens are clear and easy to read. A single question will appear on your screen at a time; you can use the arrows to move backwards or forwards through the questions if need be. You can also go back to any questions that you want to look at again. Changing your answers is straightforward.
You’ll have 90 minutes to answer 100 questions, which are split into four bands of 25 questions each.
The four bands cover the whole syllabus to make sure that candidates have a complete understanding of the theory. They are
- road procedure
- traffic signs and signals, car control, pedestrians, mechanical knowledge
- driving test, disabilities, law
- publications, instructional techniques.
The questions are multiple choice and you’ll be asked to select the correct option for each. You do this by clicking a mouse.
ADI Hazard perception test
The hazard perception test explained
Each clip contains one or more developing hazards, such as vehicles, pedestrians and road conditions. You’re required to respond to each situation by clicking the mouse as soon as you become aware of a developing hazard that may cause you, the driver, to take action, for example changing speed or direction.
The earlier you spot and respond to a developing hazard, the higher you score. However, you must wait until the hazard actually starts to develop and not click too early.
Your response won’t cause the scene in the video to change in any way, although a red flag will appear towards the bottom of the screen showing that your response has been registered.
Before each clip starts, there’ll be a 10-second pause so that you can see the new road situation.
The hazard perception test lasts about 20 minutes.
There are 15 scorable hazards in total. You can score between one and five marks for each chip, five being the highest. The total available score is 75.
Why is the hazard perception test included in the ADI theory test?
Just as in the theory test for learner drivers and riders, the hazard perception test is included in the ADI part 1 theory test to assess your skills in
- hazard recognition.
How does it differ from the hazard perception test that learner drivers and riders take?
Although all car and motorcycle candidates are shown 14 clips, the ADI hazard perception test is different because the pass mark is higher. To pass
- learner drivers and riders must achieve a score of 44 out of 75
- potential driving instructors must achieve 57 out of 75.
This is because ADIs are expected to have a higher standard of knowledge and better reactions than a learner, so you’ll need to prepare thoroughly.
ADI Theory Test pass mark
So, it’s possible for you to get an overall mark of 85% or higher but still fail the test because you haven’t gained the minimum of 80% in one or more of the four bands.
For the ADI hazard perception test, you need to score at least 57 out of 75.
The results of your theory test are usually given to you before you leave the test centre, along with details on applying for the test of driving ability if you’re successful. If you fail, you’ll be told which bands contained wrong answers. You won’t, however, be given details of the actual questions.
How to book the ADI Theory Test
You will need your driving licence number and personal reference number to hand when making your application.
Booking arrangement details will be sent to you once you have received approval to start the qualifying process.
ADI theory test appointments can only be made once your application form has been submitted, processed and an acceptance letter issued.
Number of attempts
How to prepare for the ADI Theory Test
- being able to use speed correctly
- maintaining a safe distance between your vehicle and other road users
- scanning the road effectively
- anticipating and planning for potential hazards.
You can learn all of these skills and we recommend that you prepare with a professional instructor as part of a structured programme.
Provision for special needs
If you do have these needs, DVSA will need to see a letter about your reading ability from any of these people
It may not be possible for you to get a relevant professional person to write this letter; if this is the case, DVSA will consider a letter from an independent person who knows about your reading ability, such as an employer.
