The ADI Part One Test

The ADI Part One Test is the first of three qualifying tests that you will need to do to become a fully qualified DVSA ADI.

It’s not too different to the theory test that is taken by learner drivers. You may have already taken one of those tests and are familiar with how it works. If you are not, or even if you are, read on.

Multiple-choice questions

You have 1 hour and 30 minutes to answer 100 multiple-choice questions.

Before the test starts you’ll get:

How the test works

There are 25 questions in each of these 4 categories:

A question and several possible answers appear on a screen. You have to select the right answer.

Leaving a question

You can ‘flag’ questions that you want to come back to later.

Changing your answers

You can go back to any question to review and change your answer at any point.

When you’ve finished

You can finish the multiple-choice questions part when you’ve answered all of the questions. You do not have to use the full 1 hour and 30 minutes.

You can have a break of up to 3 minutes before the hazard perception test starts.

Hazard perception test

Before you start the hazard perception test, you’ll be shown a video about how it works.

You’ll then watch 14 video clips. The clips:

You get points for spotting the developing hazards as soon as they start to happen.

What is a ‘developing hazard’

A developing hazard is something that would cause you to take action, such as changing speed or direction.


A car is parked at the side of the road and is not doing anything. It would not cause you to take action, so it’s not a developing hazard.

When you get closer, the car’s right-hand indicator starts to flash and it starts to move away. You’d need to slow down, so it’s now a developing hazard.

How the scoring works

You can score up to 5 marks for each developing hazard.

To get a high score, click the mouse as soon as you see the hazard starting to develop.

You do not lose points if you click and get it wrong. However, you will not score anything if you click continuously or in a pattern.

You only get one attempt at each clip and unlike the questions, you cannot review or change your responses.

Pass mark and test result

You’ll get the result at the test centre after taking the test. You must pass both parts to pass the test.

To pass the multiple-choice part, you must get both:

You’ll fail if you get an overall score of 85 or higher, but do not score high enough in each of the 4 categories.

To pass the hazard perception part, you need to score at least 57 points out of 75.

If you pass

You’ll get a pass certificate letter if you pass the test. You’ll need this when you book and take your approved driving instructor (ADI) part 2 test.

Your pass certificate number lasts for 2 years. You must qualify as an ADI in that time, otherwise you’ll have to start the application process again.

If you fail

You’ll get a letter at the test centre. It’ll tell you which parts you did not score enough points on so you know what to practise.

You must book and take the full test again.

You have to wait at least 3 working days before taking your test again.

When you pass your Theory Test you can proceed to Part Two
