ADI Part One

Theory and hazard perception

To be a safe driver and an effective instructor, you need a thorough understanding of the principles, rules and regulations included in all of the reading material recommended by the Driver and Vehicle Standards Agency (DVSA).

As a professional driver trainer, you should be able to:


  • apply these principles, rules and regulations whenever you are driving;
  • pass on all of this information to your pupils to help them acquire the skills needed to put them into practice effectively;
  • give accurate answers to any questions your pupils may ask.

Theory test

This is a 2 part test consisting of a multiple choice questions and hazard perception videos.


Multiple Choice


You have 90 minutes to complete 100 multiple choice questions. These questions are banded into four subject groups:

  1. road procedure
  2. traffic signs and signals; car control; pedestrians; mechanical knowledge.
  3. driving test; disabilities; law.
  4. publications; instructional techniques.


Multiple Choice pass mark


The overall pass mark is 85%. However, the DVSA needs to ensure that you have an adequate knowledge in all of the subject areas and you need a score of 80% in each band to pass. This means that, even if you score 99% in 3 of the bands and 79% in the fourth, you will fail. This should emphasize to you the need for a thorough understanding of the principles covered in all of the recommended materials.

Following completion of the theory test, you will be given a short break before taking the hazard perception test.


Hazard perception test


Before you start this, as with the theory element, you will be allowed a short practice session.

The test consists of 14 video clips. You must watch carefully and respond to the hazards by clicking on the mouse. As each hazard develops, you need to keep registering a response to the changing situation - just as you would be assessing and reassessing developing situations when driving.

Each hazard is allotted a maximum score of 5 points, and the earlier you spot the hazard, the more points you will achieve. Provided your responses are made to correspond with the potential hazards or changing situations, you should be able to achieve a maximum score.

A skilled driver could be expected to click, on average, 10 to 12 times in one clip. However, you have to be careful not to click too early, or at random, as this will result in a negitive score.


Hazard perception test pass mark


To pass you must score 57 out of a possible 75 marks. If you fail this part of the test you will have to take both parts again.


Should you fail the theory 3 times, you would have to wait 2 years and restart the process again.


Resource materials

As you can see from the resource material needed, it is quite involved. Many who pass the ADI part 1, then go onto struggle with part 2 and certainly part 3, simply because they've cut corners on the theory side. Either by learning the questions via rote or by accepting a correct guessed answer.
