ADI Part 1

In order to become either a PDI (potential driving instructor) or ADI (approved driving instructor), you must complete three tests, the first of these being the ADI Part 1.

The Part 1 ADI theory test comprises of two sections; multiple choice and the hazard perception test. Both sections of the theory test must be passed in order to pass. The ADI theory test closely resembles the learner driver theory test. The ADI theory test comprises of 100 questions compared to 50 on the learner version. Many of the questions are similar although some of the questions will be related to driving instruction.

ADI Part 1 Multiple choice

Provided will be 90 minutes to answer 100 questions. Four possible answers will be available for each question. You can select your answer by touching the computer screen or by using the mouse. On certain questions, there may be more than one answer required. If so, this will advise you on screen. 85% will need to be scored in order to pass the theory part of the test. Additional time or a voice-over can be granted to individuals who have reading difficulties. The multiple choice section is banded into four main areas:

  • Road procedure
  • Traffic signs, traffic signals, car control, pedestrians, mechanical knowledge
  • Driving Test, disabilities, law
  • Publications, instructional techniques

Although the overall pass is 85%, you must reach a minimum mark of 80% in each of the 4 subject areas. 20 out of 25 questions in each band must be passed. For example a score of 25, 25, 25 and 19 would be 94% but would not be acceptable and would result in a fail.

ADI Part 1 Hazard perception

ADI Part 1 hazard perception

The hazard perception part of the theory test is viewed on a computer screen consisting of 14 video clips which feature every day road scenes. Every video clip will feature at least one developing hazard, although one of the clips will feature two developing hazards. When you spot a developing hazard click the mouse button.

A tutorial will be given before the hazard perception test starts. For each hazard a maximum score of 5 can be reached. If you spot the hazard in good time and click the mouse a score of 5 can be rewarded. This score descends from 5 to 0 depending on the time it takes you to spot the hazard.

The sooner you spot the hazard the better your score will be. The pass mark for the hazard perception part of the theory test is 57 out of 75. At the end of the test you will receive printed paper containing your results.

ADI Part 1 training

There driving instructor training establishments that will train you for all 3 exams. To keep the training costs to a minimum however, you may benefit from studying the Part 1 ADI exam using your own sourced materials and to study in your own time. Training materials required:
