We are happy to be able to offer ADI Part 1 driving instructor training at ADIT. At our office trainees can learn how to go through the theory questions and the hazard perception section - with 1-2-1 training. The good news is that potential driving instructors (PDIs) are able to study Part 1 around their own commitments. ADI Part 1 bookings and enquiries.

About ADI Part 1

ADI Part 1 Theory Test

There is no limit to the amount of times that the ADI part 1 test can be attempted.

It is a computer based test in which candidates have to answer multiple choice questions and respond to video clips of various driving situations.

The Part 1 test takes approximately 1 hour 45 minutes to complete and consists of 2 sections:

  • multiple-choice questions
  • hazard perception video clips

Both sections of the test must be passed at the same sitting in order for the potential driving instructor to receive an ADI Part 1 pass.

To help those that are not confident at using computers, it's possible to try a short practice session on the test computer before starting the actual test. Staff at the test centres will also be able to help with any concerns or questions before the test begins.

ADI Part 1 Theory Test

The theory test is the first part of ADI Part 1; candidates have 90 minutes to answer 100 multiple choice questions.

The questions on the computer screen are clear and it's easy to navigate through them or to come back to something later. It's also possible to go back and change answers within the 90 minutes allowed.

Part 1 is designed to test a potential driving instructor (PDI) on their knowledge of:

  • the Highway Code
  • rules of the road
  • instructional techniques

The required knowledge has been split into 4 groups to ensure that potential driving instructors are tested on all areas required for teaching pupils. The 4 groups are:

  • road procedure
  • traffic signs and signals, car control, pedestrians, mechanical knowledge
  • driving test, disabilities, law
  • publications, instructional techniques

ADI Part 1 Hazard Perception Test

After a short break, the second part of the test will begin, this is the hazard perception section which consists of 14 video clips, each around 1 minute long.

Before the actual hazard perception test videos start, there is a tutorial which explains how the test works and what to do.

The ADI Part 1 video clips contain footage filmed from a driver's point of view; each clip shows a different scenario. The candidate, playing the role of the driver, has to decide when a hazard situation is starting to develop in front of the vehicle, and whether they would have to take an action such as changing direction or speed, as a result.

Marks are awarded when candidates spot a developing hazard and press the mouse button. More marks are awarded if the hazard is spotted early, and less as the hazard develops.

In the 14 video clips there are 15 hazards where it's possible to score marks; the maximum score for each hazard is 5 points.

The Marking System

The overall score required to pass ADI Part 1 is 85%. The minimum pass marks for each section are as follows:

  • multiple-choice - 80% (at least 20 correct questions from each of the 4 groups)
  • hazard perception - 57 out of a possible 75

Candidates should receive the results of ADI Part 1 before leaving the test centre. They will also be notified of the scores they received for each Theory Test group.
