ADI Part 1
The part 1 ADI theory test is split into two parts, the multiple choice part
and the hazard perception part. The multiple choice part is conducted on a touch
screen computer and the hazard perception part records your responses through a
Both parts of the test must be successfully passed at the same time or the test will need to be retaken.
Before the test begins you will be given instruction on how the test works.
If required, you can choose to go through a practise session of multiple choice questions to get used to how the test works on screen. At the end of this session the real test begins.
A question and four possible answers will be shown on screen and you must select the correct answer by touching the screen or by pressing the mouse. Occasionally some questions require more than one answer. If you encounter a ‘tricky’ question, it can be ‘flagged’ and returned to later in the test. You will have 90 minutes to answer 100 questions which are split into four bands covering:
Traffic signs and signals, car control, pedestrians, mechanical knowledge
Driving test, disabilities, law
Publications, instructional techniques
The questions are ‘banded’ to ensure a comprehensive knowledge across the whole syllabus. The pass mark is 85%, that is 85 questions passed correctly overall. However an n 80% pass mark in each of the four bands is also required. Therefore it is possible to score 94% overall and yet still fail the test as one band is below the required score.
Following the multiple choice, a short break is available before the hazard perception begins.
A short tutorial video clip will be shown initially about how this part of the test works.
The hazard perception test is delivered on computer requiring a response by pressing a computer mouse button. A series of 14 video clips, each lasting about one minute is shown. In each one, familiar, every day road scenes, each with a developing hazard will be shown. One of the clips will contain two developing hazards. To achieve a high score, you will need to respond to the developing hazard at the earliest point of its development. On each clip, the maximum score possible is 5 marks. There will be no opportunity to review your responses, as; on the road you only have one chance to make the correct decision. The pass mark at present is set at 57 marks out of a possible 75.
There are facilities for those candidates with special needs. These should be requested at the time of booking.
