What does the ADI Part One theory test involve?

ADI part one consists of 100 multiple-choice questions and a hazard perception test, which you have 90 minutes to complete.

The multiple-choice section tests your knowledge of these four categories:

  • Road procedure.
  • Traffic signs and signals, car control, pedestrians and mechanical knowledge.
  • Driving test, disabilities and the law.
  • Publications and instructional techniques.

The hazard perception test includes 14 video clips, 13 of which have one hazard and one clip has two hazards. Similar to the learner driver version, you’re looking for ‘developing’ hazards, and you get more points the earlier you spot the danger (up to a maximum of five points per hazard). You get one attempt at each video clip.

How long is the part one exam?

You’ll have an hour and a half to complete the part one test (the hazard perception section normally takes around 20 minutes). You’ll also get an extra 15 minutes before the test starts so you can get used to the system.

What’s the pass rate for ADI part one?

You’ll get your test results at the centre after completing the test. To pass the multiple-choice part, you’ll need an overall score of 85 out of 100 and get at least 20 out of 25 for each section. So, if you got 18 out of 25 in one section but got more than 85/100 in total, you will have failed the test.

The hazard-perception test is out of 75 (up to five points per hazard). To pass, you’ll need at least 57 out of 75.

If you fail, the test centre will give you a letter explaining which categories you failed. You must wait at least three working days before retaking the test.
