363 original multiple-choice practice questions in the four categories of the ADI Part 1 theory test (Great Britain), each with the answer, an explanation and the source it relies on. Hazard perception is not covered.
This pack is for anyone preparing for the multiple-choice part of the ADI Part 1 theory test, the first of the three tests to become an approved driving instructor for cars in Great Britain. It has 363 original multiple-choice questions in the four categories GOV.UK names: road procedure; traffic signs and signals, car control, pedestrians and mechanical knowledge; driving test, disabilities and the law; and publications and instructional techniques. They are written by Plainfiles only from free public sources: the Highway Code and Know your traffic signs, legislation.gov.uk and DVSA guidance on GOV.UK.
Hazard perception is not covered. The real test has a second part, 14 video clips with a pass mark of 57 out of 75, and you must pass both parts. This pack has no video and cannot practise it, so passing its mock is not the same as passing the test. The publications and instructional techniques category relies on free sources only. We did not use the paid books on GOV.UK’s revision list, so its questions on teaching practice rest on the free national standard for driver and rider training and DVSA guidance, and may not cover everything the real test asks. The real multiple-choice part is 100 questions in 1 hour 30 minutes, 25 in each category, and needs at least 85 out of 100 overall and at least 20 out of 25 in each category; the self-marking mock follows that rule. Twelve questions follow the current voluntary ADI code of practice and say so; DVSA has said a new mandatory code is expected from late 2026 to early 2027, so check GOV.UK before relying on them.
Formats: Two A4 PDFs (question bank, and answers and notes) and one self-marking HTML file that opens in any modern web browser and works offline.

What is included
- Question bank (PDF, 47 pages)All 363 questions grouped by the four categories, with a summary of the test and an answer sheet to print.

What it is not
- These are original practice questions, not the real test. DVSA has not endorsed or checked them, they are not DVSA material, and they contain no questions from any real test, past paper, book or app. Passing these questions does not guarantee a pass.
- It does not cover hazard perception, the video part of the ADI Part 1 test. You must practise that part some other way.
- Its publications and instructional techniques category is written only from free sources, so it may not cover everything the real test asks.
- It is not legal advice. The law changes, so check the sources before you rely on an answer.
- It does not book your test. You book the ADI Part 1 test yourself on GOV.UK.
