How the real DVSA ADI Part 1 theory test works
At the test centre you complete two parts back to back: multiple choice, then hazard perception. For ADI Part 1 you answer 100 questions on a touchscreen with up to 115 minutes. You need 85 out of 100 on that section.
Hazard perception uses video clips. The pass mark for ADI Part 1 hazard perception is 57 out of 75. This ADI mock theory test covers only the multiple-choice part. Use our hazard perception practice for the second half.
Book only through gov.uk. Third-party booking sites sometimes add fees. Becoming an ADI also involves Part 2 driving and Part 3 instructional ability tests after Part 1.

Tips to pass ADI Part 1 first time
- Run a full timed ADI mock theory test at least once a week while you prepare for Part 1.
- Revise the Highway Code deeply; instructors are expected to explain rules clearly to pupils.
- Read every explanation after a mock, including answers you guessed correctly. Part 1 questions often test fine details.
- Practise hazard perception separately. Passing this mock does not mean you are ready for the clips.
- Break revision into short sessions. One hundred questions is a long sit; build stamina gradually.
What to revise if you fail this ADI mock
Check your results breakdown by topic. If signs or motorway rules dragged your score down, spend two short sessions on those areas, then retake the ADI mock theory test. If attitude, documents or teaching themes were weak, reread ADI qualification guidance on gov.uk.
Do not book Part 1 until you are beating 85 comfortably more than once. A single pass after lucky guesses is not enough.
What happens if you fail ADI Part 1
You can retake Part 1, but you must pass Part 1 and hazard perception within the allowed time window to continue qualification. Use failed attempts to target weak topics, then book through gov.uk when mock scores are stable.

ADI mock theory test FAQs
Is this ADI mock theory test free?
Yes. Tap start on this page. We do not ask for payment details or an account.
How many questions are in the ADI Part 1 mock?
This ADI mock theory test uses 100 multiple-choice questions, matching the Part 1 exam at a test centre. Hazard perception is a separate section on the real day.
What is the pass mark on an ADI mock theory test?
You need 85 correct answers out of 100 on the multiple-choice part. That is the same pass mark DVSA uses for ADI Part 1 in Great Britain.
How long do I get on the ADI mock?
Up to 115 minutes for all 100 questions. The timer matches the official ADI Part 1 multiple-choice time limit.
Is this the same as the learner car mock?
No. Approved driving instructor Part 1 uses a longer paper and a higher pass mark than the standard car learner test.
Are these the same questions as the DVSA ADI test?
No. Theory Mock uses original practice questions aligned to Highway Code topics and instructor themes. They are useful revision, not a copy of the live DVSA bank.
Can I pause the ADI mock theory test?
You can close the browser and return later. Progress is stored on this device. The countdown keeps running while you are away, like leaving the room mid-exam.
What score should I get before I book ADI Part 1?
Aim for 88 or more on repeated mocks, not a single pass at 85. Book through gov.uk when your results are steady.
