ADI Part 1 theory test questions

The ADI Part 1 multiple-choice part has 100 questions split evenly across 4 categories. You need at least 20 out of 25 in each one, so it pays to know what they are.

The 4 categories

• These rules apply in Great Britain. The ADI part 1 test works differently in Northern Ireland. [1]
• You have 1 hour and 30 minutes to answer 100 multiple-choice questions, with 25 questions in each of 4 categories. [1]
• Road procedure. [1]
• Traffic signs and signals, car control, pedestrians and mechanical knowledge. [1]
• Driving test, disabilities, and the law. [1]
• Publications and instructional techniques. [1]
• The GOV.UK guidance names the categories but does not say which topics or publications fall under each one. [1]

How the questions work

• A question and several possible answers appear on a screen, and you select the right answer. [1]
• You can flag questions to come back to later, and go back to any question to review and change your answer at any point. [1]
• If you said you have a reading difficulty when booking, you can ask for an English voiceover and hear the questions and possible answers as many times as you like. [1]

What the questions are based on

• The questions are based on a list of publications: The Highway Code; Know your traffic signs; Driving - the essential skills; The Official DVSA Guide to Learning To Drive; the Driving Instructor's Handbook; Practical Teaching Skills for Driving Instructors; National standard for driving cars and light vans; National standard for driver and rider training; Driving instructor code of practice; and Carrying out driving tests: examiner guidance, not including sections 2, 3, 4, 5 or 15. [1]

The score you need

• To pass the multiple-choice part you need at least 85 out of 100 overall and at least 20 out of 25 in each of the 4 categories. You fail if you score 85 or higher overall but fall short in any category. [1]
