ADI Part one is a theory test of your driving knowledge. Many people overlook this part of becoming a driving instructor. It if you rush through this test you will already be building very poor foundations for the rest of your career.

This exam is easy compared to the others but that doesn’t mean you should underestimate it. The knowledge you gain in part 1 will be what you rely on in later exams and your whole career.

Rush through part 1 at your peril. Not knowing the rules and regulations of driving will come back to bite you later.

Part 1 is easier than the other exams because you have an unlimited number of attempts at it.



How the test works

You have to answer 100 questions about driving and then complete a hazard perception test. If you pass both of those you will have passed part one.

The questions are in 4 bands –

1) Road procedure

2) Traffic signs and signals, car control, pedestrians, mechanical knowledge

3) Driving tests, disabilities, law

4) Publications, instructional techniques


There are over 900 different questions.

You must score 85% (so 85 questions must be answered correctly) but you must also get 80% in at least each band to ensure your knowledge is broad enough. For example, you can get 100% in bands 1, 2 and 3 and 75% in band 4 and you’ll fail because you didn’t reach the minimum 80% level in band 4.

You have 90 minutes to complete this test so don’t rush it!


Hazard perception test


You’ll watch 14 video clips. There are 13 clips that contain one hazard and one clip that contains two hazards. For each hazard you’ll be given a score out of 5. The earlier you see the hazard the more you score.

You must get 57 out of 75 to pass this test. DVD’s are easily available through amazon, ebay etc. to help you practice this and they will explain it in much more detail than i can here.



Part 1 training books

It contains “Essential skills” which is the book all driving instructors use as a reference. It also contains DVD’s that you’ll be recommending to learners and you can practice the theory test that they take. You’ll need to know all about the driving test and theory test because pupils will be asking you lots of questions about them.

You’ll be sent a copy of all the questions and answers when you apply to start the ADI qualifying process (you can start that by clicking on the link above). It costs £6 and that can be enough to scrape though by learning all the questions and answers but that is not a good way of doing it. It’s not just about passing part 1, it’s about building your knowledge for the rest of your career.
