The first test (ADI Part One) is a theory based test which contains a mixture of multiple choice questions based around the following:
- Road procedure
- Traffic signs and signals, car control, pedestrians and mechanical knowledge
- Driving test, disabilities and the law
- Publications and instructional techniques
Each category contains 25 questions, and in order to pass the multiple choice section you need an overall score of at least 85 out of 100, AND at least 20 out of 25 in each category.
If you get an overall score of 85% or more but don’t score enough in each of the 4 categories you will fail.
The hazard perception test will consist of 14 video clips which will feature road scenes you’ll see on a daily basis. They’ll contain at least 1 developing hazard; however one of the clips will contain 2 developing hazards.
In order to pass the hazard perception your score needs to be at least 57 out of 75.
You must pass both the theory questions and hazard perception at the same time in order to progress to taking your ADI part 2 test.
You will have two years from the date you pass your ADI part 1 to then fully qualify and pass your ADI part 3.
