ADI Part 1: Theory and Hazard Perception

Your first Driving Instructor Test is a theory exam consisting of 100 multiple choice questions. If you have any questions or queries regarding Part 1 of your training your Personal Trainer is always there to help.

The test takes around 1 hour 45 minutes and includes:

  • Multiple Choice Questions
  • Hazard Perception

You’ll be asked 100 questions in total. There are 25 questions in each of these 4 categories:

  • Road procedure
  • Traffic signs and signals, car control, pedestrians and mechanical knowledge
  • Driving test, disabilities, and the law
  • Publications and instructional techniques

The question and several possible answers will appear on a computer screen. Some will need more than one answer.

You can move between questions and ‘flag’ questions that you want to come back to later.

You’re allowed up to 90 minutes for the multiple-choice part.

To pass the multiple-choice part you must get both:

  • An overall score of at least 85 out of 100
  • At least 20 out of 25 in each of the 4 categories

You’ll fail if you get an overall score of 85 or higher, but don’t score high enough in each of the 4 categories.

You’ll be shown a video clip about how the hazard perception part works.

You’ll then be shown 14 clips that feature everyday road scenes. There’ll be:

  • 1 developing hazard in 13 of the clips
  • 2 developing hazards in 1 of the clips

A developing hazard is something that may cause you to take some action, such as changing speed or direction.

You can get up to 5 points for each hazard. You need to score at least 57 points out of 75 to pass this part.

The earlier you notice a developing hazard and make a response, the higher you score.


When you first see a parked car, it isn’t doing anything. When you get closer to it, you notice that its right-hand indicator starts to flash. The hazard is now developing and a response at this point would score marks.

You won’t score anything for a clip if you click continuously or in a pattern.
