What happens on the day?

Before you start the multiple choice test, you can have a 15 minute practice session to get used to the format of the test.

Part 1a: Theory test multiple choice

You have 1 hour 55 minutes

  • Answer 100 multiple choice questions from 15 topics
  • Score at least 85 correct to pass
    • Use a mouse to choose the correct answers on screen
    • You can flag any questions you're not sure of and review later

Part 1b: Hazard perception

In this test you’ll be shown 19 video clips in which there are 20 developing hazards to spot overall.

  • You have the option of a 3 minute break before you begin
  • Put on the headphones and watch a short video, which shows you how the test works
  • Click the mouse whenever you see a developing hazard

A developing hazard is something that would need you, the driver, to take some action, such as changing speed or direction.

  • 19 clips (1 clip containing 2 developing hazards)
  • 5 points (max) per developing hazard response
  • 67 out of 100 to pass

: If you click the mouse too much or if you click in a pattern, you’ll be given a warning message and you’ll score no points for that clip.

Getting your results

You’ll be given your results shortly after you’ve finished the test.

If you pass

You’ll get a letter with your pass certificate number (use this to book your Driver CPC part 3a and 3b driving tests).

Your certificate is valid for 2 years. If you do not pass your Driver CPC part 3 test in that time you’ll have to retake your HGV theory test.

If you do not pass

You’ll need to wait at least 3 working days before you can retake it. Use this time to do some more preparation.
