About the LGV or PCV Theory Test

LGV Vehicle Markings Code

Before you take the LGV or PCV Theory Test (Module 1a and 1b), it's worth knowing exactly what is expected from you.


The LGV or PCV Theory Test is made up of two parts:

  • Module 1a – a multiple choice section
  • Module 1b – a hazard perception section.

Both parts can be taken at different times, but you must pass BOTH modules within 24 months to acquire a pass.

Module 1a will cost £26 to sit, whereas Module 1b costs £11.

Module 1b – Hazard Perception

To begin, you will be shown a short video clip which shows how the Hazard Perception Test works. You will then go through 19 video clips which feature everyday road scenes. In each clip there will be at least one developing hazard, but one of the clips will feature two, so it’s important to click each and every time you believe there is a hazard. There is a window of opportunity where a hazard is present. If you click the mouse at the beginning of this window, i.e. when the hazard has first appeared, you will score the maximum amount of points. If you don’t click right away, you will score fewer points, and if you click too late in the scoring window you will score zero.

The maximum points you can score in each hazard is five. The pass mark for the hazard perception part of the theory test is 67 out of 100.

People often find this part of the test more difficult than the multiple choice because there are no right or wrong answers, it is simply a case of clicking as soon as you see the hazard. Make sure you have a thorough knowledge of what’s expected of you by using the hundreds of professionally filmed hazard perception clips within Driving Test Success Online.

At the end of the test

When you have finished the test you may leave the examination room. Once you have left the room, you can not re-enter. You will then be given your result letter by a member of the test centre staff. The result letter tells you if you have passed or failed, and it gives you feedback on your test.

If you pass

You will receive a “pass letter” detailing the results of your test. When you have passed both the Theory and Hazard Perception parts of the test, you will receive your Theory Test certificate which includes a reference number. You will need to quote this number when you book your Practical Test. Your Theory Test certificate is valid for two years from the date you passed the first part of the test – the multiple choice test. If you do not take your Practical Test within this two year period you will have to take another Theory and Hazard Perception Test. There are no exceptions to this rule.

If you fail

If you fail you should look at the feedback on the letter you have been given and find out why you failed. As the Hazard Perception Test is a matter of perception rather than a right or wrong answer, people often find this the most difficult part of the test. See How to prepare for your test for information on how you can get the best possible practice. If you want to book another Theory Test you can book it straight away, but you cannot take it for another three clear working days. So, if you failed your first test on a Monday afternoon, you will have to wait until Friday morning before you can try again.
