Use GOV.UK to book your test: using an unofficial site could cost you more or not actually book a test at all
Booking and taking the LGV instructor theory test
When you’re ready to take your large goods vehicle (LGV) instructor theory test, book your test at a local test centre using the guide below. Remember, you must pass your theory test before you can take your practical test.
If you’ve already used an unofficial booking website, you might have seven working days to cancel your order and get all your money back but this will depend on the terms and conditions of the website you used.
The qualifying process for becoming an LGV instructor is similar to the process for becoming an approved driving instructor. Watch DVSA’s video about the driving instructor theory test for a guide to what will happen at your test.
