There are 2 parts to the driving test for a large goods vehicle (LGV): a theory test and a practical test. You must pass the theory test before you can take the practical test.
The theory test has 2 parts: a multiple choice part and hazard perception test. You do not have to take both parts of the test on the same day but you must take them within 2 years of each other to get your theory test certificate.
The test is a really important part of learning to drive an LGV because when you get to your practical test you’ll need to show that you can use what you learn for this test when you’re driving on the road. It also forms Module 1 of your initial Driver Certificate of Professional Competence (Driver CPC) if you’re going to be driving for a living: see the Driver CPC page for more information.
It’s vital to prepare for your theory test; it may be a while since you last refreshed your knowledge of the rules of the road. The better prepared you are, the more likely you are to pass first time, which will save you the time and money that retaking the test will cost.
Preparing for the multiple choice test
The questions in the multiple choice test are taken from 3 books:
You’ll need to use all of these when you’re preparing. There are lots of products available that contain practice questions but it's really important you do not just learn the answers without understanding the questions fully because the questions on the actual test are not exactly the same as the practice ones.
Using official publications will help you get the most out of your preparation. You can find these and more on our online shop.
The multiple choice test covers the following topics
- vehicle weights and dimensions
- drivers’ hours and rest periods
- braking systems
- the driver
- the road
- incidents, accidents and emergencies
- vehicle condition
- leaving the vehicle
- vehicle loading
- restricted view
- essential documents
- environmental issues
- other road users
- road and traffic signs.
Tips to help you learn
There are lots of tricks you can use to help you learn what you’ll need to know for your test. Here are a few ideas.
- Link what you’re learning to your own experiences: for example, think about where you’ve seen an example of a road sign and use this to help you remember what the sign means.
- Use mnemonics: these are sayings or stories that help you remember something – for example, ‘Richard Of York Gave Battle In Vain’ reminds you of the colours of the rainbow (red, orange, yellow, green, blue, indigo, violet).
- Practise the question formats: as well as knowing all the information, you’ll also need to know how the questions are asked in the test. Use the practice test (see above) and the self-assessment questions in ‘The Official DVSA Theory Test for Drivers of Large Vehicles’.
- Plan your study: set yourself some timelines and targets. This will help you to see your progress and make sure you have not missed anything. Plan to do your studying somewhere you will not be disturbed and at a time when you’re fully awake.
- Get help: use friends, family, your driving instructor or your colleagues from work to ask questions and share driving experiences.
Preparing for the hazard perception test
This part of the test checks you can recognise and respond to hazards that could happen while you’re driving. Being out on the road with your instructor will help you prepare for this part. There’s also The Official DVSA Guide to Hazard Perception eLearning subscription.
In the test, you’ll see 19 film clips, each shown from a driver’s point of view. You’ll need to spot the developing hazard in each film: this is something that might need you, as the driver, to take some action such as changing speed or direction. For example, a car pulling in to the side of the road ahead of you is a developing hazard because you’ll need to slow down and manoeuvre around it.
