The UK car theory test explained

The car theory test is two tests in one appointment. You answer multiple-choice questions on a screen, take a short break if you want one, and then watch a set of video clips for the hazard perception part. Both happen on the same day, in the same room, and you have to pass both of them. Pass one and fail the other, and you resit the whole thing.

Below is what each part involves, what happens when you arrive, and what to do with your result. Everything here matches the DVSA's guidance on GOV.UK as of October 2026. Rules do change, so check gov.uk/theory-test before your test.

Who needs to take it

You need to pass the theory test before you can book your practical car test. To book it you need a provisional driving licence, and you can take the test from your 17th birthday. If you get, or have applied for, the higher rate of the mobility part of Personal Independence Payment (PIP), you can take it from 16.

There are a few exceptions, such as upgrading an automatic car licence to a manual one. If you already hold a moped or motorcycle licence, you still need to pass the car theory test before the car driving test.

Booking the test

Book on GOV.UK. The car test costs £23, and you need your provisional licence number, an email address and a debit or credit card. For a test in England, Scotland or Wales you must have lived in Great Britain for at least 185 days in the 12 months before the test date.

Some websites offer to book the test for you and charge more for it. You don't need them: the official service is cheap and straightforward. If you have a reading difficulty, a disability or a health condition, say so when you book, because the support available has to be arranged in advance. We cover that in our guide to theory test support.

In Northern Ireland the theory test is booked and run separately, through nidirect, so check their pages for the booking details.

Part 1: the multiple-choice questions

You get 50 questions and 57 minutes. Before the real questions start you'll see some instructions and a practice question, so you can get used to the screen before the clock matters.

Three of the 50 questions are about a short video with no sound, showing an everyday drive such as a trip through a town centre. You can play it as many times as you need.

You can flag a question and come back to it, and you can change any answer before you finish. Most people have plenty of time, so there is no need to rush the first pass. A sensible approach is to answer everything you're sure of, flag the rest, then use the remaining time on the flagged ones.

The pass mark is 43 out of 50, which means you can drop 7 marks. That sounds generous until you remember the questions cover everything from tyre tread depths to what a particular road marking means. Our advice is to wait until you're scoring 45 or more on mock tests fairly consistently, so a few unlucky questions on the day don't decide your result.

The break

After the multiple-choice part you can take a break of up to 3 minutes before the hazard perception part starts. Take it if you can. A short pause makes it easier to switch to a completely different kind of test.

Part 2: hazard perception

You watch 14 clips of everyday road scenes. Each has at least one developing hazard, meaning something that would make you change speed or direction, and one clip has two. You click when you see a hazard starting to develop, and the earlier you click within the scoring window, the more points you get, up to 5 per hazard.

That gives 75 points in total, and the pass mark is 44. You only get one go at each clip, and you can't go back and change your responses. Clicking constantly or in a pattern scores zero for that clip.

The scoring is the part most people misunderstand, so it has its own guide: how hazard perception scoring works.

On the day

Take your UK photocard driving licence. If you still have an old paper licence, you also need a valid passport. With a Northern Ireland licence, take both the photocard and the paper counterpart. If you've changed your name, bring proof such as a marriage certificate or deed poll. Without the right documents the test is cancelled and you don't get your money back.

Aim to arrive 15 minutes early. If you're late, the test is cancelled and you lose the fee.

At the centre you'll put almost everything in a locker: bags, coats, hats, your phone, watch, wallet, earphones and whatever is in your pockets. All electronic devices, including smartwatches and fitness trackers, have to be switched off before you go in. Staff will check your ID against your face and carry out some simple security checks, such as asking you to empty your pockets and show your ears. There's no waiting area for anyone who comes with you, so let them know they'll need to wait elsewhere.

Your result

If you pass, you get a pass certificate number. Keep it safe: you need it to book your practical test, and it lasts for 2 years. If you haven't passed the practical test within that time, you have to take the theory test again.

If you fail, you'll get a letter showing which parts you didn't score enough on. You can book again for a date at least 3 working days away, and you have to take both parts again, even if you passed one of them.

You wouldn't be alone: fewer than half of car theory tests end in a pass. Our theory test pass rates page has DVSA's official figures, including the pass rate at every test centre.

How to prepare

The questions come from a large bank covering 14 topics, so the best preparation is steady practice across all of them rather than cramming one area. Our three-week revision plan sets out a realistic schedule. Practise hazard perception separately too, because it tests a different skill.

If you'd like to practise on your phone, our app covers all 14 topics, mock tests with the same format and pass mark, and hazard perception practice. The DVSA also publishes official revision material on GOV.UK, and it works well alongside any app.
