You can take your driving theory test when you're 17 and hold a provisional driving licence. You can book online or you can call on 0300 200 1122.

The Theory test consists of two parts - multiple choice questions and hazard perception. Both tests will be taken on the same day at the same venue. You must pass both the multiple choice and hazard perception parts in one session for a successful theory test. You'll find out if you were successful shortly after completing both parts of the test. If you fail either part of the theory test, you must wait three clear working days before you can resit the entire test again.

The multiple choice test is taken first and consists of 50 questions. Before the test starts you'll be given instructions on how it works. You can choose to do a practice session of multiple-choice questions to get used to the layout of the test. At the end of the practice session the real test will begin. You can move between questions and 'flag' questions that you want to come back to later in the test. Simply use the touch screen computer to answer the questions, you have 57 minutes to complete the test and must answer 43 questions correctly to pass.

The hazard perception test is taken second and consists of 14 video clips each containing one or more developing hazards, there are 15 developing hazards in the whole test. You'll be shown a short video clip of how it works before you start the test. To achieve a high score you must watch each video and click the mouse as soon as you see a developing hazard, you can get a maximum of 5 points per hazard and your score is based upon how early you respond to each developing hazards. To pass, you need to score 44 out of a possible 75 points.

Imagine a parked car on the side of the road. At first glance, it’s just sitting there, not doing anything. If you were to react at this moment, you wouldn’t gain or lose any marks. As you get closer, you notice its right-hand indicator starts flashing, signalling that the driver may be about to move. At this stage, the hazard is developing, and responding now would earn marks. The flashing indicator is the key sign that the car has shifted from a potential hazard to a developing hazard. As you approach even closer, the car likely begins to pull away from the side of the road, requiring another response.

You must take your UK provisional driving licence to your test.
