The theory test is a two part test, which you need to pass before you can book the practical driving test. You need to go to a test centre to do this – in Bristol, this is located at Third Floor North Building, Crescent House, Temple Back, Bristol, BS1 6EZ.
The first part of the theory is a computerised multiple-choice test of 50 questions and you need to pass at least 43 of the questions correctly. The second part is the hazard perception test which consists of fifteen video clips. You will need to identify the hazards in the clips and the sooner you notice the hazard the higher mark You will need to score a minimum of 44 out of 75 to pass the test.
You must pass both parts of the test at the same time. The test certificate is valid for 2 years. You are allowed to take practical driving lessons before taking the theory test.
I always recommend trying to take two hour lessons. During a two hour session you are able to learn much more, as well as having more time to practice exercises. If you can't do two hour lessons then its not the end of the world.
I also run intensive courses and refresher sessions. Refreshers are perfect for people who have lost their nerve, not driven for a long time, or maybe just haven't driven in the UK before.
