When the theory test has been passed and you are ready, the practical test can be booked here. The current cost to book a practical test is £62.
Your driving test will start with an eyesight check and some vehicle safety questions. You will then start your practical driving test which will include some specific manoeuvres.
The driving part of your test will last about 40 minutes. Throughout the test your examiner will be looking for an overall safe standard of driving, including when you are carrying out the set exercises. You can make up to 15 driving faults and still pass the test (16 or more results in failure). However, if you commit one serious or dangerous fault you will fail the test.
