The practical test is about 40 minutes long, allowing you to demonstrate everything you've learned in your driving lessons. Before you start the practical test the examiner will ask you to read the number plate of a parked vehicle to check your eyesight. You'll then be asked two vehicle safety check questions known as the "show me, tell me" section. You'll be asked to do two of the three reversing manoeuvres you've practiced with your instructor, and possibly make an emergency stop. Also a 10 minute independent driving section you'll be expected to show that you can make safe decisions.
Currently a weekday practical test costs £62. Evening, weekend and bank holiday tests cost £75, plus the cost of booking the instructor and car for the duration of the test. You can book your practical test online here.
