The practical driving test is a straightforward assessment of whether you can drive safely and independently. Understanding exactly what happens from arrival to finish removes uncertainty and lets you concentrate on performing well.
Before you leave home, make sure you have your provisional driving licence and your theory test pass certificate. Wear comfortable clothing and flat-soled shoes. Have a light meal and a good night's sleep. Arrive at the test centre about ten minutes early: rushing increases anxiety.
The test lasts approximately 40 minutes and includes: an eyesight check where you read a number plate from 20 metres; two 'show me, tell me' vehicle safety questions; general driving on a mix of road types; one reversing manoeuvre; and about 20 minutes of independent driving following a sat-nav or road signs.
The examiner is not trying to catch you out. They want to pass you. If you make a small error, stay calm: one minor fault will not fail you. Keep driving normally and do not dwell on mistakes.
If you do not pass, the examiner will explain your faults in detail. Use this feedback with your instructor to focus your practice before rebooking. The majority of learners who fail pass on their next attempt.
