The show me, tell me part of the practical driving test is 22 safety questions about the car. These safety questions are based on; fluids, tyres, lights, brakes, windscreens, steering and other safety aspects.
Your driving instructor should go through the show me, tell me questions and answers with you at the roadside and whilst driving.
At the beginning of your practical driving test the driving test examiner will ask you one 'tell me' question. During your practical driving test whilst driving, the driving test examiner will ask you when safe, to 'show me' how you would do something i.e. set the demister controls.
You will not fail your practical driving test for getting the 'tell me' question wrong.
If you are unable to locate the requested control on the 'show me' part of the practical driving test, the driving test examiner will ask you to pull up on the left when safe. Once you have pulled up safely, the driving test examiner will help you to locate the requested control, confirm you know where it is, and then request that you drive on when ready. The 'show me' question will be asked again whilst driving!
You will only get one minor driving fault on your DL25 practical driving test report form even you get them both wrong, as long as you remain safe.
If whilst operating a control during the 'show me' question it becomes unsafe or dangerous i.e. you take your eyes of the road to look down at the demister control and the car veers to the left towards parked vehicles or right towards oncoming traffic, you'll be given a dangerous fault which will result in you failing your practical drivng test.
It's marked under 7. Vehicle Checks on the DL25 driving test report.
NOTE: Due to the fact that you can fail your practical driving test on the 'show me' part. It is vitally important that you not only take the time to learn the questions and answers, but familiarize yourself with all the controls, especially the ones relating to the 'show me' part, not just at the roadside, but whilst driving too!
