At the start of your driving test you’ll be asked 2 questions about vehicle safety checks. One will be to show them something and the other to tell them something. If you get either or both questions wrong you usually just get 1 minor fault but it is possible to fail the test on this section if you lose control of the car as you are performing the checks.
Do not turn the car on unless the examiner is sitting in the passenger seat. Turning the engine on while you are alone in the car counts as driving without a licence. Many cars now have a diagnostic system which shows you any problems with the vehicle on the dashboard.
You are not allowed to just say that the car would just tell you of any problems because the system may be faulty where as a manual check is more reliable. The only exception to this is the question about testing your ABS as it’s safer to see if the light is on than put yourself into a skid to find out! Below are the questions you could be asked and examples of how they could be responded to on your test day.
If the steering becomes heavy the system may not be working properly. Before starting a journey two simple checks can be made. Gentle pressure on the steering wheel, maintained while the engine is started, should result in a slight but noticeable movement as the system begins to operate. Alternatively turning the steering wheel just after moving off will give an immediate indication that the power assistance is functioning.
Operate brake pedal, make use of reflections in windows, garage doors, etc, or ask someone to help. As this is now a show me question the examiner may check the brake lights for you. You may need to switch the ignition on, however you should not start the engine.
Tyres should be checked to ensure there are no cuts or bulges. There should be 1.6mm of tread depth across the central ¾ of the breadth of the tyre and around the entire outer circumference. This can be checked with a tyre depth guage or the depth markers in the tyres themselves.
