13. Vehicle safety check questions
Vehicle safety questions ('show me, tell me' questions) used by driving examiners in car driving tests, motorcycle tests, vocational driving tests, and tractor and specialist vehicle driving tests (including Highway Code questions).
Tell me questions
T1: Tell me how you would check that the brakes are working before starting a journey.
A: Brakes should not feel spongy or slack. Brakes should be tested as you set off. Vehicle should not pull to one side.
T2: Tell me where you would find the information for the recommended tyre pressures for this car and how tyre pressures should be checked.
A: Manufacturer’s guide, use a reliable pressure gauge, check and adjust pressures when tyres are cold, don’t forget spare tyre, remember to refit valve caps.
T3: Tell me how you make sure your head restraint is correctly adjusted so it provides the best protection in the event of a crash.
A: The head restraint should be adjusted so the rigid part of the head restraint is at least as high as the eye or top of the ears, and as close to the back of the head as is comfortable. Note: Some restraints might not be adjustable.
T4: Tell me how you would check the tyres to ensure that they have sufficient tread depth and that their general condition is safe to use on the road.
A: No cuts and bulges, 1.6mm of tread depth across the central 3/4 of the breadth of the tyre and around the entire outer circumference.
T5: Tell me how you would check that the headlights & tail lights are working. (No need to exit vehicle)
A: Explanation: Operate switch (turn on ignition if necessary), then walk round vehicle. (As this is a “Tell Me” question, there is no need to physically check the lights).
T6: Tell me how you would know if there was a problem with your anti-lock braking system.
A: Warning light should illuminate if there is a fault with the anti-lock braking system.
T7: Tell me how you would check the direction indicators are working. (No need to exit the vehicle)
A: Explanation: Operate switch (turn on ignition if necessary), then walk round vehicle. (As this is a “Tell Me” question, there is no need to physically check the lights).
T8: Tell me how you would check the brake lights are working on this car.
A: Explanation: Operate brake pedal, make use of reflections in windows, garage doors, etc., or ask someone to help.
T9: Tell me how you would check the power assisted steering is working before starting a journey.
A: Explanation: 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.
T10: Tell me how you would switch on the rear fog light(s) and explain when you would use it/them, (no need to exit vehicle).

A: Operate switch (with ignition or engine on if necessary), check with main beam warning light.
T12: Open the bonnet and tell me how you would check that the engine has sufficient oil.
A: Identify dipstick / oil level indicator, describe check of oil level against the minimum/ maximum markers.
T13: Open the bonnet and tell me how you would check that the engine has sufficient engine coolant.
A: Identify high/low level markings on header tank where fitted or radiator filler cap, and describe how to top up to correct level.
T14: Open the bonnet and tell me how you would check that you have a safe level of hydraulic brake fluid.
