Who is responsible for ensuring that passengers under 14 wear seat belts or use the correct restraint?
Answer: The driver
Drivers must make sure children under 14 are properly restrained. Adults over 14 are responsible for their own belts.
You see a warning light on your dashboard. What should you do?
Answer: Check your handbook and act on it promptly
Warning lights can show serious faults, such as with brakes or oil pressure. Never ignore them.
What should you do before starting a long journey?
Answer: Check your oil, coolant, washer fluid, tyres and lights
Regular checks help prevent breakdowns and keep you legal and safe.
When should you use front or rear fog lights?
Answer: When visibility is seriously reduced, generally less than 100 metres
Switch them off once visibility improves, as they can dazzle others and hide your brake lights.
What is the legal minimum tread depth for car tyres?
Answer: 1.6 mm across the central three-quarters of the tread, around the whole tyre
Tyres below 1.6 mm are illegal and lose grip quickly in the wet.
When should you check your tyre pressures?
Answer: When the tyres are cold, including the spare
Driving warms tyres and raises the pressure, giving a false reading.
What are the effects of under-inflated tyres?
Answer: Poor handling, extra fuel use and faster tyre wear
Soft tyres flex too much, which heats them up and wastes fuel.
You find a bulge in the side of a tyre. What should you do?
Answer: Have it replaced before you drive any further
A bulge shows the tyre structure has failed and it may burst.
Which fluid levels should you check regularly?
Answer: Engine oil, coolant, brake fluid and screen wash
Regular checks catch problems early and keep the car safe.
Your oil pressure warning light comes on while driving. What should you do?
Answer: Stop safely as soon as you can, switch off and check the oil level
Driving without oil pressure can wreck the engine in minutes.
