LightsClean and working

LoadsSecure and not blocking view

Instructor insight

Vehicle safety checks can feel like memory work, but they are about spotting problems before they become dangerous.

Tyres, lights, mirrors, washers and warning lights all affect whether a journey is safe and legal.
Learners should understand what the check is for, not just remember the wording.
The driver is still responsible for the condition of the vehicle they use.

Know the daily checks you should make before driving: tyres, lights, mirrors, windscreen, wipers, and fluid levels.
Remember that you are legally responsible for the condition of the vehicle you are driving.
Know how to check tyre pressure and tread depth (minimum 1.6 mm across the central three-quarters).
Understand why you must check oil, coolant, brake fluid, and screenwash regularly.
Remember that faulty brakes, lights, or tyres can make you illegal to drive and dangerous.
Know that you should have the vehicle serviced according to the manufacturer's schedule.
Understand the importance of keeping windows and mirrors clean for good visibility.
In theory questions you may be asked what checks you should make or what is illegal to drive with.
Know that running out of fuel can damage some modern engines and is best avoided.
Vehicle safety checks are tested because an unroadworthy vehicle puts everyone at risk.

Theory-test study guidance - use these alongside the official Highway Code and plenty of practice questions.

Tyres must be legal and in good condition. Poor tyres reduce grip, increase stopping distance and make steering or braking less reliable.

Lights, indicators, mirrors and windows must be clean and working. If others cannot see you properly, the risk rises quickly.

Loads should be secure, balanced and not blocking your view. An unsafe load can affect handling and create danger for other road users.

Questions about vehicle checks are usually looking for responsibility before driving.
Tyres, lights and visibility are the biggest repeated themes.
If a load could move or block your view, it is not safe.

Why are tyre checks important?

Because tyres affect grip, braking, steering and overall control.

Who is responsible for vehicle condition?

The driver is responsible for making sure the vehicle is safe and legal to use.
