LGV Vehicle Safety Checks

Question 1

Before starting a journey, what fluid level must an LGV driver check under a daily walkaround check?

Accepted Answer

Engine oil, coolant, brake fluid, power steering fluid and screenwash

Answer

A thorough daily walkaround check includes checking all fluid levels: engine oil, coolant, brake fluid, power steering fluid, and screenwash. Low levels can cause mechanical failure on the road.

Question 2

How should an LGV driver check tyre pressure is correct?

Accepted Answer

Use a calibrated tyre pressure gauge when tyres are cold

Answer

Tyre pressure must be checked with a calibrated pressure gauge when tyres are cold (before driving). Visual checks alone are not sufficient as a tyre can lose significant pressure without appearing flat.

Question 3

What is the minimum legal tread depth for LGV (goods vehicle) tyres?

Accepted Answer

1 mm across the central three-quarters of the tread width

Answer

For goods vehicles, the minimum legal tread depth is 1 mm across the central three-quarters of the tread width, and the original tread pattern must be visible across the full width of the tyre.

Question 4

During a walkaround check, a driver notices a cracked windscreen. What should they do?

Accepted Answer

Report it to the transport manager and assess if it impairs vision before driving

Answer

A cracked windscreen must be reported immediately to the transport manager. If the crack is in the driver's field of vision (swept area of the wiper) or impairs visibility, the vehicle must not be driven until repaired.

Question 5

What should a driver check regarding the vehicle's lights during a daily inspection?

Accepted Answer

That all lights (including brake lights, indicators, and marker lights) function correctly

Answer

All lights must be checked: headlights, sidelights, brake lights, indicators, reversing lights, and any marker or hazard lights required for the vehicle. Faulty lights are a common roadside prohibition reason.
