Question 1

What does an amber warning light on an HGV dashboard typically indicate?

Accepted Answer

An advisory or developing issue that needs attention soon

Answer

Amber warning lights indicate an advisory condition or developing fault that needs attention soon but may not require immediate stopping. Red warning lights indicate critical failures requiring immediate action.

Question 2

Why is it important to check mirrors and camera systems before moving off?

Accepted Answer

To identify vulnerable road users such as cyclists and pedestrians in blind spots

Answer

HGVs have significant blind spots. Checking mirrors and camera systems before moving off is essential to identify vulnerable road users — particularly cyclists and pedestrians — who may be in these blind spots. Failure to do so has caused numerous fatal incidents.

Question 3

What is the purpose of the HGV's secondary braking system?

Accepted Answer

To provide braking if the main service brake fails

Answer

The secondary braking system provides an alternative means of stopping the vehicle if the main service brake fails. It must be capable of slowing and stopping the vehicle safely, though with reduced efficiency.

Question 4

What should a driver check regarding wheel fixings during a walkaround?

Accepted Answer

That wheel nuts are present, properly tightened, and there are no signs of loosening

Answer

Drivers should check that all wheel nuts are present, properly tightened, and show no signs of loosening such as rust staining or movement indicators being misaligned. Loose wheels are a serious hazard that can cause fatal incidents.

Question 5

When should marker lights and reflectors be checked on an HGV?

Accepted Answer

During every daily walkaround check

Answer

Marker lights and reflectors should be checked during every daily walkaround check. They are essential for making the vehicle visible to other road users, especially in poor light conditions, and defective lighting is a common prohibition item.
