Before driving with a trailer, the driver must physically check that the kingpin coupling is fully engaged with the fifth wheel, safety locks (jaws) are closed, trailer brake airline and electrical connections are secure, and trailer legs are fully raised.

Question 2

How should a driver check that the vehicle's brakes are working correctly before a journey?

Accepted Answer

Conduct a brake test at low speed in a safe area, checking for pulling or unusual noises

Answer

A basic brake check at low speed in a safe area should be performed, feeling for any pulling to one side, sponginess, or unusual noises. Air pressure gauges should also be checked for correct pressure. Any concerns must be reported.

Question 3

What does an amber ABS warning light on the dashboard indicate?

Accepted Answer

The ABS system has detected a fault and is disabled on that axle or the whole system

Answer

An illuminated amber ABS warning light indicates a fault in the anti-lock braking system. The standard brakes may still work, but ABS protection is reduced or lost. The fault must be investigated and repaired promptly.

Question 4

What must a driver check regarding the vehicle's steering?

Accepted Answer

Check for excessive free play by turning the wheel gently and feeling resistance

Answer

Before driving, a driver should check for excessive free play in the steering wheel. Any looseness or play beyond the normal small amount indicates a potential steering problem that must be reported.

Question 5

Why must a driver check the vehicle's mirrors before departure?

Accepted Answer

To ensure they are correctly adjusted to give maximum field of view and are clean and undamaged

Answer

Mirrors must be adjusted for the driver's position and height before every journey. They must also be clean and free from cracks or distortion. Poorly adjusted mirrors create blind spots that can lead to collisions.
