LGV Vehicle Safety Checks 3

Question 1

What is the minimum air pressure required before an LGV may be driven?

Accepted Answer

The manufacturer's specified minimum operating pressure shown in the vehicle handbook

Answer

Air-braked LGVs must have sufficient air pressure before driving. The vehicle handbook specifies minimum operating pressure. Driving with insufficient air pressure can result in brake failure.

Question 2

A driver notices oil on the ground under the vehicle during the walkaround check. What action should be taken?

Accepted Answer

Investigate the source, do not drive the vehicle until the cause is identified and assessed

Answer

Oil on the ground under a vehicle could indicate a serious leak from the engine, transmission, or braking system. The driver must identify the source before driving. A hydraulic brake fluid leak could be life-threatening.

Question 3

What is checked when a driver tests the operation of the windscreen wipers?

Accepted Answer

That wipers clear the screen effectively, are not damaged, and the washer fluid operates

Answer

Wiper operation should include checking that the blades are not damaged or worn (which causes smearing), that they cover the swept area properly, and that the washer jets work and screenwash is at an adequate level.

Question 4

What is a 'prohibition notice' issued by DVSA?

Accepted Answer

A legal order preventing the vehicle from being driven until the defect is rectified

Answer

A prohibition notice (S.9 or PG9) is issued by a DVSA examiner when a vehicle has a serious defect. An immediate prohibition means the vehicle cannot be moved. A delayed prohibition allows driving back to the operator's premises only.

Question 5

How often must an LGV undergo a statutory annual test (MOT)?

Accepted Answer

Every 12 months (vehicles over 3.5 tonnes MAM)

Answer

Goods vehicles over 3.5 tonnes maximum authorised mass must pass an annual test (MOT) every 12 months. The vehicle must not be used on public roads without a valid test certificate.
