LGV Vehicle Weights and Dimensions 2

Question 1

What is the maximum gross train weight for a 6-axle articulated vehicle in the UK?

Accepted Answer

44 tonnes

Answer

A 6-axle articulated vehicle can operate at up to 44 tonnes gross train weight in the UK, provided it meets specific axle spacing and configuration requirements. A 5-axle artic is limited to 40 tonnes.

Question 2

What is the maximum rear overhang permitted on a rigid HGV?

Accepted Answer

60% of the wheelbase

Answer

The maximum rear overhang on a rigid vehicle must not exceed 60% of the wheelbase. This ensures the vehicle remains stable and that the rear overhang does not create excessive sweep during turns.

Question 3

Why is it important to know the kerb weight of your vehicle?

Accepted Answer

It is subtracted from the maximum gross weight to determine the payload capacity

Answer

The kerb weight (the vehicle's weight when empty but with full tanks, oil, coolant, and standard equipment) must be subtracted from the maximum gross vehicle weight to determine how much payload can be carried. Overloading is illegal and dangerous.

Question 4

What is a bridge authority notification and when is it needed?

Accepted Answer

It is required when a vehicle's weight, width, or length exceeds normal limits and it needs to cross certain bridges

Answer

Bridge authority notification is required for abnormal loads that exceed standard weight or dimension limits. Some historic and weight-restricted bridges also require notification for vehicles within normal limits if they exceed the bridge's specific restrictions.

Question 5

What does 'design weight' on a plating certificate mean?

Accepted Answer

The maximum weight the vehicle's components are designed to handle, which may exceed the legal maximum

Answer

The design weight is the maximum weight the vehicle's mechanical components (chassis, axles, brakes) are engineered to handle. This may be higher than the legally permitted maximum weight, as legal limits consider road and bridge capacity, not just vehicle capability.
