LGV Motorway Rules for LGVs

Question 1

Which lanes of a three-lane motorway are LGVs over 7.5 tonnes permitted to use?

Accepted Answer

Lanes 1 and 2 only

Answer

LGVs exceeding 7.5 tonnes are prohibited from using lane 3 (the outside lane) on motorways with three or more lanes. They may travel in lanes 1 and 2, and must return to lane 1 when not overtaking.

Question 2

What is the maximum speed for an LGV over 7.5 tonnes on a motorway?

Accepted Answer

60 mph

Answer

LGVs over 7.5 tonnes are restricted to 60 mph on motorways. Despite the general motorway limit being 70 mph, heavy goods vehicles are subject to a lower maximum speed limit.

Question 3

What does a motorway matrix sign showing a red X above a lane mean?

Accepted Answer

That lane is closed — you must not drive in it

Answer

A red X on a motorway matrix sign (overhead gantry) means the lane is closed and must not be used. Driving in a lane with a red X displayed is illegal and dangerous.

Question 4

What should an LGV driver do if their vehicle breaks down on a motorway?

Accepted Answer

Move to the hard shoulder if possible, switch on hazard lights, exit via the nearside, call for assistance from the emergency telephone

Answer

On a motorway breakdown, pull onto the hard shoulder if possible, position the vehicle near an emergency telephone, switch on hazard lights, exit the vehicle from the nearside (left side), move to the bank beyond the barrier, and use the roadside emergency telephone.

Question 5

What is the purpose of 'smart motorway' running in Active Traffic Management (ATM) mode?

Accepted Answer

To use the hard shoulder as a running lane to increase capacity and manage traffic flow

Answer

In Active Traffic Management (ATM) mode, the hard shoulder is opened as a running lane to increase capacity. Variable speed limits and lane signals are used to manage flow. LGV drivers must comply with all overhead signals.
