LGV Motorway Rules for LGVs 2

Question 1

What is the minimum distance rule when following another vehicle on a motorway?

Accepted Answer

Maintain a separation distance that allows you to stop safely — at least a 2-second gap in dry conditions, doubled in wet

Answer

The Highway Code recommends maintaining at least a 2-second gap (which should be doubled in wet conditions and increased significantly for heavy vehicles). LGV stopping distances are much greater than cars, so gaps should be larger.

Question 2

Under what circumstances can an LGV driver use lane 3 of a motorway?

Accepted Answer

Never — LGVs over 7.5 tonnes are prohibited from lane 3 at all times

Answer

LGVs over 7.5 tonnes are always prohibited from lane 3 on three-lane motorways, regardless of traffic conditions. There is no exception that allows a heavy lorry to use the outside lane.

Question 3

What action should an LGV driver take when approaching motorway roadworks with a lower speed limit displayed?

Accepted Answer

Comply with the speed limit — it is mandatory when shown on a matrix sign

Answer

Speed limits displayed on motorway matrix signs are legally enforceable mandatory limits, not advisory. LGV drivers must comply with the displayed limit in roadwork zones.

Question 4

On a motorway, what does a flashing amber light on an overhead gantry indicate?

Accepted Answer

A hazard ahead — reduce speed and prepare for slower traffic or obstruction

Answer

Flashing amber lights on motorway overhead gantries warn of a hazard ahead such as an accident, broken down vehicle, or queuing traffic. Drivers must reduce speed and be prepared to stop.

Question 5

What should an LGV driver do before joining a motorway from a slip road?

Accepted Answer

Build up speed in the acceleration lane and merge when safe, giving way to motorway traffic

Answer

On the acceleration lane, drivers should build up speed to match motorway traffic and find a safe gap to merge. Motorway traffic has priority — the joining driver must give way and should not force their way into traffic.
