LGV Motorway Rules for LGVs 4

Question 1

What is the safe driving technique for an LGV on a motorway in heavy spray conditions?

Accepted Answer

Increase following distance significantly, use headlights, and reduce speed proportionally to visibility

Answer

Heavy spray dramatically reduces visibility and can obscure the road surface. LGV drivers should increase following distances (already larger than for cars), use headlights, reduce speed to match visibility, and avoid fog lights unless visibility falls below 100 metres.

Question 2

When is it legal to use the hard shoulder as a driving lane on a motorway?

Accepted Answer

Only on smart motorways where the hard shoulder is opened with a speed limit sign above it

Answer

On smart motorways running in ATM mode, the hard shoulder may be opened as an additional lane when indicated by a speed limit sign on the overhead gantry above it. Without such a sign, the hard shoulder must not be used as a running lane.

Question 3

What does a motorway sign with the distance '100 yds' above a diagonal arrow pointing left mean?

Accepted Answer

Leave the motorway or move left — the junction or service area is 100 yards ahead

Answer

Countdown markers with distances (usually 300, 200, 100 yards) before a motorway exit show how far it is to the slip road. Drivers should be in lane 1 well before the exit and use these to position correctly.

Question 4

What is the correct response when a driver sees a signal showing '50' on a motorway matrix above a lane?

Accepted Answer

Reduce speed to 50 mph — it is a mandatory speed limit

Answer

A speed limit shown on a motorway overhead sign (matrix) is a mandatory limit when accompanied by a red ring (or on a smart motorway). LGV drivers must comply even if the road appears clear, as the limit may be due to an unseen hazard.

Question 5

What does a white rectangular sign reading 'END' on a motorway overhead gantry mean?

Accepted Answer

The variable speed limit or motorway restriction ends at that point

Answer

An 'END' sign on a motorway gantry indicates that a variable speed restriction or mandatory requirement (such as a reduced speed limit in a roadwork zone) has ended. Normal motorway rules and limits resume.
