Question 1

What is the speed limit for an HGV over 7.5 tonnes on a single carriageway in England and Wales?

Accepted Answer

50 mph

Answer

The speed limit for HGVs over 7.5 tonnes on single carriageways in England and Wales is 50 mph. This is lower than the 60 mph limit for cars on the same roads, reflecting the longer stopping distances of heavy vehicles.

Question 2

When driving an HGV in heavy rain, what should the driver do?

Accepted Answer

Increase following distance and reduce speed to account for longer stopping distances

Answer

In heavy rain, stopping distances can double. Drivers should increase their following distance, reduce speed, and ensure lights and wipers are on. Spray from HGVs can severely reduce visibility for following vehicles.

Question 3

What is the main danger when an HGV driver is overtaking a cyclist?

Accepted Answer

The HGV's blind spots and air displacement can pull the cyclist towards the vehicle

Answer

HGVs create significant air displacement that can pull cyclists towards the vehicle. Combined with large blind spots, this makes overtaking cyclists extremely dangerous. Drivers must leave at least 1.5 metres of space and reduce speed.

Question 4

What does the Highway Code recommend as a safe following distance in good conditions?

Accepted Answer

At least a two-second gap (more for larger vehicles)

Answer

The Highway Code recommends at least a two-second gap in good conditions, with this gap increased significantly for larger vehicles due to their longer stopping distances. In wet conditions, the gap should be doubled, and in icy conditions, multiplied by ten.

Question 5

Why are roundabouts particularly hazardous for HGV drivers?

Accepted Answer

The vehicle's length requires using more than one lane, creating blind spot risks for other road users

Answer

HGVs often need to straddle lanes on roundabouts due to their length and turning radius. This creates significant blind spot risks, particularly for cyclists and motorcyclists who may be alongside. Drivers must use mirrors extensively and signal clearly.
