LGV Hazard Perception

Question 1

What is 'hazard perception' in the context of LGV driving?

Accepted Answer

The skill of identifying and responding to developing hazards early enough to take safe action

Answer

Hazard perception is the ability to scan the road environment, identify potential hazards (situations that may require a change in speed or direction), and respond early enough to take appropriate, safe action. It is a critical skill tested in the LGV theory test.

Question 2

When approaching a school at the end of the day, what hazards should an LGV driver anticipate?

Accepted Answer

Children running into the road, parked vehicles reducing visibility, parents doing U-turns, and crossing patrols

Answer

Near schools, LGV drivers should anticipate children running into the road from between parked cars, reduced visibility from parked vehicles, parents making unexpected manoeuvres, crossing patrols, and icy patches near school entrances in winter.

Question 3

What is the 'two-second rule' used for in hazard perception?

Accepted Answer

A method to maintain a safe following distance in good conditions — increased for HGVs and poor weather

Answer

The two-second rule helps maintain a safe following distance: pick a fixed point and count at least two seconds between the vehicle ahead passing it and your vehicle reaching it. For HGVs, this should be increased, and in wet/poor conditions, doubled or more.

Question 4

Why are bends particularly hazardous for LGV drivers?

Accepted Answer

The vehicle's length means the rear may cut across the opposite lane or verge, and visibility ahead is limited

Answer

LGVs have significant rear cut-in on bends, meaning the trailer tracks inside the tractor's path. This can cause the rear to clip verges, cyclists, or cross into the opposite lane. Additionally, forward visibility is reduced on bends, hiding potential hazards.

Question 5

What technique should an LGV driver use to scan for hazards effectively?

Accepted Answer

Use systematic scanning: far distance, middle distance, near distance, and mirrors, in a continuous cycle

Answer

Effective scanning involves continuously cycling attention between the far distance (traffic flow, road layout), middle distance (developing situations), near distance (immediate surroundings), and mirrors (what is happening alongside and behind). This 360-degree awareness is essential.
