Lane Discipline for HGV Drivers – Why It Matters and How to Do It Right

Driving a heavy goods vehicle (HGV) feels different from a car. You’re bigger, slower to stop, and you take up more space. Because of that, keeping to your lane is not just good manners – it’s a safety rule. In the UK, lane discipline helps you avoid accidents, saves fuel, and keeps you clear of fines.

First, understand the basic rule: stay in the lane that matches your speed and the type of road. On motorways, HGVs should use the right‑hand lane unless they need to overtake. On dual carriageways, the same rule applies, but you can use the left lane for short overtakes if it’s safe.

Key UK Lane Rules for HGVs

1. Motorways: Stay in the middle or right lane. The left lane is for faster traffic and emergency vehicles. If you need to pass, signal, check mirrors, and move back quickly.

2. Dual carriageways: Use the left lane only for overtaking. After passing, return to the right-hand lane as soon as possible.

3. Single carriageways: Keep to the right side of the road. If the road is narrow, you may need to stay close to the centre line, but never cross the centre unless you’re turning.

4. Roundabouts: Stay in the lane that matches your exit. Most HGVs should use the outer lane and give way to traffic already on the roundabout.

5. Lane markings: Follow solid lines – you can’t cross them. Broken lines let you change lanes, but only when it’s safe.

Practical Tips to Keep Your Lane Discipline Sharp

• Check mirrors constantly. HGV mirrors give a wide view, but blind spots are still there. Glance at the left, right, and centre mirrors every few seconds.

• Use your indicators early. Give other drivers at least 3 seconds to react before you change lanes.

• Plan overtakes. Look ahead for a clear stretch, signal, and accelerate smoothly. Don’t squeeze into a narrow gap.

• Maintain speed. Driving too slow forces faster traffic to weave around you, increasing the risk of accidents.

• Watch road signs. Speed limits, lane use signs, and HGV restrictions are posted frequently. Ignoring them can lead to fines and dangerous situations.

Keeping lane discipline is a habit. Start each journey by scanning the road, noting where you’ll need to stay or move. If you feel unsure, pull over safely and review the route.

Remember, a disciplined lane approach protects you, your cargo, and everyone else on the road. Stick to the rules, use the tips above, and you’ll find driving an HGV smoother and safer.
