Roundabout Lane Advice for HGV Drivers

Roundabouts can feel tricky when you’re behind a big rig. The right lane keeps you moving, saves fuel and stops you from breaking the law. Below you’ll find straight‑forward steps to pick the correct lane and drive through safely.

Know the Lane Layout Before You Enter

Look at the signs and road markings as you approach. In the UK most roundabouts have three basic lane options:

• Left‑hand lane – for exits soon after the entry point.
• Middle lane – for exits that are a few positions away.
• Outer/right‑hand lane – for the last exit or when you need to stay on the roundabout for a while.

For HGVs, the middle or outer lane is usually safer. The big vehicle needs more room to turn, and staying in the inner lane can force you to cut across traffic.

Pick the Right Lane for Your Exit

Match the lane to the exit you need:

• If you’re leaving at the first or second exit, stay left and keep a low speed.
• For exits three to five positions later, move into the middle lane early enough to avoid sudden lane changes.
• When you need the last exit, stay in the outer lane from the start. This keeps your turning radius comfortable and reduces the chance of hitting the central island.

Never jump lanes inside the roundabout. It disrupts flow and can cause other drivers to brake hard.

Remember to signal early – a 100‑metre warning is a good rule of thumb. HGVs need extra warning time because their mirrors and blind spots are larger.

Speed matters too. Heavy vehicles lose traction faster on wet surfaces, so aim for a steady 15‑20 mph inside the roundabout. That gives you control and helps you stay in your lane.

Finally, watch the traffic around you. If a car is already in your intended lane, give them space and wait for a safe gap. It’s better to stay a little longer in a wider lane than to squeeze in and cause an accident.

Following these simple lane choices makes roundabouts less stressful for you and everyone else on the road. Keep the tips in mind, and you’ll navigate roundabouts with confidence every time.
