Lane discipline on roundabouts

As a general rule if turning left or going straight ahead use the left hand lane, unless the road markings say otherwise.

If the exit displayed on the sign is past 12 oclock then consider it to be a right turn and therefore you would use the right hand lane.

The diagram below shows clearly which lane to use and how to signal on a standard roundabout.

Using roundabouts effectively is a vital skill for every driver, as there are more than 25,000 roundabouts across the UK, making them a common feature in daily driving. In this article, we simplify the rules and provide clear guidance to help you navigate any roundabout with confidence. Although roundabouts vary in size and complexity—from small urban mini roundabouts to large, intricate spiral designs—the fundamental rules remain consistent.

The MSM Routine: Approach with Confidence

As you approach a roundabout, the Mirrors – Signal – Manoeuvre (MSM) routine should always be used:

  1. Mirrors: Check all around.
  2. Signal: Indicate correctly if necessary.

Manoeuvre: Position according to your intended exit.

 Why Lane Discipline Matters

Proper lane discipline in and around roundabouts is vital for safety, and efficient traffic flow:

✅ Prevents Collisions

Cutting across lanes or drifting can lead to side-swipes or collisions, especially when visibility is limited or traffic is heavy.

✅ Reduces Confusion

Staying in the correct lane gives other drivers clear, predictable cues about your intentions, reducing any misunderstanding.

✅ Safety of vulnerable road users, Cyclists etc

Erratic lane changes can put vulnerable road users like pedestrians, cyclists, and motorcyclists at serious risk.

✅ Final Tips for Success

  • Plan early: Read signs well in advance.

     

  • Stay calm: Confidence comes with experience.
