Navigating roundabouts

Roundabouts keep traffic flowing by removing the need for traffic lights at junctions. In the UK, traffic on the roundabout has priority, and you give way to vehicles approaching from your right.

The MSPSL routine

Apply this routine on approach to every roundabout:

• Mirrors. check what's behind and to your sides
• Signal. indicate your intended direction if necessary
• Position. move into the correct lane
• Speed. adjust your speed appropriately
• Look. assess the roundabout and traffic

Lane choice and signalling

Turning left (first exit)

• Signal left on approach
• Stay in the left lane
• Keep signalling left through the roundabout

Going straight ahead

• No signal on approach (unless road markings indicate)
• Usually left lane, but check road markings
• Signal left after passing the exit before yours

Turning right (third exit or beyond)

• Signal right on approach
• Use the right lane
• Stay in the right lane around the roundabout
• Signal left after passing the exit before yours
• Move to the left lane when safe before exiting

Spiral roundabouts

Some larger roundabouts have spiral lane markings. Follow them carefully. they guide you to the correct exit without needing to change lanes on the roundabout.

Mini roundabouts

Treat mini roundabouts the same as larger ones, but be aware that there's less space. Larger vehicles may need to drive over the painted circle.
