UK Roundabouts Explained: Approach, Signal, Position
The full theory-test guide to normal, mini and multi-lane roundabouts — with the signalling rules learners most often get wrong.
Roundabouts are a favourite of DVSA question writers because they combine priority, lane discipline and signalling. Get the pattern below into your head and roundabout questions become almost automatic.
The universal rule
Give way to traffic coming from your right, unless road markings or signals say otherwise. That's it — that's the core rule.
Approaching: MSPSL
Mirrors, Signal, Position, Speed, Look. In that order, every time.
Choosing a lane on a normal roundabout
- Turning left (first exit) — left lane, left signal on approach, keep it on until you exit.
- Going straight ahead (usually 2nd exit) — left lane, no signal on approach, signal LEFT after you pass the exit before yours.
- Turning right or full circle (past 12 o'clock) — right lane, right signal on approach, change to left signal after passing the exit before yours.
Mini roundabouts
Same rules — give way to the right — but there's less room to manoeuvre. You must pass round the central white marking (not over it) whenever possible. Signal your intention just like a normal roundabout.
Multi-lane and spiral roundabouts
Follow the road markings and lane arrows painted on approach. On a spiral roundabout, your lane naturally spirals outwards to the correct exit — don't fight the markings by changing lanes.
Watching for cyclists and horse riders
Cyclists and horse riders often stay in the left lane whichever exit they're taking. Give them room, watch for their signals, and expect them to move across in front of you as they approach their exit.
Common test-question traps
- 'You should signal left as you pass the exit before the one you want' — true, even if going straight ahead.
- 'Long vehicles may need to take a different course' — true; give them extra room and don't assume their signal.
- 'Mini-roundabouts have the same priority rules as normal ones' — true.
