When approaching a roundabout take advantage of the fact that most are open junctions and you can see onto the junction from well back. Glance at the roundabout and then in front several times on the approach to assess the traffic and adjust your speed so you can feed in if possible.
Priority on approach – When approaching the vast majority of roundabouts, you will give way to traffic coming from the right. There will be rare occasions when the give way line is on the roundabout itself and you can enter the roundabout with priority.
Position on approach – Position left for turning left and going ahead, right for turning right unless road markings, signs or road layout direct otherwise. You may use the right-hand lane for going ahead if the road markings indicate. With three unmarked lanes use the left lane for left, middle for going ahead and right lane for turning right.
Position on the roundabout – Unless directed otherwise use the left lane for turning left and going ahead. Right lane for turning right. You may use the right-hand lane for going ahead if markings indicate. If there are more than three lanes, then follow the road markings.
Exiting a roundabout – Check your mirrors and indicate as you pass the previous exit to the exit you’re taking. Finally, check your left side mirror before leaving the roundabout in the left-hand lane. If the left lane is not available, then take the right. Having exited the roundabout in the right-hand lane make your way into the left-hand lane at the earliest safe opportunity.
