“At roundabouts, going ahead means the second exit or a subsequent exit that is directly ahead or less than halfway around the roundabout. This means that if you are entering at Road A, Roads C & D would both normally be considered as going head.
As with left turns, start your approach by checking your mirrors but, unlike left turns, you won’t be giving a signal on the approach.
Keep to the left lane and follow the same initial routine as if turning left, visually scanning the road ahead and to the right in order to keep a good road position and to look for a gap in the traffic.
Where there are three or more lanes on approach, the left lane might be for left turning traffic only. In these situations, look out for road markings that indicate which approach lane to take for your destination.
When you are 100% sure that there is a clear road or that there is a suitable gap in the traffic, enter the roundabout. Keep to the left lane as you drive around the roundabout, unless markings indicate otherwise.
Signal left to leave the roundabout as you are passing or have passed the exit before the one you wish to take. The exact timing will depend on the size and layout of the roundabout.
Keep your signal on as you exit and then check your mirrors and cancel the signal after the exit. The key points are:
– Check your mirrors early and then maek further checks as you approach
– Give way to traffic from the right
– No signal on the approach and keep to the left hand lane or marked lane for your destination
– Keep left as you drive around the roundabout
– Signal left when you pass the exit before the road you wish to take
– Check your mirrors and cancel the signal after you leave the roundabout”
