Roundabouts are designed to keep the traffic flowing. Traffic should only flow in a clockwise direction around the island in the centre of the roundabout. This circular road is a one-way street and may be made up of one or more lanes. Mini roundabouts are much smaller but have the same purpose to keep the traffic flowing. Traffic entering the roundabout must give way to traffic already on the roundabout approaching from the right.
Approaching a roundabout
When approaching a roundabout you apply your Hazard Drill and take observations into the major road ahead as early as possible. Unlike other junctions most roundabouts are quite open so that you can assess the flow of traffic on the roundabout at an early stage. This should give enough time to adjust your speed so that, if possible, you can emerge safely into the flow of traffic from the right without stopping.
Some drivers use roundabouts as though they were stop junctions and only take observations to the right at the last minute. As a result they might stop at the give way line when it is not necessary. Therefore do not presume the vehicle in front will proceed, even if it is clear.
This video shows you how to watch for other vehicles on or approaching the roundabout and whether to stop or go.
