AThe general rule is to give way. With
the entry to a roundabout marked by a single broken white line, vehicles entering a roundabout should give way to vehicles already on it. For this purpose a roundabout means a junction where traffic moves one way round a central island.
There are four exceptions to this rule: where there is two-way traffic along one side or part of a side: islands with permanent buildings on them around which there is oneway traffic; large islands set out as gardens or recreational areas: small circular guide islands in the centre of dual carriageways.
At Y junctions where there is a roundabout and where roads enter and leave without changing direction, broken double white lines indicate that traffic on the roundabout should give way to traffic entering it.
