Give plenty of room to long vehicles on the roundabout as they need more space to manoeuvre. Do not ride in the space they need to get round the roundabout. It may be safer to wait until they have cleared the roundabout.
If you are turning right, you can ride in the left or right-hand lanes and move left when approaching your exit. Position yourself in the centre of your lane if it is safe to do so (see Rule 72) and signal right to indicate that you are not leaving the roundabout. Alternatively, you may feel safer walking your cycle round on the pavement or verge.
If you decide to ride round keeping to the left-hand lane you should
- be aware that drivers may not easily see you
- take extra care when cycling across exits. You should signal right to show you are not leaving the roundabout
- watch out for vehicles crossing your path to leave or join the roundabout.
Where a roundabout has separate cycle facilities, you should use these facilities where they make your journey safer and easier although you are not obliged to use them. This will depend on your experience and skills and the situation at the time.
Full details about the correct procedure at roundabouts without cycle facilities are contained in Rules 184 to 190.
Watch out for vehicles crossing your path to leave or join the roundabout, remembering that drivers may not easily see you.
Busy roads. When crossing faster or busy main roads, you may find it safer and easier to
- dismount and push your cycle across
- wait for a safe gap in the traffic before doing so, especially on faster roads and dual carriageways
- make use of traffic islands or central reservations to help you where appropriate.
Going straight ahead. If you are going straight ahead at a junction, you have priority over traffic waiting to turn into or out of the side road, unless road signs or markings indicate otherwise (see Rule H3). Check that you can proceed safely, particularly when approaching junctions on the left alongside stationary or slow-moving traffic. Watch out for drivers intending to turn across your path. Remember the driver ahead may not be able to see you, so bear in mind your speed and position in the road.
Take great care when deciding whether it is safe to pass stationary or slow-moving lorries and other long vehicles, especially at the approach to junctions, as their drivers may not be able to see you. Remember that they may have to move over to the right before turning left, and that their rear wheels may then come very close to the kerb while turning (see Rule 67).
