Highway Code Rule 76
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).

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.
