Rule 211 - The Highway Code

It is often difficult to see motorcyclists and cyclists, especially when they are waiting alongside you, coming up from behind, coming out of or moving off from junctions, at roundabouts, overtaking you or filtering through traffic. Always look out for them before you emerge from a junction; they could be approaching faster than you think.

Do not turn at a junction if to do so would cause the cyclist going straight ahead to stop or swerve, just as you would do with a motor vehicle.

When turning right across a line of slow-moving or stationary traffic, look out for and give way to cyclists or motorcyclists on the inside of the traffic you are crossing. Be especially careful when moving off, turning, and when changing direction or lane. Be sure to check mirrors and blind spots carefully.
