When turning

• keep as close to the left as is safe and practicable
• give way to any vehicles using a bus lane, cycle lane, cycle track or tramway from either direction, including when they are passing slow moving or stationary vehicles on either side.

Use your mirrors and give a left-turn signal well before you turn left. Do not overtake just before you turn left and watch out for traffic coming up on your left before you make the turn, especially if driving a large vehicle. Cyclists, motorcyclists and other road users in particular may be hidden from your view.

When turning right at crossroads where an oncoming vehicle is also turning right, there is a choice of two methods

• turn right side to right side; keep the other vehicle on your right and turn behind it. This is generally the safer method as you have a clear view of any approaching traffic when completing your turn
• left side to left side, turning in front of each other. This can block your view of oncoming vehicles, so take extra care. Cyclists and motorcyclists in particular may be hidden from your view. Road layout, markings or how the other vehicle is positioned can determine which course should be taken.

Wait until there is a safe gap between you and any oncoming vehicle. Watch out for cyclists, motorcyclists, pedestrians and other road users. Check your mirrors and blind spot again to make sure you are not being overtaken, then make the turn. Do not cut the corner. Take great care when turning into a main road; you will need to watch for traffic in both directions and wait for a safe gap.

Remember: Mirrors – Signal – Manoeuvre

Well before you turn right you should

• use your mirrors to make sure you know the position and movement of traffic behind you
• give a right-turn signal
• take up a position just left of the middle of the road or in the space marked for traffic turning right
• leave room for other vehicles to pass on the left, if possible.

Advanced stop lines. Some signal-controlled junctions have advanced stop lines to allow cyclists to be positioned ahead of other traffic. Motorists, including motorcyclists, MUST stop at the first white line reached if the lights are amber or red and should avoid blocking the way or encroaching on the marked area at other times, e.g. if the junction ahead is blocked. If your vehicle has proceeded over the first white line at the time that the signal goes red, you should stop as soon as possible and MUST stop at the second white line. Allow cyclists, including any moving or waiting alongside you, enough time and space to move off when the green signal shows.

Drivers of large vehicles should stop sufficiently far behind the first white line so that they can see the whole area where cyclists may be waiting, allowing for any blind spot in front of the vehicle.

Green filter arrow. This indicates a filter lane only. Do not enter that lane unless you want to go in the direction of the arrow. You may proceed in the direction of the green arrow when it, or the full green light shows. Give other traffic, especially cyclists, time and room to move into the correct lane.

You MUST NOT move forward over the white line when the red light is showing. Only go forward when the traffic lights are green if there is room for you to clear the junction safely or you are taking up a position to turn right. If the traffic lights are not working, treat the situation as you would an unmarked junction and proceed with great care.

Laws RTA 1988 sect 36 & TSRGD regs 10 & 36

You MUST stop behind the white ‘Stop’ line across your side of the road unless the light is green. If the amber light appears you may go on only if you have already crossed the stop line or are so close to it that to stop might cause a collision.

Laws RTA 1988 sect 36 & TSRGD regs 10 & 36

Box junctions. These have criss-cross yellow lines painted on the road (see ‘Road markings’). You MUST NOT enter the box until your exit road or lane is clear. However, you may enter the box and wait when you want to turn right, and are only stopped from doing so by oncoming traffic, or by other vehicles waiting to turn right. At signalled roundabouts you MUST NOT enter the box unless you can cross over it completely without stopping.
