Do not go forward when traffic lights are green unless you are sure there is room to clear the junction safely. You must not go forward under red lights or when the red and amber lights are showing together.

Where traffic lights show a green arrow filter signal, do not get into the lane where filtering is allowed unless you want to go in the direction shown by the arrow.

Give way to pedestrians crossing or look out for pedestrians waiting to cross the road into which you are turning.

If traffic lights are not working, slow down or even stop as necessary, treat the junction as a non-signalised junction and proceed through the junction with extreme caution.

When you cannot go forward you must wait behind the ʻStopʼ line.

Box junctions

illustration

You must not enter the box if the exit road or lane from it is not clear.

You may however enter the box from a right-turn lane marked with 'Turn right' arrows if you want to turn right but are prevented from doing so by oncoming traffic or by other vehicles waiting to turn right.

Tram and North-west railway (light rail) crossing box junctions

illustration Where a road junction is crossed by tram tracks or light rail tracks and is marked with the crossing box marking, you must not enter the box junction from any approach lane, including a right-turn lane, unless the exit is clear.
