What is a box junction?
A box junction is an area in the centre of a junction, usually at a busy crossroads or T-junction, where the road is marked with a yellow criss-crossed box. They are there as traffic control measures, to prevent gridlock at junctions. Box junctions are often also controlled by traffic lights, but this won’t always be the case so keep your eyes on the road markings and make sure you’re up to scratch on your box junction rules.
What are the rules for a box junction?
1. Do not enter a box junction unless the exit road is clear
2. Only stop in the box if you’re turning right and waiting for a gap in traffic
3. If the traffic lights go red before you turn, you’re still allowed to make the turn
4. Blocking a box junction is illegal and could land you with a fine
When may you enter a box junction?
You should not enter a box junction unless the exit road is clear. Even if the traffic lights are green, you should wait until you can be sure there’s a clear path to get to the exit you want to go down.

This isn’t something you want to misjudge, so it’s best to be cautious! Plus, it goes without saying that you shouldn’t enter if the traffic lights are on red.
