Yellow box junctions
Yellow box junctions, loading bays and red routes are in place to keep traffic on the roads flowing. Our priority is to keep London moving and reduce delays, not raising revenue through fines. We are trying to help people understand the rules of the road so that they avoid an unnecessary fine.
Yellow box junctions are indicated by criss-cross yellow lines painted on the road. They are usually found at the junction of two or more roads and occasionally at roundabouts or outside fire and ambulance stations. A yellow box junction does not require any other signage.
How to use a yellow box junction
You may enter a yellow box junction when your exit is clear and there is enough space on the other side of the junction for your vehicle to clear the box completely without stopping.
You can stop in a yellow box junction when turning right if you are prevented from turning by oncoming traffic, or by other vehicles waiting to turn right.
Do not simply follow the vehicle in front as it may stop and prevent your exit and don't let other drivers pressure you to enter the box when a clear exit is not available.
Only enter a box junction if your exit road is clear
Penalty Charge Notices (PCNs)
We issue Penalty Charge Notices (PCN) to deter drivers from breaking the rules and causing a traffic jam. We don't simply issue PCNs to raise revenue - we enforce the rules to help keep the traffic moving.
