Yellow box junctions are among the most misunderstood road markings on UK roads. Many drivers are unsure about when it is legal to stop inside these painted boxes, leading to frequent traffic blockages and, soon, fines.
At Junction 1 of the M5 in West Bromwich, cameras are being installed to monitor compliance, with enforcement set to begin soon. This move aims to reduce congestion and improve traffic flow in this busy area.
Yellow box junctions—marked by criss-cross yellow lines—are designed to keep intersections clear. They are typically placed where traffic queues can easily build up, such as roundabouts or traffic light junctions. Drivers must not enter the yellow box unless their exit on the other side is clear, preventing them from stopping and blocking the way.

A common mistake occurs when drivers follow the car ahead into the box without ensuring the road beyond is free, resulting in gridlock. However, there is one exception: drivers waiting to make a right turn can legally stop inside the yellow box while waiting for oncoming traffic to clear.
Sandwell Council has confirmed plans to begin enforcement against yellow box offences on the A41 near the M5 Junction in West Bromwich. Although the exact start date has not yet been announced, motorists should prepare for increased monitoring and potential fines.
Understanding these rules is crucial for smoother traffic and avoiding penalties. Remember: only enter a yellow box if you are sure you can clear it completely—unless you are waiting to turn right.
