Box Junction Rules
Yellow box junctions are marked with criss-cross yellow lines on the road. The rule is simple: do not enter the box unless your exit is clear. The exception is when turning right — you may wait in the box if your exit is blocked only by oncoming traffic or other vehicles waiting to turn right.
How Box Junction Fines Work
Box junction fines are issued by councils using CCTV cameras, typically £130 (reduced to £65 if paid within 14 days). The camera captures your vehicle entering the box and remaining stationary when the lights change. These are Penalty Charge Notices under the Traffic Management Act 2004.
Valid Grounds for Appeal
- Your exit was clear when you entered: If traffic ahead stopped unexpectedly after you entered the box, you didn't break the rule — the exit was clear when you entered.
- You were turning right: If you entered the box to turn right and were waiting for oncoming traffic, this is specifically permitted.
- The box markings were unclear: Faded or incomplete markings may mean the box junction was not properly designated.
- Emergency vehicle: If you stopped to let an emergency vehicle pass.
- The CCTV footage shows you were moving: If you didn't actually stop in the box (just passed through slowly), you didn't contravene the rule.
Request the CCTV Footage
Always request the CCTV footage from the council before appealing. The footage may actually support your case — showing you entered when the exit was clear, or that you were turning right.
