How to Appeal a Bus Lane Fine UK 2026
Bus lane fines are one of the most commonly issued PCNs in the UK, yet many are issued incorrectly. Unclear signage, incorrect restricted hours, and procedural failures by councils mean a significant number of bus lane PCNs can be successfully challenged. This guide explains how.

Bus lane enforcement is a civil matter, not a criminal one. Councils use CCTV cameras to capture vehicles driving in bus lanes during restricted hours and issue Penalty Charge Notices (PCNs) under the Traffic Management Act 2004. In London, TfL enforces bus lanes under the London Local Authorities and Transport for London Act 2003.
The most common defence: signage
Bus lane signs must comply with the Traffic Signs Regulations and General Directions 2016 (TSRGD 2016). Signs must be clearly visible, unobscured, include the restricted hours, and provide adequate advance warning. If signs are missing, damaged, obscured by vegetation, or non-compliant with TSRGD 2016, the PCN may be invalid.
Restricted hours defence
Many bus lanes only operate during specific hours (e.g., Mon-Sat 7am-7pm). If you drove in the bus lane outside those restricted hours, there is no contravention. Check the times on the sign carefully and compare with the timestamp on your PCN.
Other strong grounds for appeal
- Forced into the bus lane by traffic, roadworks, or an emergency vehicle
- Vehicle broke down and you had no choice but to stop in the bus lane
- Turning left at a junction and briefly using the bus lane as permitted
- Dropping off or picking up a passenger (some bus lanes allow this)
- Your vehicle is exempt (taxi, hackney carriage, emergency vehicle)
- PCN served outside the statutory time limit (28 days for postal PCNs)
How to make a formal representation
To challenge a bus lane PCN, you must submit a formal representation in writing to the issuing authority within 28 days. Your letter should identify the PCN by reference number, state your grounds clearly, cite the relevant legislation, and include any evidence. The council must respond. If they reject your representation, you can escalate to the Traffic Penalty Tribunal (outside London) or London Tribunals (in London) — both are free.
PCN timing rules
A postal PCN must be served within 28 days of the alleged contravention. If it was served late, this is a strong procedural defence. An on-vehicle PCN must be affixed at the time. Keep the PCN envelope as evidence of the delivery date.
What happens if you escalate to the tribunal?
The Traffic Penalty Tribunal (or London Tribunals) is an independent body. You can appeal online, by post, or in person. The adjudicator reviews the council's evidence and your defence. If the signage was non-compliant, the PCN was late, or the council cannot prove the contravention, the PCN is cancelled. There is no cost to appeal.
Frequently asked questions
Can I appeal a bus lane fine?
Yes. You can challenge a bus lane PCN by making a formal representation to the issuing council or, in London, to TfL. Common grounds include unclear signage, driving outside restricted hours, breakdowns, and being forced into the bus lane by other traffic.
How long do I have to appeal a bus lane fine?
You have 28 days from the date the PCN is served to make a formal representation. If you pay within 14 days, most councils offer a 50% discount. After 28 days, the fine increases and your right to make representations may be lost.
What law covers bus lane fines?
Bus lane enforcement is covered by the Traffic Management Act 2004 (outside London) and the London Local Authorities and Transport for London Act 2003 (in London). Signage must comply with the Traffic Signs Regulations and General Directions 2016.
