Bus Lane Exemption (Taxi / Emergency Vehicle / Cyclist)
Summary
Bus lane PCNs fail where the vehicle that used the lane is of a class expressly permitted by the operational signs. Traffic Signs Regulations and General Directions 2016, Schedule 9, Diagram 958.1 governs bus lane signs — they must display the permitted vehicle classes. Licensed taxis, motorcycles, and cyclists are commonly permitted on many bus lanes. Emergency vehicles responding to calls are exempt under Road Traffic Regulation Act 1984, Section 87. Success rate is approximately 90% where vehicle class exemption is clearly evidenced.
Legal Basis
Traffic Signs Regulations and General Directions 2016, Schedule 9, Diagram 958.1: bus lane signs must show operational hours and permitted vehicle classes. Road Traffic Regulation Act 1984, Section 87: exemption for emergency vehicles responding to emergency calls. Traffic Management Act 2004, Part 6: civil enforcement applies only to non-exempt vehicles — a vehicle of a permitted class has not committed a contravention.
When This Defense Applies
This defense applies where: your vehicle is a licensed taxi (hackney carriage or private hire in some boroughs) and the sign shows taxis are permitted; your vehicle is a motorcycle and the sign permits motorcycles (many bus lanes in London and other cities permit motorcycles); you were cycling and the restriction applies only to motor vehicles; you were operating an emergency vehicle responding to an emergency. The key evidence is the bus lane sign itself — photograph it, including the legend showing permitted vehicle classes.
Evidence Required
The sign photograph is essential:
- Photo of the bus lane operational sign (Diagram 958.1) showing operational hours and permitted vehicle classes
- Proof of vehicle type: taxi licence, motorcycle registration document, emergency vehicle registration
- If emergency vehicle: dispatch record or incident log confirming emergency response status at the time
Win Rate
Approximately 90% success where the vehicle class exemption is clearly documented. One of the highest-success defenses because it is a complete and factual defense — if your vehicle is permitted by the sign, no contravention occurred.

Frequently Asked Questions
- What vehicle classes are typically permitted in bus lanes?
- This varies by sign — always check the specific sign at the location. Common permitted classes: licensed taxis (hackney carriages); motorcycles (in TfL and many northern city bus lanes); pedal cycles; in some cases, local bus services only. The sign must show which classes are permitted.
- I was in a taxi but the lane only shows 'TAXIS' — does that include private hire?
- The distinction between hackney carriages and private hire vehicles varies by council. 'Taxis' in TSRGD terms typically means licensed hackney carriages. Private hire vehicles (Ubers, minicabs) are not always permitted unless the sign specifically includes them. Check your local authority's position.
- The sign says 'no motorcycles' — can I still argue this?
- If the sign explicitly excludes your vehicle class, this defense does not apply. Use the sign photographs to verify exactly what is and is not permitted — do not assume motorcycles are always allowed.
- I was driving an ambulance but not on a call — am I still exempt?
- The Road Traffic Regulation Act 1984, Section 87 exemption applies to emergency vehicles 'used for fire brigade, ambulance or police purposes.' The vehicle does not need to be on an active emergency call in all circumstances, but enforcement authorities and adjudicators may require evidence of emergency purposes at the time.
