About this bus lane
The A4 bus lane scheme has been one of Slough's most controversial — check the council page for its current status before relying on it.
The Borough of Slough (A4) Experimental Bus Lane Order 58 of 2020 (made permanent by Cabinet decision 17 January 2022, in force from 25 February 2022) sets the full exemption list: buses, pedal cycles, solo motorcycles (not motorcycles with a sidecar), taxis, SBC-licensed private hire vehicles displaying the council's identification marks, and vehicles lawfully displaying a green number plate (zero tailpipe emissions).
Operates Monday to Friday, 7am to 10am and 3pm to 7pm; outside those hours general traffic may use it. Transcribed from the sealed Order and corroborated by Slough Borough Council's Parking Enforcement Policy (August 2025), which lists every enforced bus lane and bus gate in the borough and sets the penalty for being in a bus lane at £70, reduced to £35.

Frequently asked questions

Who is allowed to use the Bath Road (A4) bus lane?

Can I appeal a PCN from the Bath Road (A4) bus lane?
Yes, and it costs nothing. Make formal representations to Slough Borough Council first — the authority that issued the PCN has to consider them before it can enforce the penalty. If Slough Borough Council rejects them it must issue a Notice of Rejection, and you can then appeal free to the Traffic Penalty Tribunal. Its adjudicators are lawyers independent of the enforcing authority, and their decision is binding on both sides. The grounds that win here are that your vehicle was not in the bus lane during its operating times (Mon–Fri 7–10am & 3–7pm), that it was an exempt vehicle, or that the signage did not make the restriction clear. It is worth doing: Slough Borough Council accepted 41% of the 2,192 formal challenges it received in 2025/26, and of the 80 that went on to the tribunal, 6 succeeded (figures from its own FOI response). Note that paying the £35 discounted rate accepts liability and closes the case, so challenge before you pay.
