Buckinghamshire Bus Lane Fines — High Wycombe & Aylesbury

Castle Street doubled in its first full year, from 5,233 penalties over ten months in 2023/24 to 10,775 in 2024/25, then fell by a third to 7,146 in 2025/26 — the shape of drivers gradually learning a bus gate rather than of any change to the restriction. Oxford Road's arrival in May 2025 partly offset that fall, adding 1,305 penalties in its first eleven months and taking the county to 8,451. Income follows the same curve, peaking at £261,543 in 2024/25 and falling to £173,905. One figure stands apart from other authorities: only about 40% of these penalties were paid at the £35 discounted rate — 3,359 of 8,451 in 2025/26, and 1,834 of 5,233 in 2023/24 — where councils that publish the same breakdown typically report two thirds or more. The council did not comment on why.

Which cameras issue the most fines

Camera-enforced bus lane locations ranked by PCNs issued in 2025/26. The last column is the 3-year total.

Buckinghamshire camera-enforces only two bus lanes, and they sit 20 miles apart. Castle Street in High Wycombe is a bus gate open to buses alone — not even taxis are exempt — and it has issued all but 1,305 of the county's bus lane penalties. Oxford Road in Aylesbury is a 24-hour bus lane that also admits cycles, motorcycles and black cabs; the council described it as live, yet it issued nothing at all until May 2025. A third site, the A40 London Road bus lane in High Wycombe, has a camera that the council confirmed in August 2026 is not yet operational, so no penalty is being issued there for now — the lane itself is live and signed, and the camera can be switched on at any time. A fourth location the council enforces on Corporation Street in High Wycombe is deliberately absent from these figures: the council classes it as a vehicle prohibition rather than a bus lane or bus gate, so its penalties are not bus lane penalties.
