Your route was outside Bristol's clean air zone
Bristol's clean air zone only covers a specific area — it does not include every part of central Bristol. Cameras on the roads that run along the edge of the zone sometimes capture vehicles that were travelling on those boundary roads but never actually entered the zone itself. If that happened to you, the charge should not have been issued.
Legal basis
