A red route is a road, mainly in UK cities, where stopping, parking, or loading is very strictly limited or completely banned to keep traffic flowing on busy main routes.

What a red route is

  • A red route is usually a major urban road marked with single or double red lines along the kerb.
  • Its main purpose is to reduce congestion and delays by preventing vehicles from stopping and blocking key traffic corridors.

Single vs double red lines

  • Single red lines mean stopping, waiting, or loading is only banned at certain times shown on nearby signs, often during busy hours.
  • Double red lines mean no stopping at any time, day or night, except for very limited exemptions such as true emergencies or designated bays.

Where you find red routes

  • Red routes are most common in London but are also used in other large UK cities and busy corridors such as near airports, hospitals, and city centres.
  • Local transport authorities use them on roads that carry heavy traffic or important bus routes so public transport and emergency vehicles are not delayed.

Why red routes matter

  • By keeping vehicles from stopping, red routes help cut traffic jams and improve journey times for general traffic and buses.
  • They also improve safety by reducing hazards from vehicles suddenly stopping or parking in live traffic lanes.
