Red routes in the UK: what the red lines mean and what you can't do
Red routes carry more traffic than any other road type, and the rules about stopping are deliberately stricter. Here's what drivers need to know.
What is a red route?
A red route is a road designated as a priority route for traffic flow, marked with red lines along the kerb instead of yellow. They are most common in London, where Transport for London (TfL) manages around 580km of red routes — covering about 5% of London's roads but carrying around 33% of its traffic.
Double red lines: no stopping at any time
Double red lines mean you cannot stop, park, load, or unload at any time. Unlike double yellow lines, there is no concession for Blue Badge holders on double red routes. The only exception is a licensed taxi setting down or picking up a passenger who has booked in advance.
Single red lines: time-restricted
A single red line means stopping is prohibited during the times shown on the adjacent red-backed time plate (e.g. 'No stopping Mon–Sat 7am–7pm'). Outside these times, you can normally stop to load, unload, or drop off — but parking is still not allowed unless a bay is marked.
Red route clearways
Some red routes are also clearways — indicated by a blue circular sign with a red X. On a clearway, stopping is prohibited at all times, even for taxis and emergency loading. Clearways are used at junctions and bus stops where any stopped vehicle creates an immediate hazard.
Fines on red routes
Stopping on a red route can result in a PCN from a council Civil Enforcement Officer or from a TfL camera. Fines are typically higher than standard parking penalties — up to £160 in London, reduced to £80 if paid within 14 days.
