Red Route Rules: Can You Stop on a Red Line?

What a red route is

A red route is a major road where keeping traffic moving matters more than kerbside parking. Instead of yellow lines, the kerb is marked with red lines, and the restriction is about stopping, not merely waiting. That is the key difference from yellow lines: on a red route you are often not allowed to stop even for a moment.

Red routes are mostly a London thing, managed by Transport for London on the busiest roads. They are always signed clearly with red-route signs as well as the red lines.

Single red vs double red lines

Double red line — no stopping at any time, day or night. No parking, no loading, no dropping off.
Single red line — no stopping during the hours shown on the nearby sign. Outside those hours, stopping is allowed unless something else restricts it.

As with yellow lines, the line tells you the type of restriction and the sign tells you the hours. The difference is that the baseline behaviour being controlled is stopping, which is far broader than parking.

Marked bays and boxes

Red routes carve out exceptions using marked bays and boxes set back from the red line. A white bay usually allows parking or loading for set users at set times; a red bay is more restrictive. Each has its own sign stating who can stop, what for, and when — for example "Loading only, Mon–Sat 10:00am–4:00pm" or a permit-holder bay. If you are not stopping inside a marked bay during its permitted hours, assume you cannot stop.

Blue Badge holders

The general Blue Badge concession for yellow lines does not apply on red routes. Blue Badge holders can only stop where a red route provides a designated disabled bay, and must follow that bay's signed conditions. Always look for the specific bay rather than relying on the badge.

Why red-route tickets sting

Red routes are enforced heavily, often by camera, and the penalty charges are typically higher than ordinary council PCNs. Because the rule is "no stopping", there is little room to argue you were only there briefly. The safe approach on any red line is to keep moving until you reach a marked bay or leave the route.

Read the bay sign before you stop

Red-route bay signs pack a lot into a small board — who, what, and which hours. Kerbnow reads the sign and checks it against the current time, so you know whether that bay is open to you right now before you pull in.

Frequently asked questions

What is the difference between a red line and a yellow line?

Yellow lines restrict waiting (parking). Red lines restrict stopping altogether — you may not even pause. Red routes are therefore stricter: on a double red line you cannot stop to wait, load or drop off at all, except where a marked bay or box allows it.

Can you stop on a single red line?

Only outside the hours shown on the nearby sign. A single red line bans stopping during the times on the time plate; outside those hours, stopping is allowed unless another restriction applies. A double red line bans stopping at any time.

Can you stop on a red route to drop someone off?

Not on a double red line, and not on a single red during its controlled hours — setting down passengers still counts as stopping on a red route. The exception is a marked red-route bay or box that specifically permits it at that time. Blue Badge holders may use designated red-route disabled bays.

Where are red routes in the UK?

Mostly London, on major roads managed by Transport for London (around 5% of London roads carry about a third of its traffic). A few other cities have used red routes too. They are always marked with red lines and red-route signs rather than yellow.
