# With-flow bus lane — UK road sign

A blue sign showing a bus and cycle, marking a lane reserved for buses running in the same direction as other traffic.

A with-flow bus lane runs alongside general traffic in the same direction. The sign is a blue rectangle showing a bus, often with a cycle and taxi symbol, plus the hours of operation.

The lane is separated by a solid white line and the words BUS LANE painted on the surface.

## What this sign means

During the hours shown the lane is reserved for buses and any other users listed on the sign, typically cycles and licensed taxis.

If no times are shown, the lane operates twenty four hours a day.

## What to do when you see it

Read the hours before deciding whether you may use the lane.

- Stay out of the lane during its hours of operation.
- You may cross it to turn left into a side road or a driveway.
- Do not park or load in the lane while it is operating.
- Check mirrors for cyclists before crossing the lane.

## How this sign is tested

Questions test who may use a bus lane and what happens when no times are displayed, which means the lane is always in force.

Others test that you may cross the lane to reach a side road.

## Common mistakes

Using an empty bus lane to pass a queue during operational hours, which is enforced by camera in most cities.

Assuming a lane with no times shown is only busy at peak periods.

## Test yourself on this one

Road and traffic signs is the biggest category in the question bank with 102 questions, and signs turn up inside other categories too. Work through them free, no sign-up needed.

## Frequently asked questions

Can I drive in a bus lane outside its hours?

Yes, you may cross it to enter or leave a side road or premises.

## Passed your theory? Get the practical booked

Your theory certificate lasts two years. Most learners who use it quickly do it with an intensive course — a block of hours with a DVSA approved instructor and a practical test at the end, instead of one lesson a week for months.
