A 'KEEP CLEAR' road marking consists of white or yellow lettering painted directly onto the carriageway, sometimes enclosed within a box outline.
It is placed at junctions, fire stations, ambulance bays, and side-road entrances to stop traffic queues from blocking emergency and turning access.
What this sign means
This marking indicates that the designated area must be left clear of stationary traffic.
It ensures vehicles emerging from side roads, emergency depots, or facilities are not blocked by stationary main-road queues.
- Clearway function: Protects access to side streets and emergency services.
- Queuing rule: You must not stop in the marked area when traffic slows or stops.
What to do when you see it
Scan traffic ahead. If vehicles are queued beyond the 'KEEP CLEAR' area, hold back behind the text until space opens on the far side.
Only drive across the marking if you are certain your vehicle can clear the entire painted boundary without stopping.
How this sign is tested
Theory tests check whether you understand how to manage queueing traffic at junctions marked with 'KEEP CLEAR'.
During practical driving tests, blocking a 'KEEP CLEAR' section while queueing results in a driver fault.
Common mistakes
Inattentive queueing that leaves a vehicle stopped right on top of the 'KEEP CLEAR' lettering.
Assuming 'KEEP CLEAR' markings apply only to emergency vehicles, when they protect side-junction access for all road users.
