Road marking
School keep clear markings
What do school keep clear markings mean?
Keep this stretch outside a school clear. Do not stop, not even to drop off or pick up children.
Also known as: Yellow zig-zag lines
What it means
You should not stop on the markings, not even briefly. Where there is an upright sign, stopping is banned during the times shown.
The yellow zig-zags keep the road outside the school entrance clear, so children can see and be seen when crossing.
Similar yellow zig-zags are used outside hospitals and fire, police and ambulance stations.
Where you'll see it
Outside school entrances, and similar markings outside hospitals and emergency service stations.
Rules to know
You must not wait or park, or stop to set down and pick up passengers, on school entrance markings when upright signs indicate a prohibition of stopping.
The Highway Code, Rule 238
