United Kingdom
1. Zone
A traffic zone is an area in which a traffic rule applies throughout all included roads or road sections. The rule normally begins at a zone-entry sign and remains applicable until the corresponding end-of-zone sign is passed.
Zones may regulate speed, parking, access, vehicle categories, emissions or other traffic behaviour. The signs used, the roads covered and the effect of intersections or local exceptions depend on local traffic law.
How do people refer to traffic zones in the United Kingdom?
Examples include a 20 mph zone and a controlled parking zone. These impose different rules. A speed-zone entrance must not be confused with an entrance displaying waiting restrictions or parking conditions.

Where does a zone rule apply in the United Kingdom?
A 20 mph zone’s limit applies within its designated area, with entrance and exit signing. A controlled parking zone principally conveys the waiting restrictions and operating times for its yellow lines; individual parking bays may have separate conditions.

Does a UK controlled parking zone mean every parking bay has the same hours?
No. Read the signs for the individual parking bay. The zone-entry times normally govern the zone’s yellow-line waiting restrictions, while bays and separately signed restrictions can have different conditions.

How do you know when a traffic zone ends in the United Kingdom?
Look for the relevant zone-end sign or a change to the applicable speed or parking arrangement. Leaving a parking zone does not remove a speed limit, and leaving a speed zone does not cancel parking restrictions.
