Controlled parking zones
Controlled Parking Zones (CPZs) are roads or sets of roads where the parking places and single yellow lines which form the CPZ are controlled for a certain period during the day, with the aim (for the most part) of prioritising local parking.
The operational times of a CPZ will be indicated on the entry boards, which are positioned to face traffic coming into the area. If a yellow line operates at different times to the CPZ it will be individually signed.
