Controlled Parking Zone

A Controlled Parking Zone or CPZ is a specific type of parking restriction used in the United Kingdom that may be applied to a group of roads within the zone. The intended purpose of a CPZ is to reduce the clutter that can arise from erecting several signs that would otherwise convey the same information, such as a common time restriction sign adjacent to all the single yellow lines in the zone. A sign indicating the start of a CPZ typically states that there are parking, loading, weight or other restrictions between certain hours of operation.

The CPZ applies to all parking within the zone unless individual parking bays are signed with different restrictions.
