In each CPZ a series of streets are grouped together in a zone. Each zone is given a unique number and expires at a different time of the year:
All owners and occupiers of premises within the zone are allowed to apply for permits. Holders of a permit for one zone (such as W1) cannot use that permit to park in any other zone (such as W2) in the borough.
If a vehicle is parked without a permit or the driver breaks any other of the rules, they will become liable for a Penalty Charge Notice.
If you are unsure about whether you are infringing the parking restrictions in the borough, always check for signs and road markings. The parking signs used in the Wigan Borough can be found in the Highway Code (external link).
A more comprehensive guide to the signs can be found in the 'Know your Traffic Signs' booklet (external link). Both booklets are published by the Department for Transport (external link).
