Controlled parking zones (CPZs) are areas where all on-street parking is controlled. This helps keep roads free from dangerous parking and give priority to residents and local businesses, who must display a parking permit or voucher.
Designated parking bays are shown by white road markings and the remainder of the kerbside is subject to parking restrictions.
There are signs at the entry roads to all CPZs stating the hours during which the controls and yellow line restrictions are operational. Visitors parking in the bays during these hours must use the pay and display machines as the controlled parking zones are monitored by traffic wardens.
