Parking management regulations
Parking management schemes can be introduced using a mixture of the following kerb-space management regulations.
Double yellow lines (DYLs)
DYLs are installed only where it is inappropriate for vehicles to be left at any time day or night. This is typically at the corners of junctions or on bends where visibility is poor, the manoeuvrability of larger vehicles is restricted and/or a way through is not possible because of inappropriately parked vehicles. Access for emergency service, waste collection and delivery vehicles is sometimes a problem and DYLs can help to ensure a way through is clear.
Single yellow lines (SYLs)
SYLs are installed where streets are too narrow to accommodate vehicles parking on both sides of the road. Existing examples are observed where cars are left with at least two wheels on the footway, which usually leaves the carriageway clear for vehicles; however, this parking practice prevents pedestrians travelling freely on the footway. Footway parking is especially problematic for pedestrians with young children in push-chairs and disabled persons including those with no or partial sight and wheel-chair or mobility scooter users. SYL timings vary and drivers should always check the signs to see when the yellow line is in operation. Typically, SYLs prevent all day parking by non-residents, but provide parking options for on-street parking at other times including overnight by residents and their visitors with consideration to other highway users.
Limited waiting bays
Waiting bays allow drivers to park their cars free of charge in accordance with the times detailed on the signs. Operation times can vary as can the duration of stay and these are installed predominantly for visitors to residents and local businesses.
Permit parking bays (PPBs)
PPBs prioritise on-street car parking most commonly for residents (without driveways) and their visitors. PPBs may be used by Resident Permit holders, Visitor Permit holders and trades people with a Dispensation Certificate. There are different Zone Codes and so residents must ensure the bay parked in matches the Zone Code on their permit. Permit scheme operation times vary and residents may not need a permit if their cars are not left on-street during these times, for example, the cars are driven to work.
