DPE is becoming increasingly common as more authorities take on this role. The local traffic authority assumes responsibility for enforcing many parking contraventions in place of the police. Further details on DPE may be found at the following websites:
Cars, goods vehicles not exceeding 2500 kg laden weight, invalid carriages, motorcycles and pedal cycles may be parked without lights on a road (or lay-by) with a speed limit of 30 mph (48 km/h) or less if they are:
at least 10 metres (32 feet) away from any junction, close to the kerb and facing in the direction of the traffic flow
in a recognised parking place or lay-by.
Other vehicles and trailers, and all vehicles with projecting loads, MUST NOT be left on a road at night without lights.
Loading and unloading. Do not load or unload where there are yellow markings on the kerb and upright signs advise restrictions are in place (see ‘Road markings’). This may be permitted where parking is otherwise restricted. On red routes, specially marked and signed bays indicate where and when loading and unloading is permitted.
Goods vehicles. Vehicles with a maximum laden weight of over 7.5 tonnes (including any trailer) MUST NOT be parked on a verge, pavement or any land situated between carriageways, without police permission. The only exception is when parking is essential for loading and unloading, in which case the vehicle MUST NOT be left unattended.
Controlled Parking Zones. The zone entry signs indicate the times when the waiting restrictions within the zone are in force. Parking may be allowed in some places at other times. Otherwise parking will be within separately signed and marked bays.
You MUST NOT park partially or wholly on the pavement in London, and should not do so elsewhere unless signs permit it. Parking on the pavement can obstruct and seriously inconvenience pedestrians, people in wheelchairs or with visual impairments and people with prams or pushchairs.
