20mph speed limit

Traditional traffic calming measures such as speed bumps have often proved unpopular, so we have made our roads safer by introducing a 20mph speed limit in residential areas.

We want all of our residents and particularly children and young people to be able to walk, cycle and play safely on our streets.

A 20mph speed limit improves road safety throughout the borough, saves lives and prevents serious injuries. A pedestrian, if struck by a vehicle at 20mph, is likely to suffer slight injuries. At 30mph they would be severely hurt and at 40mph or above are likely to be killed. 

Changing driver behaviour

We want to change driver’s attitudes and behaviours when travelling on residential streets rather than prosecute speeding offences. However, the 20mph speed limit is legally enforceable by Greater Manchester Police (GMP).

If you are concerned about vehicle speeds in your area, as part of The Deal we are giving residents the opportunity to record the speed of vehicles travelling through their neighbourhood. 

Classified roads

We do not install speed bumps on classified roads. This is because we have a Network Management Duty, which requires local traffic authorities to do all that is reasonably practical to manage the network effectively to keep traffic moving.

Due to the type of vehicles using classified roads, such as buses and heavy goods vehicles, vertical traffic calming measures like speed bumps may generate additional noise and vibrations to the annoyance of nearby residents. This may lead to an increase in complaints.    

Road signs

Road signs alert drivers when entering a 20mph area and are placed at junctions where the speed limit changes.

Speed bumps will not be constructed as part of the 20mph speed limit on residential roads plan. Where the speed limit is lowered to 20mph it will be controlled by signs only. There are no plans to remove any existing speed bumps.
