The borough has a 20mph speed limit across all council-owned residential roads
A South London council is cracking down on drivers exceeding the 20mph speed limit on residential roads. Kingston Council will install speed indicators across 18 roads in the borough to encourage drivers to stick to the speed limit and improve safety.
The council has been reviewing drivers’ speeds across Kingston to assess compliance with the 20mph speed limit it rolled out across all residential roads it controls in the borough. A survey of 40 roads showed that while the average speed had fallen across all of them since the rollout, only 22.5 per cent of the roads had an average speed that did not exceed 20mph. The roads were chosen as they had previously recorded high speeds.
The results showed 65 per cent of the roads recorded an average speed between 20mph and 24mph. The council will install extra speed indicators on these roads to remind drivers to watch their speed. The devices will monitor speed and provide feedback to the council.
A new report by council officers said the authority aims to improve road safety, make streets more welcoming for pedestrians and cut vehicle emissions by requiring drivers to stick to the 20mph speed limit.
Data provided by Transport for London (TfL) showed the number of collisions in Kingston has fallen by roughly 18 per cent since the introduction of the 20mph borough-wide speed limit. There were 1,039 collisions, including four fatalities, between 2017 and 2019. This compares to 883 collisions between 2022 and 2024, which resulted in four deaths.
The council has confirmed the roads in the borough where new speed indicators will be installed, which are listed below:
- Coombe Lane West
- Kingston Road (near Kingsmeadow)
- Blakes Avenue
