TfL to launch 65km of new lower speed limit schemes to cut road danger across the capital and save lives

11 September 2023

20mph speed limits will be introduced across 65km of roads within the Royal Borough of Greenwich, the Royal Borough of Kensington and Chelsea, Lewisham, Southwark, Wandsworth, Merton, Bromley and Lambeth

Transport for London (TfL) will introduce 65km of new 20mph speed limits within the Royal Borough of Greenwich, the Royal Borough of Kensington and Chelsea, Lewisham, Southwark, Wandsworth, Merton, Bromley and Lambeth. The new speed limits will be introduced in stages over the last four months of the year, making London's streets safer for everyone. Each year in London, more than 1000 people are injured or killed by drivers exceeding the speed limit and lowering speed limits is a key part of the Mayor's Vision Zero goal to eliminate death and serious injury from London's transport network and to enable more walking and cycling in the capital. The plan to introduce new speed limits comes as TfL today launches a powerful new road safety campaign to tackle speeding.

The new speed limits will help make a large area of south London safer and more attractive for people in these communities to live and work in, encouraging people out of their cars to walk, cycle and use public transport more often. Enabling more people to use healthier and more sustainable forms of travel will be vital to reducing congestion and air pollution. Once the works on the new speed limits are finalised, TfL will have delivered 140km of 20mph roads, ahead of its target to do this by May 2024.

The speed limits will be supported by new signs and road markings and TfL is working closely with the Metropolitan Police Service to ensure that drivers understand and comply with the new lower speed limits. Banners attached to street lamps in the new 20mph areas will also be put in place to increase driver awareness of the new speed limit. Following implementation, TfL plans to carry out monitoring to determine whether further measures to further reduce vehicle speeds are required.

Data collected from 1 May 2020 to 30 June 2022, when compared to a similar seasonally matched period before lower speed limits were implemented, shows the number of collisions fell 25 per cent (from 405 to 304), and collisions resulting in death or serious injury fell 24 per cent (from 94 to 71). The reduction in collisions resulting in death or serious injury on roads within the central London Congestion Charging Zone should be seen in the context of a London-wide reduction in collisions resulting in death or serious injury of around 10 per cent over the same period. This demonstrates that reducing speeds leads to greater benefits than on roads where speeds have not been reduced.

Collision data from around the world shows that the speed at which people are driving or riding is the single most important factor in whether a collision takes place and how severely people are injured. Around half of the 2022 fatal collisions in London (48 out of 99) reported speed as a contributory factor. The devastating consequences for the families, friends and communities impacted by these casualties is immense, and TfL has launched a new powerful road safety campaign to tackle speeding.

The campaign aims to challenge these socially accepted driving norms by reframing drivers' perception of what counts as speeding, particularly in lower speed limit roads (20/30 mph). It aims to motivate all drivers to change their behaviours by showing them that driving even slightly over the speed limit can still have devastating consequences, particularly on those who walk, cycle and ride a motorcycle and who are the most likely to be impacted by a speed related collision. The campaign launches on radio and outdoor posters, with a new TV advert launching in October in the lead up to Road Safety Week (19-25 Nov), where this year's theme is speed.

TfL is also working with the Met Police to increase their capacity to take enforcement action against drivers and riders who speed. They are currently on track to be able to take action on a million speeding offences by 2024/5, to provide a more effective deterrent to speeding. The Met Police enforced around 620,000 speeding offences committed in 2022/23, an increase of 35 per cent compared to the previous year.

Walking and Cycling Commissioner, Will Norman, said: "Lowering speeds is one of the most important things we can do to reduce road danger and forms a key part of the Mayor's Vision Zero goal to eliminate death and serious injury from London's transport network. TfL data shows that 20mph speed limits are reducing the number of collisions on London's roads, which is why I'm pleased the 20mph programme has been expanded, helping to make a large area of south London safer and more attractive for people to live and work. Every death or serious injury on our streets is devastating, bringing heartache and tragedy to all those involved so we will continue to work with TfL, the Met Police and London's boroughs to make it easier and safer for people to walk, cycle and use public transport, creating a safer, greener London for everyone."

Lilli Matson, TfL's Chief Safety, Health and Environment Officer said: "We are determined to eliminate deaths and serious injuries from London's roads in line with our Vision Zero goal. Speed continues to be a factor in almost half of fatal collisions in London and the devastating consequences for the families, friends and communities impacted by these casualties is immense. We're committed to eliminating unsafe speeds across London and our new campaign aims to challenge drivers' perception of what counts as speeding, as even driving slightly over the speed limit can still has tragic consequences. These new 20mph speed limits will also not only save lives, but make it easier and safer for people to walk, cycle and use public transport, creating a safer, greener London for everyone."
