Lowering Speed Limits

The Mayor and Transport for London (TfL) is committed to the Vision Zero Action Plan. The Action Plan sets out our ambition to eliminate death and serious injury from London’s transport network by 2041. It details our plans to reduce road danger, including proposals to implement safer lower speeds on the roads we operate and manage across London.

What are we doing?


We plan to lower the speed limit by 10mph in selected locations across London.

In early 2024, we will start works in Sutton, Hounslow, Wandsworth, Merton, Richmond, Newham and Greenwich. This will also help reduce road danger in six vital town centres where there are higher numbers of pedestrians and cyclists.


In 2023 we lowered the speed limit on roads in Camden, Islington, Hackney, Haringey and Tower Hamlets. We are currently lowering the speed limit on over 65km of our roads in Greenwich, Lewisham, Lambeth, Southwark, Wandsworth, Merton, Bromley, Ealing and Kensington and Chelsea. We aim to complete these works by the end of December 2023.


We plan to lower the speed limit using sign and line changes. Where 20mph speed limits are being proposed, we will supplement this with temporary lamp column mounted banners.


You can also view our updated maps in the 'Documents' section. Please note, these proposed changes are subject to statutory traffic order consultations.


We are committed to improving transport in London by making it safe and reliable. All of our plans have been designed with this in mind. Please view our Equalities Statement in the 'Documents' section for more information.


Why do we want to lower speeds?

Collision data from around the world is very clear. It shows the faster a vehicle is travelling the more likely a collision will occur because the driver has less time to react, stop or avoid the collision and the more severe an injury resulting from the collision will be.


If you would like to know more background information, please read our phase 1 consultation report that can be found in the Documents section.
