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 in central London.

In the next phase of the lowering speed limits programme we will introduce safer speeds on a further 25km by March 22. Once the work is complete and safer speeds are in operation, we will be asking for your views and experiences on the new lower speeds.

Why do you 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.

We have reduced speed limits in the Congestion Charging Zone to 20mph and recently consulted on plans to do the same on all our roads in Westminster. We are now taking action across the rest of the Transport for London Road Network (TLRN). As of August 2021, we have provided a 20mph speed limit on over 80km of the TLRN across London. If you would like to know more background information, please read our consultation report that can be found in the Documents section.

What's next?

We are progressing plans to lower the speed limit by 10mph in locations across London and will begin works later this year to schemes in Enfield, Haringey, Hackney, Tower Hamlets and Croydon. By March 2022, we also plan to reduce the speed limit on Gants Hill roundabout, Redbridge, Ruislip Road, Ealing and Upper Richmond Road, Wandsworth. See the 'Key dates' section for timelines. You can also view our detailed maps in the 'Documents' section. Please note, these proposed changes are subject to statutory traffic order consultations.

By March 2024, we aim to lower the speed limit on a further 140km of TLRN, including 37 town centre locations to provide safer, more pleasant environments for people to travel within London. We will continue to update this page with new schemes as we plan them. You can view a schedule in the Documents section.
