You asked

What evidence do you have that Advanced Stop Lines are widely understood by all motorists? Are discussions about the cycle boxes taking place between TFL and MPS? Is anyone at TFL specifically responsible for cycling issues?

We answered

TfL Ref: FOI-4557-2324

Thank you for your request received by Transport for London (TfL) on 8 March 2024 asking for information about Advanced Stop Lines (ASLs) at junctions.

Your request has been considered in accordance with the requirements of the Freedom of Information Act and our information access policy. I can confirm that we hold the information you require.
The requirement for motor vehicles to stop at behind the first ASL is made clear within the Highway Code (rule 178). It is therefore expected that drivers in London should understand the purpose of ASLs and the requirements of motor vehicles when they are encountered. Enforcement of ASLs lies solely with the Metropolitan Police Service (MPS) as the contravention of ASLs are covered by the same section of the Road Traffic Act as that pertaining to the contravention of a red traffic light.

Our Vision Zero approach includes liaison with the MPS on the role of enforcement for road safety, with a particular focus on the most vulnerable road users, being those who walk and cycle. More information is available on our website here:

Our overall approach to cycling is set out within our Cycling Action Plan available here: , led by the Mayor’s Walking and Cycling Commissioner, Will Norman.

Please see the attached information sheet for details of your right to appeal.

Yours sincerely,

Mary Abidakun
