Luke Hanson highlighted that one of my old posts referenced a Department for Transport webpage that doesn’t exist anymore. As an alternative he proposed an alternative like for a group that he volunteers with, the Road Safety Group. Part of his role is to research road safety resources to share with our stakeholders, this led me on to your website and is how I found the broken link.
If you are looking for a replacement then I?d like to highlight this alternative link which has a lot of useful information as well as some specific guidance for London cyclists.
