I was wondering again about cyclists waymarking routes (putting up small arrow stickers like you see for footpaths and bridleways) where councils are failing to signpost them. I found this from the Ramblers: https://www.ramblers.org.uk/advice/...nposts-waymarks-and-unauthorised-notices.aspx which points at the law https://www.legislation.gov.uk/ukpga/1980/66/section/132 against "unauthorised marks on highways" unless you have "lawful authority or reasonable excuse". Does anyone know if a longstanding failure of the highways department to waymark any cycle routes between some towns (or authorise anyone to do it) would be a "reasonable excuse" for cyclists to do it for themselves? What is considered a "reasonable excuse" under that section? Has it happened anywhere? Most of the places I suspect people would be inclined to do it, such as Bristol, I think already have councils doing it. I found no relevant case law on bailii.org but I'm not great at using it. Thanks in advance for any pointers or experiences.
