I have received a penalty notice for turning left at a junction when there is a "no left turn" sign post at the junction, and a "must turn left" sign post about 30 metres further back on the road. In the past it was OK to turn left, but I guess at some point in the last year, usage had changed. My question is in two parts: - Is there any legal requirement to have a painted "turn right" sign on the road itself, in addition to sign posts? - What is the legal requirement for lighting the signs? - the junction is in a commercial area with street lights, ..because I simply did not notice the sign posts in the dark!
