My hon. Friend makes an important point. He is right: the purpose of such road hatching is to segregate traffic, discourage overtaking, encourage driver discipline and provide crossing opportunities for pedestrians. However, as he said, it can also lead to vehicles being closer to pedestrians. Great care is required when planning such measures. It is the responsibility of the highway authority concerned. The Department issues guidance, and we shall review that guidance during the coming year. I shall ensure that my hon. Friend's points are taken on board.
