Has my hon. Friend noticed the increase in diagonal hatch marks, the original purpose of which was to improve lane discipline? Has he also noticed that, on certain stretches, the part of the road that has a diagonal hatch mark is considerably wider than the part that has no mark? The motorist sometimes has to drive down a stretch of road that is narrower than is reasonable for a motor car. Will my hon. Friend try to ensure that the use of such excess road markings is curbed?
