About

Crossings on major roads should be located away from conflict points at uncontrolled junctions. The controlled area may extend across the mouth of a side road but it should never stop between the two projected kerb lines of the minor road. If this would otherwise occur, the zig-zag lines should be extended to the projection of the far kerb line of the side road. ii) diagram 1040.2 must be used on the approach to a staggered crossing (Schedule 4, Part I, para 3(3)). Road markings serve a very important function in conveying to road users information and requirements which might not be possible using upright signs. They have the advantage that they can often be seen when a verge-mounted sign is obscured, and, unlike such signs, they can provide a continuing message.
