Road Markings

Signs stand beside the road; markings are painted on it. They do the same job — telling you what is permitted, what is coming, and where you belong — but they work continuously rather than at a point, and they are read through the windscreen at speed rather than glanced at. This lesson covers what each line, colour and kerb marking actually means, and where the road's own geometry decides what you may do.

In this lesson you'll learn

The official shape-to-category system for road signs, completed with its third category: Rectangle = Informing
What a yellow kerb actually means, and how it differs from a yellow centre line
The precise, official breakdown of roundabout lane roles — which lane permits a full circle, and which don't

1. Reading the Lines: White, Yellow, Continuous, BrokenRead any centre or lane line by its colour and continuity, and state what each permits.
2. The Yellow Kerb, and Marked CrossingsState the four prohibitions a yellow kerb carries, and explain why surface markings can bind more comprehensively than a sign.
3. The Central Reserve: Exits and U-TurnsExplain what the central reserve is and where you are permitted to leave or reverse direction on a dual carriageway.
4. Roundabout Markings and Lane RolesIdentify the three structural parts of a roundabout and state which lane permits which movement.
