Road Markings and Traffic Signals
Core concepts
Horizontal markings (lines, arrows, hatchings, stop lines, zebra crossings) and vertical markings (on barriers, posts, kerbs) work together with signals. Learn the meaning of solid versus broken lines: a solid line generally cannot be crossed, a broken line may be crossed when safe, and a double line (one solid, one broken) means the side with the solid line may not cross. Lane arrows indicate permitted directions; a hatched area bordered by solid lines is not to be entered.
Traffic signals
Know the standard three-colour sequence, the meaning of a flashing amber (proceed with caution, yielding to pedestrians where applicable), and the rule that a green light does not guarantee a safe path. Signals from a traffic controller override light signals, and light signals override signs of priority. Pedestrian signals and combined signals must be interpreted with the crossing rules.
Traps in questions
- A green light means you may proceed if the way is clear; a blocked junction must not be entered even on green.
- A flashing amber is not the same as a steady amber (which means stop unless stopping is unsafe).
- A yellow box or hatched area is not a parking space.
- A controller's signal outranks a traffic light, which outranks a priority sign.
Rule of thumb
Apply the hierarchy: controller > traffic light > priority sign > general priority rule. If the light is green but the exit is blocked, treat it as red and wait before the stop line.
