Dividing lines
A broken white dividing line may be crossed for a legal overtaking manoeuvre, U-turn, entry or exit when it is safe. A single continuous dividing line is more restrictive: you must not cross it to overtake or make a U-turn, although limited crossing is allowed to enter or leave a road or reach angle parking on the opposite side.
With double lines, read the line closest to your vehicle. If it is broken, the broader broken-line permissions apply. If it is continuous, do not cross to overtake or make a U-turn.
Never decide from the line on the far side. The line nearest your vehicle is the one that controls your movement.
Edge and yellow kerb lines
White edge lines mark the edge of the travelled road. Limited travel across an edge line may be allowed for specific manoeuvres, but the shoulder is not an extra driving lane.
A continuous yellow edge or kerb line means no stopping. A broken yellow line marks a clearway. Check signs as well, because signs show when the restriction operates and any permitted exceptions.
Painted islands, arrows and lane words
Painted islands separate traffic paths and protect turning space. Do not drive over an island where the surrounding lines prohibit it. Where entry into a turning lane is permitted, give way to vehicles already using that lane.
Lane arrows show permitted movements. Choose the lane before the intersection, follow the arrow and any signs, and avoid crossing a continuous lane line to correct a late choice.
- KEEP CLEAR means do not stop in the marked area
- STOP and GIVE WAY lines show the correct stopping position
- Dragon’s teeth highlight the start and end of a school zone
- Bus, transit and bicycle markings identify special-purpose lanes
A safe line-reading routine
Look well ahead, identify your intended manoeuvre, inspect every relevant line and sign, then check whether traffic conditions make the movement safe. A line may permit a manoeuvre without guaranteeing that there is a safe gap.
