Center Line (Separation Line)
Lane Line
Barrier Line
Edge Line
Transition Line
This is used to separate opposite traffic movements of an undivided roadway and is generally placed centrally on all roads and bridges 6.0m or more in width.
Center Line
This is used to separate adjacent lanes of traffic moving in the same direction. They are generally broken lines except where lane changing is to be discouraged (but not prohibited) particularly on approaches to intersections.
Lane Line
Barrier lines may consist of either:
Double unbroken yellow lines
Single unbroken yellow line
Single yellow line with a broken line
These should only be used where overtaking from both directions of the road and all crossing movements are prohibited. Vehicles must always keep to the right of these.
Double unbroken yellow lines
These should be used where overtaking from both directions of the road are
prohibited. However, crossing movements are permitted.
Single unbroken yellow line
passing is permitted on the side of the broken line but not on side of solid line
Single yellow line with a broken
line
This is used to delineate the edge of the
traveled way to distinguish it from the
shoulder area. It should be a solid white line between 100mm and 200mm wide.
Edge Line
Edge lines at raised medians are _______ wide and placed with the center of the line
not more than _______ from edge of the
median curbing.
100 mm
