Markings on the roadway can provide the following information:
- lane identification separating opposing traffic
- traffic movement in the same direction
- traffic movement in the opposite direction
- passing zones and no passing zones
- lane use and designation
- pedestrian crosswalks
- stop lines
- parking areas
- word or symbol messages
In some cases pavement markings are used along with other traffic control signs or signals.
Lane markings can be yellow or white, single or double, solid or broken. These lines provide important information about direction of traffic flow, lane changing, lane restrictions and passing.
Solid line markings
Solid lines mean that crossing the solid line to pass or change lanes is not permitted.
Broken line markings
Broken lines mean that crossing the broken line to pass or change lanes is permitted.
Yellow line markings
Yellow lines mean that vehicles on each side of the yellow line must travel in opposite directions. A yellow line should always be on the driver's left side.
White line markings
White lines mean that vehicles on each side of the white line are travelling in the same direction.
Symbols may be used on the pavement to supplement standard signs or by themselves to warn drivers, or to regulate or guide traffic. These markings include:
Arrows indicate the vehicle movements permitted in a lane.
Diamond markings indicate that a lane is reserved for specific vehicles. There may also be signs that will indicate time or vehicle restrictions.
