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

In some cases pavement markings are used along with other traffic control signs or signals.
