What Do Road Markings Mean?

Road markings are painted lines and symbols on roads that guide drivers, organize traffic flow, and show where it is safe or unsafe to overtake. They are an essential part of traffic safety infrastructure.

Short answer

Road markings are white or yellow painted lines that divide lanes, indicate no-passing zones, mark stopping points, and guide traffic direction. White lines separate same-direction traffic; yellow lines separate opposite directions.

White Lines (same direction)
  • Solid white: do not change lanes
  • Dashed white: safe to change lanes
  • Double white: never cross
Yellow Lines (opposite direction)
  • Solid yellow: no passing from your side
  • Dashed yellow: safe to pass if clear
  • Double yellow: no passing either side
