Chapter 5: Pavement Markings
Yellow lines separate travel lanes moving in opposite directions. White lines separate travel lanes moving in the same direction. A yellow
skipped or broken line is used as the center line on a two-lane, two-way road where passing with care is permitted in both directions.
When continuous, double, solid, yellow lines are the center lines you cannot cross them to pass in either direction. On a two-lane road,
passing with care is permitted if the skipped yellow line is in your lane.
Single, solid, white lines are used as right-edge lines along the roadway and for guiding traffic traveling in the same direction. Single,
solid, yellow lines are used as left-edge lines on divided highways. If you see the reverse, you are traveling in the wrong direction.
On certain multi-lane highways, a special center lane is reserved exclusively for two-way left turn movements in both directions. The two-way
left turn lane must not be used for passing or overtaking another vehicle. The marking for this type of lane is shown by the diagram below.

White and yellow pavement "markers" are reflective devices used in the pavement to improve the visibility of marking lines at night when
the road is wet. Red markers indicate wrong-way movements for motorists.
