*White markers &mdash; for [[lane|lane marking]]s or to mark the right pavement edge.
*Yellow or orange markers &mdash;  These separate traffic moving in opposite directions, or mark the left pavement edge on one-way roadways.
*Blue markers &mdash; Usually placed near the center of the roadway, offset to one side to mark the location of [[fire hydrant]]s on the shoulder or at the curb.
*Green markers &mdash; Usually used to indicate that [[emergency vehicle]]s can open gates to enter a [[gated community]].
*Red markers &mdash; Usually indicate areas that are closed to traffic.

Colors can also be combined, with a different color facing each direction:
*White and red or yellow and red &mdash; white or yellow for normal use in one direction, and red to indicate "do not enter" or "wrong way" in the other direction. Red-Clear Markers are primarily used to warn motorists they are going the wrong way; most people have never seen these because they show clear when approached in the correct direction, and only appear red to wrong-way drivers.<ref>California Department of Transportation (Caltrans) Standard Plan A20A & A20C</ref>
*White and black &mdash; white for marking lane restrictions (such as an [[High-occupancy vehicle lane|HOV]] diamond) in one direction on a roadway that has "reversible" traffic flow, and black in the other direction when the markings do not apply.

The current trend for lane markings is to intersperse [[Retroreflector|retroreflective]] paint lines with reflectors as seen on the majority of American highways.

This scheme only applies to the US and Canada. Mexico, on the other hand, generally follows European usage.
