<P> A yellow line ( solid or dashed ) indicates that crossing the line will place a driver in a lane where opposing traffic is coming at the driver . A double yellow line is a painted marking separating two lanes of a road . It consists of two parallel , solid yellow lines , and its presence usually indicates a no - passing restriction or no passing zone , where crossing the line is prohibited . Obvious exceptions to this no - passing restriction include emergency maneuvers or temporary traffic flow changes due to road work . Often the double yellow line has sections where one of the lines becomes dashed ( in which case it is no longer a `` double yellow '' ) , indicating to the drivers traveling on the side closest to the dashed line that they may pass when it is safe . Double - yellow lines may be used to separate lanes of traffic traveling in opposite directions where passing would be dangerous , or to restrict access to lanes traveling in the same direction , such as HOV and express lanes on a highway . </P>
