“A warning line is used to indicate that it is inappropriate to cross over it due to the traffic conditions. The marking indicates the boundary between lanes intended for travel in opposite directions. The marking may also be used to provide advance warning of a coming continuous line. The marking has the distance ratio of 3:1 between dashes and spaces.” (Traffic Sign Ordinance)
