LONGITUDINAL LINES
LONGITUDINAL LINES delineate vehicular paths of travel along the roadway by marking the center of the road, lanes of travel, edges of pavement, etc. The COLOR of a longitudinal line tells drivers whether they are on a one-way road or whether there may be opposing traffic to the left of the line. The PATTERN and/or WIDTH of a longitudinal line tell drivers whether it is permissible, discouraged, or prohibited to cross the line.
There are three main types of longitudinal lines. Click on each to learn more, starting with Centerlines.
