Lane markings Lane markings can be yellow or white, single or double, solid or broken. These lines provide important information about direction of traffic flow, lane changing, lane restrictions, and passing. Solid line markings: Solid lines mean that crossing the solid line to pass or change lanes is not permitted. Broken line markings: Broken lines mean that crossing the broken line to pass or change lanes is permitted. Yellow line markings: Yellow lines mean that vehicles on each side of the yellow line must travel in opposite directions. A yellow line should always be on the driver’s left side. Passing safely is permitted across single solid yellow lines within an urban area. In all other instances, single or double solid yellow lines indicate that passing is not permitted. Broken yellow lines indicate that passing is permitted. Be sure that the lane is clear and the pass can be completed safely. A solid yellow line and a broken yellow line together indicate that a pass is permitted for the driver who has the broken line on their side of the roadway. Passing is not permitted for the driver with the solid yellow line on their side of the roadway.Text extracted from the PDF for reference and may contain layout artefacts.
