Lane Line Types and Meanings

Yellow Lane Lines: Separate traffic moving in opposite directions; single lines may indicate the left edge on divided highways and one-way streets.
Broken Yellow Line: Indicates that lanes of traffic move in opposite directions; crossing permitted temporarily when safely passing another vehicle.
Double Yellow Lines: Solid lines prohibit crossing for vehicles traveling in either direction; permissible only when turning left and safe to do so.
Double Yellow Lines: One Solid, One Broken: A solid line next to a broken line restricts passing from the solid side; passing allowed from the broken side when safe.
White Lane Lines: Separate lanes moving in the same direction; single white lines can also indicate the right edge of the roadway.
Broken White Line: Indicates lanes traveling in the same direction; crossing allowed when signaling and safe to change lanes.
Solid White Line: Marks the right edge of the roadway or separates same-direction lanes; crossing allowed only to avoid hazards.
Double Solid White Line: Prohibits crossing; used to maintain separation between same-direction lanes.
Solid with Turn Lane Arrow: Designates turn lanes and discourages lane changes near intersections; arrows indicate permissible turns from this lane.
Reversible Lanes: Used to manage rush-hour traffic; direction reverses at designated times, marked with special signals and signs.
Two-Way Roadway with Center Lane: Allows drivers from both directions to use the center lane for left turns; lane intended for slowing down, not for passing.
