What does a solid white line mean?

White line pavement markings separate traffic lanes that are moving in the same direction. A single solid white line between lanes discourages lane changes, signaling that drivers should stay in their lane unless it’s necessary for safety reasons.
Solid white lines between lanes are often found near intersections, around exits, entrances, and at other spots where changing lanes could lead to dangerous situations on the road.

Solid White Line - What To Do

Remember that a solid white line means you should stay within your lane. While crossing it is not strictly prohibited, it is discouraged and should only be done to avoid a hazard. You should wait for a broken white line before attempting a lane change.
