What does a solid white line on the road indicate?

A solid white line on the road indicates that lane changes are discouraged. It serves as a boundary that drivers should not cross unless necessary. This line typically appears on multi-lane roads, and it helps maintain a smooth flow of traffic by clearly defining lanes.

When you see a solid white line, it's a signal to stay within your lane for safety reasons. This is particularly important in areas where lane changes could create hazards, such as near intersections, in construction zones, or where there is heavy traffic. Understanding these regulations helps ensure safer driving practices and reduced accidents on the road.
