What does a solid white line indicate regarding lane changes?

A solid white line indicates that lane changes are prohibited in areas where this line is present. The purpose of this marking is to maintain traffic safety by signaling to drivers that crossing into another lane is not allowed due to various reasons, such as the presence of pedestrian lanes, roadwork, or other safety considerations.

When drivers observe a solid white line, they should remain in their lane and avoid crossing it unless absolutely necessary for safety reasons, like in the case of an emergency. This enforcement helps preserve the flow of traffic and minimizes the risk of collisions, particularly in areas where lane changes could disrupt the movement of vehicles or endanger pedestrians.
