What does a double solid white line indicate?

A double solid white line indicates that no changing of lanes is allowed. This marking is used to convey a clear message to drivers that they must remain in their lane and not cross over to the adjacent lanes. The presence of a double solid white line is often found in areas where lane changes could be hazardous, such as near intersections or sections of road with frequent pedestrian traffic. The purpose of this restriction is to enhance safety by preventing unpredictable movements that could lead to accidents or create confusion among drivers.

While separating lanes of traffic moving in the same direction is accurate, crossing or changing lanes is prohibited, which is the primary rule communicated by the double solid white line. The other options refer to different traffic scenarios that do not apply to the meaning of double solid white lines.
