Which lane marking indicates that crossing is not allowed?

The correct answer is a marking that indicates that crossing is not allowed. Specifically, double solid white lines serve to separate lanes of traffic moving in the same direction. They signify that changing lanes is prohibited. This is important for maintaining safe driving conditions, particularly in areas where lane changes could create hazards, such as near exits, entrances, or in high-traffic environments.

The other lane markings mentioned do have distinct meanings. A broken white line indicates that lane changes are permitted, while a solid yellow line generally separates opposing lanes of traffic but may allow turning movements under certain conditions. A single broken yellow line marks the center of a roadway and allows for passing if it is safe to do so. Understanding these markings and their specific limitations help drivers navigate the roads safely and in compliance with traffic regulations.
