What does a double solid white line indicate?

A double solid white line is a road marking that indicates crossing the line is prohibited. This is typically seen in areas where lane changing is not allowed, such as:

• At the edges of certain roadways where maintaining the current lane is essential for safety.

• In areas such as highways or roads near construction zones where erratic lane changes could cause accidents.

Drivers are expected to remain in their lanes when they encounter a double solid white line, ensuring orderly traffic flow and reducing the risk of collisions. In contrast, options that suggest crossing the line to change lanes or that imply travel directions on either side are permissible do not align with the intended meaning of this specific road marking.
