What does a double solid yellow line indicate?

A double solid yellow line on the road signifies that no passing is allowed in either direction. This marking is used primarily on roads where visibility may be limited or where it's unsafe to overtake another vehicle, ensuring that all traffic remains within its lane. The purpose of this regulation is to enhance safety by preventing dangerous maneuvers that could lead to collisions. It is important for drivers to recognize and adhere to such road markings to maintain safe driving conditions.
