What do double solid lines in the middle of a roadway signify?

Double solid lines in the middle of a roadway indicate a no passing zone. This means that vehicles are prohibited from crossing these lines to overtake other vehicles. The purpose of this restriction is to enhance safety in areas where visibility may be limited or where potential hazards exist, such as curves, hills, or intersections.

By adhering to this rule, drivers help ensure the safety of themselves and others by preventing risky maneuvers that could lead to accidents. The presence of double solid lines is a clear visual cue for drivers to stay in their lane and refrain from passing, distinguishing it from other road markings that allow or indicate passing zones. Understanding this traffic control is critical for maintaining safe driving practices.
