What does a double solid line indicate?

A double solid line indicates that crossing or passing is not allowed. This roadway marking is a critical safety feature designed to prevent drivers from changing lanes or overtaking other vehicles in areas where it would be unsafe to do so. The presence of a double solid line often signifies that visibility is limited, or that there are specific hazards ahead, such as intersections, pedestrian crossings, or areas with high traffic. Drivers should adhere strictly to this marking, as it helps maintain safe and orderly traffic flow.
