How should you react when encountering a double solid line?

When you encounter a double solid line, it indicates that crossing the line is prohibited. This marking is used to signify that both directions of traffic must remain in their respective lanes without any lane changes. The purpose of these lines is to enhance safety by preventing drivers from making potentially hazardous maneuvers, such as passing another vehicle or switching lanes.

By adhering to the rule of never crossing the double solid line, drivers help maintain orderly traffic flow and reduce the risk of accidents. This is especially significant on busy roads or highways, where crossing these lines could lead to dangerous situations, as drivers do not expect any lanes to be entered or exited. Observing this regulation is crucial in ensuring the safety of all road users.
