What does a double yellow line indicate?

A double yellow line indicates that no passing is allowed in either direction. This road marking serves as a strong visual signal to drivers, indicating that it is unsafe to cross these lines to overtake another vehicle. The rationale behind this traffic regulation is to enhance safety, particularly in areas where visibility is limited or where road conditions make passing dangerous.

In a situation where a road has a double yellow line, drivers are expected to remain in their lanes and avoid any maneuver that would cross these lines. This helps prevent head-on collisions and ensures smoother traffic flow, thereby contributing to overall road safety. Understanding this traffic sign is crucial for maintaining safe driving practices and adhering to road rules.
