What does a double yellow line signify on the road?

A double yellow line on the road signifies that no passing is allowed. This marking indicates that there are conditions where it is unsafe to overtake other vehicles, usually due to visibility limitations, curves, or intersections. By maintaining this regulation, traffic flow is controlled, and driver's safety is prioritized, making it crucial for motorists to adhere to this rule.

This marking clearly communicates to drivers that they must remain in their lane and cannot cross the lines to pass other vehicles, thereby reducing the risk of accidents that may result from improper passing maneuvers. Understanding this signage is essential for any driver to ensure they follow the rules of the road and maintain safety for themselves and others.
