What does a double yellow line indicate?

A double yellow line indicates that no passing is permitted in either direction. This marking is commonly used on roadways to enhance safety and maintain order among vehicles. The purpose of a double yellow line is to signify a clear division between opposing directions of traffic, alerting drivers that it is unsafe to cross over to the opposite lane to overtake another vehicle. This is particularly important in areas where visibility is limited, such as curves or hills.

When drivers encounter a double yellow line, it serves as a reminder to adhere strictly to traffic regulations designed to prevent accidents and promote a smoother flow of traffic. Recognizing this signal is vital for safe driving practices and understanding roadway rules.
