What does a double yellow line indicate?

A double yellow line indicates that no passing is allowed in either direction. This is a crucial traffic regulation designed to enhance safety on the roads, particularly in areas where visibility is limited or where there may be an increased risk of collisions. The presence of double yellow lines serves as a clear signal to drivers that it is unsafe to enter the opposing lane to pass another vehicle, promoting safer driving practices and reducing the likelihood of accidents. Understanding this traffic marking is essential for all drivers to navigate roads safely and responsibly.
