What do double yellow lines indicate?

Answer: B — You cannot pass in either direction

Double yellow lines serve as a crucial traffic control measure indicating that passing is not permitted in either direction. This means that vehicles must remain in their respective lanes and cannot cross over the lines to overtake another vehicle. The presence of double yellow lines generally signifies that the road may have limited visibility or that it presents a potentially hazardous situation for passing, such as approaching curves or intersections. Understanding the purpose of these lines helps drivers maintain safety on the road by discouraging overtaking where it may be dangerous. Recognizing the importance of adhering to these markings is essential for preventing accidents and ensuring smooth traffic flow.
