What does a double solid yellow line indicate?

Answer: C — No passing in either direction

A double solid yellow line indicates that no passing is allowed in either direction. This road marking serves as a strong cautionary measure to enhance safety on the roadway. It is used in areas where visibility is limited or where it is particularly hazardous to attempt to pass another vehicle, such as on curves, hills, or intersections. The presence of a double solid line reinforces the importance of adhering to safe driving practices, ensuring that drivers remain in their lanes and do not attempt to overtake vehicles when it could lead to dangerous situations. This marking is a clear and enforceable restriction intended to prevent accidents and to maintain a safe flow of traffic.
