A double solid yellow line serves a specific purpose in traffic control and is a clear signal to drivers on the road. It indicates that no passing is allowed in either direction. This means that vehicles cannot cross the line to pass another vehicle, ensuring safety by preventing overtaking in areas where visibility may be limited or where other hazards exist.

This traffic marking is typically found on two-lane roads where the potential for dangerous conditions—such as curves, intersections, or pedestrian zones—would make passing unsafe. On the other hand, the other options suggest different conditions regarding lane use which do not apply to double solid yellow lines. For instance, the allowance for passing or turning, as well as the designation of lanes for bicycles, would be indicated by different road markings or signage. Thus, the presence of a double solid yellow line is an important regulation to help maintain safety on the road.
