What do double solid center yellow lines indicate?

Double solid center yellow lines indicate that no passing is permitted. This road marking serves as a clear visual cue for drivers, signaling that both lanes of traffic are not allowed to cross those lines to overtake another vehicle. This regulation is primarily in place for safety reasons, especially in areas where visibility may be limited or in proximity to hazards like intersections or curves.

In contrast, the other choices suggest various driving behaviors that are not permissible when double solid yellow lines are present. For instance, passing is explicitly forbidden, which eliminates the possibility of the other scenarios mentioned. This ensures that all drivers understand the importance of maintaining safety by not attempting to pass when it could lead to dangerous encounters with oncoming traffic.
