What does it mean when there are two solid yellow lines in the center of the road?

When there are two solid yellow lines in the center of the road, it indicates that passing is not permitted in either direction. This road marking serves as a critical safety measure, signaling to drivers that it is illegal to cross these lines to overtake another vehicle. The two solid lines emphasize the importance of maintaining a safe distance from oncoming traffic, especially in areas where visibility may be limited or where there could be other hazards, such as pedestrians or intersections. Recognizing this symbol helps drivers make safer decisions on the road and contributes to overall traffic safety.
