What happens if there's a solid yellow line in the center of the road?

Answer: C — It means passing is not allowed

A solid yellow line in the center of the roadway indicates that passing is not allowed for vehicles traveling in either direction. This marking serves a crucial safety purpose, signaling to drivers that the road conditions—such as visibility or the proximity of oncoming traffic—do not permit safe overtaking maneuvers. It is a clear visual cue intended to prevent accidents that could arise from unsafe passing behavior. Understanding this rule is vital for maintaining safety on roadways. A driver should always respect a solid yellow line and remain in their lane without attempting to pass other vehicles to avoid potential collisions.
