What is the correct interpretation of a solid double yellow line on the road?

• A. No passing in either direction.
• B. Passing is allowed with caution.
• C. Passing is limited to daytime.
• D. They indicate the left edge of the pavement.

Answer: (C)

A solid double yellow line marks a center divider between opposite directions of traffic and means you may not pass another vehicle in either direction. This rule applies at all times, so passing is not allowed just because you think the other car is slow or there’s a gap. The purpose of the double yellow is to prevent unsafe passing where visibility or road conditions may be poor. The line does not indicate the left edge of the pavement—that’s shown by a different marking (typically a white edge line). That’s why the option about the left edge isn’t correct, and it’s not related to daytime limits.
