Which line indicates no passing in either direction?

Which line indicates no passing in either direction?

• A. A solid white line
• B. A dashed white line
• C. A solid yellow line
• D. A double solid yellow line

Answer: (D)

Passing rules shown by lines guide safe decisions on two-lane roads. A double solid yellow line means no passing in either direction. It’s placed where visibility is limited or hazards make crossing into the oncoming lane dangerous, so drivers on both sides must stay in their lane and not attempt to pass. In contrast, a solid white line signals you should stay in your lane or not cross the line, while a dashed white line indicates you can pass or change lanes when it’s safe. A single solid yellow line means you can’t pass in your direction unless the line on your side is dashed elsewhere, but it doesn’t prohibit all passing for both directions like the double solid does.
