What does a double solid yellow line indicate in terms of passing?

• A. You may pass from your direction; you should stay in your lane.
• B. Passing allowed when clear
• C. Only left-to-right passing allowed
• D. You may not pass from either direction; you should stay in your lane.

Answer: (D)

A double solid yellow line means no passing in either direction. These lines are placed where sight distance is limited or the risk of a head-on collision is high, such as on curves or hills, so you should stay in your lane and not cross the line to pass, even if the vehicle ahead is slower. If you see a dashed line on your side later or farther ahead, passing may be allowed there when it’s safe, but a double solid line itself indicates passing is not allowed from either direction. This helps keep traffic moving safely and reduces the chance of crashes in poor visibility or restricted sight distance.
