What does a double solid yellow line indicate?

• A. You may pass from your side only
• B. You may pass oncoming traffic if you are to the right
• C. You may not pass from either direction; you should stay in your lane.
• D. You may change lanes freely

Answer: (C)

Double solid yellow lines indicate a no-passing zone for traffic in both directions. They separate two-way traffic, and you must not cross the lines to pass another vehicle, because you could move into the path of oncoming traffic. The safest action is to stay in your lane and wait until you reach a section where passing is legal, such as a dashed line, or when it’s clearly safe to pass. Crossing these lines to overtake is dangerous and increases the risk of a head-on collision, which is why these lines are used in areas where visibility or road conditions make passing unsafe.
