Which type of lines restrict traffic from crossing when they are double solid?

• A. Broken yellow lines
• B. Solid white lines
• C. Double solid white lines
• D. Broken white lines

Answer: (C)

Double solid white lines indicate that crossing over these lines is prohibited. These lines are typically used to separate lanes of traffic traveling in the same direction, where changing lanes is not allowed due to safety concerns. The presence of double solid lines signifies that it is illegal for drivers to cross them, ensuring the safety and smooth flow of traffic by preventing potentially dangerous lane changes. In contrast, broken lines—whether yellow or white—allow for lane changes when it is safe to do so. Solid white lines do serve a purpose in maintaining lane discipline, but they do not impose the same strict prohibition on crossing as double solid lines do. Therefore, double solid white lines distinctly communicate the restriction on crossing to all drivers.
