What does a double solid white line indicate?

Answer: B — Passing is prohibited

A double solid white line indicates that passing is prohibited. This means that drivers are not allowed to cross the lines to overtake another vehicle or change lanes. Double solid white lines are typically used in areas where it is unsafe or illegal to pass, such as on curves, hills, intersections, and other areas with limited visibility. It is important to always obey these markings to ensure safety on the road. The other options are not correct because: A. Passing is allowed is incorrect because a double solid white line indicates passing is prohibited. C. Changing lanes is mandatory is incorrect because drivers are not required to change lanes when encountering a double solid white line. D. Speed limit enforced is unrelated to the meaning of a double solid white line.
