Which of the following lines permits the passing of other vehicles?

A broken white line indicates which lanes are used for moving in the same direction and permits drivers to change lanes or pass other vehicles when it is safe to do so. This type of line is typically found on multi-lane roads, where vehicles can move freely between lanes to overtake slower traffic or to navigate around obstacles.

In contrast, a solid yellow line generally indicates that passing is not allowed, as it separates traffic moving in opposite directions. Similarly, a double solid white line signifies that lane changes are prohibited, adding to the constraints for drivers on that roadway. The broken yellow line also allows for passing, but it only applies when there is no oncoming traffic; however, the question specifically asked about lines that permit passing in a more general sense, making the broken white line the best choice.
