Which of the following is true regarding the crossing of broken white lines on the roadway?

Crossing broken white lines on the roadway is permissible when changing lanes. This type of line is used to separate lanes of traffic moving in the same direction. The designation of broken lines indicates that lane changes are allowed, provided it is safe to do so and the driver is signaling their intention to switch lanes.

The other options involve misconceptions about the rules surrounding broken white lines. For example, crossing them is not prohibited, which refutes the first choice. Additionally, broken white lines do not indicate illegal parking zones; that function typically belongs to solid lines or different color markings. Therefore, the assertion that all options are correct is inaccurate.

Understanding these distinctions is crucial for safe driving and adhering to traffic laws.
