What does a broken white line signify on the roadway?

A broken white line on the roadway indicates that vehicles may cross the line to change lanes when it is safe to do so. This type of line is used to separate lanes of traffic moving in the same direction, allowing for safe and controlled lane changes. Drivers are advised to use their turn signals and ensure that the lane they are moving into is clear before making the maneuver.

The other choices do not accurately describe the function of a broken white line. For instance, a solid line would indicate that lane changes are prohibited, which is not the case with a broken line. Lane separation for traffic moving in opposite directions would typically be marked with a solid yellow line rather than a broken white line. Lastly, indications such as a stop sign ahead would not be indicated by any type of line on the roadway; rather, stop signs are standalone signage specifically designed to inform drivers of a stop intersection.
