What does a broken white line on the roadway signify?

A broken white line on the roadway signifies that lanes of traffic moving in the same direction may be changed. This means that drivers are permitted to switch from one lane to another, which provides flexibility for maneuvers such as passing or merging into another lane. The broken line visually indicates that it is safe to make these adjustments, as long as it is done cautiously and with consideration for other vehicles. It delineates the lanes without indicating any restriction on movement, unlike solid lines, which indicate that lane changes are prohibited.

The other answer options do not accurately represent the meaning of a broken white line. For example, cross traffic being allowed does not pertain specifically to how the lanes for traffic moving in the same direction are organized. Additionally, while end of lane markings and roadwork symbols are important, they would be represented by different types of lines or signs rather than a broken white line.
