What does a broken white line signify on the road?

A broken white line on the road indicates that lane changes are permitted, provided it is safe to do so. This means that drivers can move between lanes when there is no oncoming traffic or obstacles, allowing for greater flexibility in managing the flow of traffic. The presence of a broken line suggests that the particular lane is not restricted, unlike solid lines, which would prohibit lane changes. Therefore, it is important for drivers to be vigilant and ensure that such movements are safe before proceeding.

Other answer options are related to restrictions or behaviors that do not apply to a broken white line. For example, a solid white line would indeed signify that lane changes should not occur, and safety considerations for wet conditions would be addressed differently in terms of road markings.
