What does a broken white line indicate on the road?

A broken white line on the road indicates that drivers may change lanes, but it is essential to do so safely. This marking serves as a guideline that allows for lane changes, signaling that there is no prohibition against moving from one lane to another. However, it is crucial for drivers to ensure that it is safe to make such maneuvers by checking mirrors and blind spots, thus promoting safe driving practices.

The other choices highlight restrictions that are not applicable to a broken white line. Stopping before changing lanes is not required with this type of marking, and it does not signify a no-passing zone or that lane changes are entirely prohibited. This clear indication helps maintain smooth traffic flow while promoting safety on the roads.
