What does a broken yellow line on a roadway signify?

A broken yellow line on a roadway signifies that traffic is moving in opposite directions and that crossing the line is permitted. This marking indicates that drivers have the option to pass slower vehicles when it is safe to do so. It is essential for drivers to exercise caution while crossing this line, as they must ensure that the maneuver can be completed safely without interfering with oncoming traffic.

In contrast, solid lines, either yellow or white, generally indicate restrictions on crossing and are designed for safety to keep vehicles in their respective lanes. The context provided by the broken yellow line is crucial for drivers to understand that there is a level of flexibility regarding lane changes and passing, contrasting with lines that prohibit such actions.
