A broken yellow line signifies that passing is allowed if it is safe to do so. This marking is used to indicate that drivers may change lanes or pass vehicles on the opposite side of the line, provided they do so without endangering themselves or others on the road. It allows for flexibility in driving and passing situations as long as visibility and road conditions permit safe maneuvering.

The other options relate to different traffic control measures. For instance, a solid line would indicate that lane changes or passing should be avoided, while a no-passing zone is typically marked with additional signage or solid yellow lines, indicating that drivers should remain in their lane. Parks being avoided does not apply to lane markings or traffic signals and is unrelated to the meaning of broken yellow lines. Understanding this helps drivers make informed decisions while on the road, enhancing safety for everyone.
