What do broken white lines indicate?

Broken white lines on the road signify that crossing the line is permissible, as long as it is done carefully. This marking indicates that the lane is available for changing or merging, reflecting that there are multiple lanes of traffic moving in the same direction. Drivers should always check their mirrors and blind spots to ensure it is safe to change lanes when they encounter a broken white line. The presence of these lines promotes efficient traffic flow while maintaining safety, as it allows drivers to adjust their position without restriction, provided they do so with caution.

The other options relate to different traffic control measures. For instance, a solid line generally suggests that changing lanes or crossing is not allowed, which is contrary to what broken lines indicate. Additionally, one-way traffic is denoted by specific signs or markings that don’t involve broken lines, and maintenance areas are typically indicated with specific markers or barriers to caution drivers.
