Broken or dashed white lines mark traffic lanes on roads with more than one lane moving in which direction?

Broken or dashed white lines are specifically used to indicate that multiple lanes are moving in the same direction. This type of line allows drivers to change lanes safely when it is clear to do so. When drivers see these lines, they understand that they can pass or shift to another lane while remaining aware of surrounding traffic.

In contrast, solid white lines signify that lane changes are discouraged or prohibited in that area, while dashed yellow lines indicate lanes moving in opposite directions. The other options do not accurately describe the purpose of broken or dashed white lines, as they pertain to either opposing lanes of traffic or situations unrelated to lane changes. This distinction is crucial for maintaining traffic flow and ensuring safety on the roads.
