What does a yellow dashed line signify regarding crossing?

A yellow dashed line indicates that passing is permitted, but only for drivers whose side of the roadway has the dashed line. It means that if the yellow line is dashed on your side, you are allowed to cross over it to pass another vehicle when it is safe to do so. This marking is designed to enhance roadway safety by highlighting where overtaking is permitted while also indicating caution, as it remains important to assess oncoming traffic and ensure clear visibility.

The other options do not accurately reflect the meaning of a yellow dashed line. Specifically, a prohibition to cross at any time, or stating that it can never be crossed, contradicts the fundamental purpose of dashed lines, which facilitate safe passing. Also, limiting crossing to emergency situations would not align with the typical traffic rules regarding dashed lines, which allow for regular passing under appropriate conditions.
