In the center lane of a two-lane road, what does a solid line with a broken line beside it indicate when you are on the broken line side?

A solid line with a broken line beside it indicates specific rules for passing on a roadway. When you are on the side of the broken line, it means that you may legally pass vehicles in your lane. This configuration is designed to allow for passing when it is safe to do so, as the broken line signifies that you have the option to change lanes for passing, while the solid line serves as a boundary for the other lane where passing is not allowed.

This arrangement helps maintain safety by indicating that the side with the solid line is restricted to prevent vehicles from crossing into the broken line area, which enhances the safety of traffic flow. Therefore, with the broken line beside you, you have the opportunity to pass vehicles in your own lane, assuming it is safe to do so.
