What does a solid yellow lane marking indicate?

A solid yellow lane marking indicates that you should not cross the line. This type of marking is used to signify that passing or changing lanes is prohibited, primarily to ensure the safety of all road users. It helps maintain orderly traffic flow and prevents dangerous maneuvers in areas where visibility may be limited or where it is unsafe to cross, such as near intersections or in circumstances where oncoming traffic poses a risk.

The other choices suggest various allowances for crossing or turning, which are incorrect in the context of a solid yellow line. A solid yellow line does not permit crossing for turns or passing; it serves as a clear warning to drivers to remain in their designated lanes for safety considerations.
