What does a solid yellow line next to a broken centerline signify?

A solid yellow line next to a broken centerline indicates that passing is not allowed from the lane nearest the solid yellow line. This traffic marking is designed to enhance safety by signaling that, although passing is permissible for traffic traveling in the opposite lane (where the broken line is present), drivers in the lane next to the solid yellow line must refrain from passing. This helps prevent potential collisions and maintains a safer driving environment.

The other choices do not accurately represent the meaning of this road marking. For example, allowing passing from either lane contradicts the purpose of the solid yellow line, which restricts passing for one side. Similarly, the notion that only motorcycles can pass or that passing is only permitted during daylight does not align with the established traffic laws related to these markings.
