What does a solid yellow line next to a broken yellow line indicate?

A solid yellow line next to a broken yellow line indicates that no passing is allowed on the side of the road where the solid line is painted. This means that if you are traveling in a lane that has the solid yellow line, you must not cross it to pass another vehicle. On the other hand, if you are in the lane with the broken yellow line, you are permitted to pass when it is safe to do so.

This marking is designed to help drivers understand when it is safe to overtake another vehicle and when it is not, promoting safer driving practices. Passing on a solid yellow line poses a greater risk, as it typically indicates a more hazardous situation, such as a curve or intersection where visibility may be limited.
