A solid yellow line on your side of the road indicates that passing is not allowed. This marking serves as a clear visual warning to drivers that they should not cross the line to overtake another vehicle. The presence of this line is crucial for maintaining road safety, particularly in areas where visibility may be limited or the road configuration is such that passing would be dangerous.

In contrast, the other options suggest scenarios that do not align with the purpose of a solid yellow line. For example, allowing parking or designating a bike lane would typically use other forms of markings, while a line that indicates passing is permissible would be broken or dashed. Understanding these markings and their implications helps drivers to make safer choices on the road.
