What does a single yellow dashed line typically indicate?

A single yellow dashed line is an important marking on airport taxiways. It indicates a taxiway intersection line, which is designed to guide pilots and vehicle operators as they navigate through intersections. This line makes clear where the taxiways intersect, helping to alert operators to be vigilant and prepared to give way to any aircraft that may be on the intersecting path. Understanding this marking is crucial for maintaining safety on the airside, as it ensures that both vehicles and aircraft can share the space without confusion.

In contrast, the other options represent different airside markings or areas. For instance, an area under construction would typically be marked with clear signs and barriers, while runway holding positions are indicated by solid and dashed lines, commonly painted in white, not yellow. A parking area would be indicated by different signage and markings designed specifically for those purposes. Thus, recognizing the specific role of the single yellow dashed line helps in navigating the complexities of airside operations effectively.
