What does a standard hold-short line consist of?

• A. Four dashed lines
• B. Four solid lines
• C. One solid and three dashed lines
• D. Two solid lines and two dashed lines

Answer: (D)

A standard hold-short line uses a mix of solid and dashed lines to show where to stop and where crossing is allowed with clearance. The two solid lines form the boundary you must not cross without explicit clearance, while the two dashed lines on the other side indicate the portion from which crossing may be permitted when cleared. This configuration is placed at runway/taxiway intersections to prevent runway incursions. So two solid lines and two dashed lines is the correct description. The other patterns don’t match how this hold-short boundary is marked.
