Which statement about hold-short line crossing clearance is correct?

• A. Crossing clearance is not required if the area is clear.
• B. Crossing clearance is required only after a stop at the line.
• C. Crossing clearance is granted automatically if you are on time.
• D. Crossing clearance is required only when ATC has issued a crossing clearance.

Answer: (D)

Crossing a hold-short line requires explicit permission from ATC. The line marks a boundary where crossing into another area (often onto a runway or another taxiway segment) can create a risk of runway incursions, so you can’t cross without clearance. ATC will issue a specific crossing clearance when they want you to proceed, and without that instruction you must remain before the line, even if the area appears clear or if you are on time. The idea is that the right to cross is granted only by ATC, not automatically or by any rule of thumb.

So, the statement is correct because crossing clearance is granted only when ATC has issued it.
