Instrument (INST) Holdline is defined by which markings?

• A. Two horizontal yellow solid lines perpendicularly connected by pairs of solid yellow lines with 'INST' on the runway side
• B. A single yellow dashed line across the runway
• C. A white crosswalk-like marking
• D. A pair of red lines with 'INST' marking

Answer: (A)

Instrument hold lines mark where you must stop on the taxiway before entering the instrument approach area. The familiar pattern is two solid lines on the runway side and two dashed lines on the opposite side, across the taxiway, with the word INST painted on the runway side. The solid lines show the boundary you may not cross until you’re cleared; the dashed lines indicate the side you would cross from if you’re authorized. The INST label makes it clear this hold position is specifically for instrument approach procedures. So the described marking—the INST label on the runway side with the double-line pattern across the taxiway—identifies the instrument hold location. Other markings described do not represent the instrument hold pattern.
