Which marking consists of four yellow lines, two solid and two dashed, extending across the width of the taxiway?

• A. Taxiway centerline markings
• B. ILS critical area boundary markings
• C. Runway holding position markings
• D. Stop bars

Answer: (C)

This marks a hold position for runway operations. Across the taxiway you’ll see four yellow lines: two solid lines on the side facing the runway and two dashed lines on the opposite side. The solid lines form the boundary you must not cross without explicit clearance from air traffic control; the dashed lines indicate the side from which you may cross when you’ve been cleared to enter the runway area. This arrangement gives pilots and ground vehicles a clear visual cue to stop and prevents incursions onto active runways. Other options describe different markings: taxiway centerlines guide path along the taxiway, ILS boundary markings mark the protected area around the instrument landing system, and stop bars are red lights. The four-line pattern described here is specifically the runway holding position marking.
