What does a dual solid taxiway edge marking indicate?

• A. Centerline of taxiway
• B. Edge of the usable surface for taxiing (not to be crossed)
• C. Boundary of pavement
• D. Do not taxi

Answer: (C)

Dual solid taxiway edge markings mark the boundary of the paved surface. They run along the sides of the taxiway to show where the usable pavement ends, signaling that areas beyond are not intended for aircraft operations. This helps pilots stay on the paved area and avoid the shoulder or unpaved terrain, which may not support aircraft weight or be safe to cross. It’s a boundary indicator, not a centerline cue or a direct prohibition—those would be conveyed by different markings or signage.
