What does a steady green signal indicate for vehicles?

• A. Steady red = stop
• B. Steady green = proceed/go
• C. Flashing red = clear runway/taxiway
• D. Flashing white = return to start

Answer: (B)

Signals on the airport surface use color and steadiness to guide drivers, with steady green specifically telling you to move forward. When you see a steady green, you have clearance to proceed along your taxi route as directed by ATC, but you should keep scanning for other traffic and be ready to stop if ATC or conditions change. The other signals indicate different actions—steady red means stop, and flashing signals signal caution or special instructions (the exact meaning can vary by airport procedures). The important idea is that steady green equals go.
