In tower light-gun signals, which signal instructs a vehicle to proceed or go?

Explanation:
Steady green is the go signal from the tower. It tells a vehicle on the movement area that it’s allowed to proceed—taxi, cross, or continue moving as cleared by air traffic control. This provides a clear authorization to continue, which is exactly what “proceed/go” requires. Steady red means stop, flashing red indicates the runway or taxiway must be cleared, and flashing white directs the operator to return to the starting point. These signals are used when radio communication isn’t available to ensure safe coordination on the airfield.
