During taxiing, what does a flashing white light from the control tower indicate?

• A. move clear of the runway/taxiway immediately
• B. OK to proceed but use extreme caution
• C. return to starting point
• D. test the brakes

Answer: (C)

A flashing white light from the control tower while taxiing means you should return to your starting point on the airport. This signal is part of the ground light signaling system pilots use to move or reposition when radio contact isn’t available. It specifically directs you to taxi back to where you began, rather than continuing, stopping abruptly, or performing any other action.
