What does it indicate when the control tower shines a flashing red light at you?

When the control tower shines a flashing red light at you, it specifically indicates that you need to vacate the runway immediately. This signal is a direct instruction from air traffic control to ensure the safety of all aircraft and ground personnel involved.

The flashing red light serves as an urgent warning that there may be an imminent hazard, such as another aircraft landing, an emergency situation, or other operational needs that require the runway to be clear. Understanding this signal is critical for maintaining safety in the airside area of the airport.

Other signals, such as a steady red light or different flashing patterns, convey other messages related to caution or instructions regarding movement on the airfield, but the flashing red light is unequivocal in its command to vacate the runway without delay. Therefore, recognizing and responding appropriately to a flashing red light is essential for all airside vehicle operators.
