What action should be taken when a flashing white light is displayed?

When a flashing white light is displayed, it signals a specific operational condition at an airport, particularly in relation to safety protocols. The appropriate action in this scenario is to return to the start point. This is important because the flashing white light typically indicates that there is a hazard or situation that requires personnel or vehicles to backtrack to ensure safety. It serves as a warning for individuals to reassess their current location and actions to avoid potential risks.

In this context, other actions, like proceeding to the nearest exit or increasing speed, could exacerbate the situation by placing personnel in potentially hazardous zones. Stopping immediately may not address the underlying risk that prompted the signal. Instead, returning to the start point safely allows individuals to reassess and follow up on necessary safety protocols.
