Which marking indicates the position to hold at an airport?

The hold position marking designates the precise location where vehicles and aircraft must stop at an airport. This marking is critical for maintaining safety on the airfield, as it prevents incursions onto active runways and taxiways. The hold position marking typically consists of two solid lines and two dashed lines, signaling pilots and ground vehicles when they are permitted to cross or must stop. Proper recognition and adherence to this marking are vital in managing the flow of air traffic and ensuring safe operations.

In contrast, boundary markings indicate the limits of the airport property, next runway markings guide traffic towards the upcoming runway, and takeoff markings serve to identify where takeoff clearance should be obtained. While these markings play important roles in airfield operations, they do not specify the stop position for airplanes or vehicles, which is the primary function of the hold position marking.
