Where is the holding position marking?
These runway holding position markings act as the border between taxiway and runway. At an airport with an air traffic control tower, a pilot may not cross the runway holding position marking until cleared to do so by the air traffic controller.

For a perpendicular intersection, the location of the runway holding position marking ranges from 125 feet to 280 feet from the centerline of the intersecting runway.
