Two solid and two dashed yellow lines across a taxiway, marking a runway boundary.
Also known as: Hold short line, Runway hold line
The runway holding position marking is a set of four yellow lines across a taxiway — two solid and two dashed — marking the boundary of a runway's protected area. The rule is in the pattern: the solid lines face the taxiway side, and an aircraft or vehicle approaching from that side must stop before them unless cleared to cross. Approaching from the dashed side means leaving the runway, and no clearance is needed. Crossing from the wrong side without a clearance is the classic runway incursion.
Marks the boundary of a runway's protected area, and must not be crossed from the taxiway side without a clearance.

Encodes the direction of the rule in its own pattern: the two solid lines always face the side from which a clearance is required, and the two dashed lines face the runway. An aircraft leaving the runway crosses the dashed side and needs no permission.

Is reinforced by a red sign with white lettering carrying the runway designation, mounted at the same point, because a marking on the ground can be obscured by snow, water or a preceding aircraft.

Four lines drawn across the width of a taxiway: two continuous lines side by side, then two broken lines of the same spacing beyond them.
Both are taxiway surface markings.
