Runway holding position markings consist of four yellow lines, two solid and two dashed, that are painted on the surface and extend across the width of the taxiway to indicate where the aircraft should stop when approaching a runway. Runway Holding Position MarkingNoncompliance with a runway holding position marking may result in the FAA filing a Pilot Deviation against you. You may then proceed with extreme caution. When the tower is closed or you are operating at a nontowered airport, you may taxi past a runway holding position sign only when the runway is clear of aircraft, and there are no aircraft on final approach. Doing so poses a hazard to yourself and others. You should never allow any part of your aircraft to cross the runway holding position sign (either a vertical or surface painted sign) without a clearance from ATC. A common way for the relocated threshold to be marked is a ten foot wide white bar across the width of the runway. It is referred to as a relocated threshold and methods for identifying the relocated threshold vary. When a portion of a runway is closed, the runway threshold is relocated as necessary. Relocated Runway ThresholdIt is sometimes necessary, due to construction or runway maintenance, to close only a portion of a runway.
These are referred to as parallel runways and are distinguished by a letter added to the runway number (e.g., runway 36L (left), 36C (center), and 36R (right)). Certain airports have two or even three runways laid out in the same direction. Runway numbers are in reference to magnetic north. Since aircraft are affected by the wind during takeoffs and landings, runways are laid out according to the local prevailing winds. Refer to Appendix C of this publication for an example of the most common runway markings that are found at airports. A basic VFR runway may only have centerline markings and runway numbers. Runway Markings and SignsRunway markings vary depending on the type of operations conducted at the airport.

Additional information may be found in Chapter 2, “Aeronautical Lighting and Other Airport Visual Aids,” of the Aeronautical Information Manual (AIM). An overview of the most common signs and markings are described on the following pages. All airport markings are painted on the surface, whereas some signs are vertical and some are painted on the surface. It is important for you to know the meanings of the signs, markings, and lights that are used on airports as surface navigational aids. There are markings and signs used at airports that provide directions and assist pilots in airport operations.
