Which color lines mark the boundaries of movement areas?

The solid and dashed yellow lines are used to mark the boundaries of movement areas at airports. Solid yellow lines indicate the separation between the movement area and non-movement area, guiding aircraft and vehicle operators to remain within designated pathways. This is critical for safety, as it prevents unauthorized or unintentional entry into active runways or taxiways.

Dashed yellow lines signify a place where it is permissible to cross onto a different movement area, thus indicating transitions between different operational zones. This color coding is standardized in airport operations, helping to maintain clear visual communication of safety requirements on the ramp and runways.
