When approaching taxiway holding lines with continuous lines, what should a pilot do?

When a pilot approaches taxiway holding lines marked with continuous lines, the appropriate action is to not cross those lines without prior clearance from Air Traffic Control (ATC). Continuous lines serve as a visual indicator that pilots must stop and wait for explicit authorization from ATC to proceed beyond that point, particularly when it comes to crossing runways. This is critical for maintaining safety and avoiding potential conflicts with other aircraft that may be taking off or landing on adjacent runways.

Understanding the significance of holding lines helps pilots recognize the importance of following standardized procedures and ensuring safe operations on the taxiway. A holding line marked with continuous lines signifies that the area beyond the line is an operational area where the risk of collision is heightened without proper communication and approval from ATC.
