Procedures for: c. Entering or crossing runways
Bottom line
Do not enter a runway at a towered airport unless instructions are given from ATC to cross, takeoff from, or “line up and wait” on that specific runway. Scan the full length of the runway and the final approaches before entering or crossing any runway, even if ATC has issued a clearance.
