Runway incursion.

Bottom line

A runway incursion is any occurrence at an airport involving an aircraft, vehicle, person, or object on the ground that creates a collision hazard or results in a loss of separation with an aircraft taking off, landing, or intending to land. At a towered airport, runway hold markings should never be crossed without explicit ATC instructions.
