The snowplow driver had been plowing snow on an airport service road. When he finished, the driver departed for another area of the airport that needed plowing, which required crossing a taxiway and active runway. The driver stopped short of the taxiway, but without ATC or airport operations clearance, crossed the runway. The driver saw a landing airplane as he was crossing the runway and increased acceleration. The flight crew saw the snowplow holding short of the taxiway. They landed, but during the landing roll, they saw the snowplow cross in front of them. "Significant" reverse thrust and brakes were used to bring the aircraft to a halt on the runway. The ground controller did not see the snowplow, but was alerted to the runway incursion by the flight crew's report. The Airport Movement Area Safety System (AMASS) was operational, but no alarm sounded.
Probable Cause: The snowplow driver's failure to follow procedures/directives by crossing an active runway without clearance, resulting in a runway incursion and near collision with an airplane during its landing roll.
