United 737 Runway Incursion while Vacating

A United Boeing 737-800, registration N87507 performing flight UA-1941 from Tucson, AZ to Denver, CO (USA), had landed on Denver’s runway 35L and slowed to taxi speed. The aircraft turned into a high speed turn off M6 but was not able to follow the turn radius and slid off coming to a stop ahead of the shortstop line inside the runway protected area with the nose gear on the soft ground north of the taxiway at 18:21L (01:21Z Nov 18th). The passengers disembarked through the rear left door and a mobile stair onto the taxiway and were bussed to the terminal.
