Accident Report Detail

​About 6:40 p.m. daylight savings time, on Monday, August 28, 2006, a 2000 Motor Coach Industries, Inc. (MCI), 45-foot, 55-passenger motorcoach operated by Greyhound Lines, Inc. (Greyhound), transporting 52 passengers and the driver, was traveling northbound on Interstate 87 (I-87) near Westport, New York. The motorcoach had departed the Port Authority terminal in New York City about 1:00 p.m. and was en route to its final destination of Montreal, Quebec. The weather was partly cloudy and the roadway was dry.

​The National Transportation Safety Board determines that the probable cause of this accident was the failure of the left-steer-axle tire, due to an extended period of low-pressure operation, which resulted in overheating and tread separation, leading to loss of vehicle control. Contributing to the accident was the imbalanced brakes, which enhanced the vehicle’s counterclockwise rotation and loss of control when applied by the driver. Also contributing to the severity of passenger injuries was the lack of occupant protection standards for motorcoaches.
