On Tuesday, May 31, 2011, approximately 4:55 a.m. eastern daylight time, a 2000 Setra 59-passenger motorcoach operated by Sky Express, Inc., occupied by a driver and 58 passengers, was traveling north on Interstate 95 in the right lane of the three northbound lanes near Doswell, Virginia. The motorcoach drifted from the highway to the right, struck a cable barrier, rotated counterclockwise around its vertical axis, overturned to the right, and rolled onto its roof. The accident investigation focused on the issues of driver fatigue, motorcoach deficiencies in roof strength and occupant protection, and the Federal Motor Carrier Safety Administration (FMCSA) failure to exercise adequate safety oversight of the accident motor carrier. As a result of the investigation, the National Transportation Safety Board makes three new recommendations to the FMCSA, reiterates previous recommendations to the FMCSA and the National Highway Traffic Safety Administration (NHTSA), reclassifies a previous recommendation to the FMCSA, and reiterates and reclassifies a previous recommendation to NHTSA.
