On Saturday, May 14, 2016, shortly before 11:24 a.m., central daylight time, a 1998 Van Hool 49-passenger motorcoach, operated by OGA Charters LLC of San Juan, Texas, was traveling northbound on US Highway 83 near Laredo, Texas. The motorcoach entered a horizontal curve to the right, and, as it moved through the curve, it drifted from its lane to the left. After the motor-coach drifted left, the driver steered to the right and applied the brakes, which resulted in the vehicle’s loss of control, so that it slid and yawed clockwise. The motorcoach departed the right, or east, side of the highway and, after entering the earthen right-of-way, overturned onto its left side. Nine passengers died, 36 passengers experienced minor-to-serious injuries, and the motorcoach driver and trip coordinator were treated for minor injuries. The injury severity for five passengers could not be determined. The investigation focused on the following safety issues: inadequate federal oversight and guidance for commercial drivers with diabetes treated without insulin; inaccurate and incomplete highway maintenance record-keeping by the Texas Department of Transportation (TxDOT); need for improved training for TxDOT maintenance workers; need for increased motorcoach crash-worthiness through improvements to window glazing and retention; driver fatigue resulting from poor safety management by OGA Charters and inadequate federal safety ratings for passenger motor carriers with repetitive safety violations in the area of driver performance. As a result of this investigation, the National Transportation Safety Board (NTSB) makes new safety recommendations to Federal Motor Carrier Safety Administration (FMCSA) and TxDOT. The NTSB also reiterates two recommendations to the FMCSA and one recommendation to the National Highway Traffic Safety Administration. |
