Summary

This National Transportation Safety Board (NTSB) report investigates a fatal motorcoach accident that occurred on June 20, 1998, on the Pennsylvania Turnpike near Burnt Cabins. A Greyhound Lines motorcoach, traveling westbound from New York City to Pittsburgh, departed the roadway and struck two parked tractor-semitrailers in an emergency parking area. The collision resulted in seven fatalities—the bus driver and six passengers—and injuries to 16 passengers and two truck occupants. The investigation was motivated by the need to determine the probable cause and identify systemic safety issues regarding driver performance, carrier oversight, highway design, and emergency response. The NTSB conducted a comprehensive investigation utilizing factual data reconstruction, vehicle forensic analysis, and operational review. Investigators analyzed the bus’s Engine Electronic Control Module (ECM) and Voice Response Unit (VRU) to reconstruct the driver’s activity and speed, revealing the bus had been driven at speeds up to 76 mph on the day of the accident and up to 90 mph in the preceding 90 days. The study also examined the driver’s medical history, toxicology reports, and employment records, alongside an assessment of Greyhound’s scheduling practices and compliance oversight. Additionally, the report evaluated the design and usage of Pennsylvania Turnpike pull-off areas and the effectiveness of the multi-agency emergency response. The NTSB determined the probable cause was the bus driver’s reduced alertness, resulting from the ingestion of a sedating antihistamine and fatigue caused by irregular work-rest periods scheduled by Greyhound. Contributing to the accident’s severity was the Pennsylvania Turnpike Commission’s practice of permitting nonemergency parking in pull-off areas within the highway clear zone. The investigation identified several major safety issues: inadequate carrier oversight of driver behavior and scheduling, the inappropriate use of emergency pull-off areas for routine truck parking, the lack of motorcoach emergency interior lighting and retroreflective signage, and deficiencies in disaster preparedness and emergency response management. The report concludes with recommendations to the National Highway Traffic Safety Administration, the Pennsylvania Turnpike Commission, Greyhound Lines, the United Motorcoach Association, and the American Bus Association. These recommendations aim to improve driver monitoring systems, enhance the design and regulation of highway pull-off areas, mandate better emergency lighting and signage on motorcoaches, and standardize emergency response protocols. The findings highlight the critical intersection of human factors, corporate oversight, and infrastructure design in preventing severe highway accidents.

Key finding

The probable cause of the accident was the busdriver's reduced alertness resulting from ingesting a sedating antihistamine and from his fatigued condition resulting from Greyhound Lines, Inc., scheduling irregular work-rest periods.
