At a recent board meeting, the National Transportation Safety Board (NTSB) determined that driver fatigue, inadequate company oversight, and a lack of safe truck parking along the National Highway System led to a fatal collision on Interstate 70 (I-70) in Highland, IL., during the summer of 2023.

In the early morning hours on July 12, 2023, a Greyhound motorcoach traveling westbound departed I-70 for the Silver Lake Rest Area, where it crashed into three tractor-trailers parked on the right shoulder of the exit ramp.

As a result of the crash, three motorcoach passengers were killed, and the driver and 11 passengers sustained injuries. However, the truck drivers walked away with no injuries.

"This crash was as tragic as it was preventable," NTSB Chairman Jennifer Homendy said. "Our investigation brought to light a critical shortage of safe truck parking and made clear a painful lesson: until we address this important safety issue, lives are at risk on our nation's roads."

NTSB Outlines Contributing Factors, Calls for Action

During the meeting, NTSB investigators and board members discussed the crash, focusing on the multiple safety issues that, had they been addressed, may have lessened the severity or prevented the crash entirely. These include:

• ​​Motorcoach driver fatigue.

• Deficient driver oversight by Greyhound, including a lack of a progressive discipline policy, a lack of adequate record-keeping, and a lack of policies for implementing driver monitoring systems.

• Insufficient federal guidance on safety management, driver coaching, and fatigue mitigation.

• Lack of seat belt use by the motorcoach passengers.

• Crash risk from lack of truck parking availability along the National Highway System.

After investigating, NTSB is issuing 11 new recommendations and two reiterated recommendations to the U.S. Department of Transportation, the Federal Motor Carrier Safety Administration (FMCSA), Greyhound Lines, the National Coalition on Truck Parking, the American Bus Association, and the United Motorcoach Association.

Additionally, the NTSB is reiterating two safety recommendations previously issued to FMCSA.

An executive summary containing the probable cause, investigation findings, and approved safety recommendations is available on the investigation web page. The final report will be published on the NTSB's website in the coming weeks.
