What Happened

​​This information is preliminary and subject to change. Release date: 2 August 2023​


​​On Wednesday, July 12, 2023, about 1:48 a.m. central daylight time, a 2014 Prevost 50-passenger motorcoach with 21 occupants was westbound on Interstate 70 (I-70), near Highland, Madison County, Illinois. The motorcoach was owned and operated by Greyhound Lines, Inc., and was on a scheduled route (route number 1675) from Indianapolis, Indiana, to St. Louis, Missouri. As the motorcoach approached the westbound Silver Lake rest area near mile marker 27.4, the motorcoach departed I-70 onto the rest area exit ramp, where it collided with three truck-tractor semi-trailer combination units that were parked on the ramp’s right shoulder (see figure 1). As a result, three motorcoach passengers were fatally injured. The driver and remaining motorcoach passengers sustained injuries ranging from minor to serious. The three tractor-trailer drivers, who were inside the combination vehicles at the time of the crash, were uninjured.

At the crash location, I-70 is a four-lane divided highway with the eastbound and westbound lanes separated by a depressed earthen median. The posted speed limit on I-70 is 70 mph, and the exit ramp had a posted advisory speed limit of 40 mph.

The westbound Silver Lake rest area was constructed in 1973 and had a total of 64 designated parking spaces. Of these, 21 were designated as commercial truck parking spaces, with one of those being a commercial truck handicap space.

  • ​Federal Motor Carrier Safety Administration
  • Illinois State Police
  • Illinois Department of Transportation
  • Highland-Pierron Fire Protection District​
  • City of Highland Fire Department

All aspects of the crash remain under investigation while the NTSB determines the probable cause, with the intent of issuing safety recommendations to prevent similar events.
