The Mustang driver, a 22-year-old man from Coopersburg, was pronounced dead at the scene. A 21-year-old woman from Massachusetts who was riding as a passenger in the Mustang was injured and transported to a local hospital, as reported by WGAL.
Truck Driver Not Injured, Highway Closed for Hours
Authorities said the tractor-trailer driver, a man from New Holland in Lancaster County, was not injured. All eastbound lanes of I-78 were shut down after the crash and reopened at approximately 5:45 a.m. Friday.
State police said the crash remains under investigation. Anyone who witnessed the incident or has dashcam video was asked to contact the Pennsylvania State Police Fogelsville station and reference incident number PA26-519851.
Evidence in Late-Night Tractor-Trailer Crashes
Crashes between passenger vehicles and tractor-trailers are often catastrophic because of the difference in vehicle size and weight. At night, investigators may also have to consider visibility, lighting, traffic flow, driver fatigue, and vehicle positioning.
Important evidence may include:
- Dashcam or highway camera footage
- Event data from the passenger vehicle and tractor-trailer
- Skid marks, debris fields, and final rest positions
- Truck driver logs and hours-of-service records
- Roadway lighting, weather, and traffic conditions
Because the cause has not yet been released, it is too early to assign fault. A careful investigation can help determine whether lane position, speed, fatigue, mechanical issues, or other factors contributed to the crash.
