WBRE-TV said that the incident occurred at 6:30 p.m. local time (22:30 GMT) on Saturday outside the Intoxicology Department restaurant.
Natalie Buyny, Spokeswoman for Geisinger Medical Center told NBC in a statement that there were 13 injured people following the crash.
"As of 8:30 p.m. on Saturday, Aug. 13, Geisinger is providing care for 13 patients from an incident in Berwick. Staff is assessing and triaging patients for appropriate care," Buyny said.
Berwick residents gathered on Saturday for an event to raise funds for the families of the victims of a house fire that killed seven adults and three children last week in neighboring Nescopeck.
