Police said Jay Good and his wife, D. Jean Good, were returning to Lititz with their daughter, Jacy Good, following her graduation from Muhlenberg College in Allentown when their station wagon slammed into a dairy truck.
The parents, both 58, were pronounced dead at the scene.
Jacy Good, 21, who graduated magna cum laude and Phi Beta Kappa, underwent surgery at Reading Hospital and was listed in critical condition on Monday.
The Good family's church, Bethany U.C.C. at 140 East Main Street in Ephrata, will hold a prayer service tonight at 7:00.
A dual major in German and international studies, she planned to work for Habitat for Humanity in Brooklyn, N.Y., through the AmeriCorps program.
"She is a great, great kid," Muhlenberg spokesman Mike Bruckner said. "This is breaking the whole community up."
Her mother, Jean Good, worked as a language arts teacher at Ephrata Middle School.
Mrs. Good "was one of our finest and most dedicated educators.
... Jean will be deeply missed," said Superintendent Gerald Rosati.
Jay Good worked at a foundry in Wrightsville.
The Goods' car had been loaded with Jacy Good's personal belongings, including a sofa, police said.
Police identified the driver of the tractor-trailer as Joseph Leonardo Jr., 44, of Hamburg, and the driver of the minivan as Todd M. Whitt, 18, of Muhlenberg Township. Leonardo, Whitt and two teenagers in the minivan were treated in Reading Hospital, officials said.
Police said Leonardo, who was traveling northbound in a Clover Farms Dairy truck, swerved at an intersection to avoid the westbound minivan, which had entered the truck's path. The truck hit the minivan and then slammed head-on into the Goods' car.
Police said the crash occurred at highway speeds - unusual for that stretch of 222, where traffic is usually at a crawl due to a bottleneck.
"Traffic was flowing rather free at the time of the accident," said Northern Berks Regional police chief Scott Eaken.
No charges have been filed. Eaken said he expects an investigation to take about a week.
