The investigation is continuing into the four-vehicle wreck along Route 222 Thursday afternoon, East Cocalico Township police said.
Five people were injured in the crash.
Gregory Rymer, 33, of Red Lion, was in fair condition on Friday, a spokeswoman at Reading Hospital said. Lindsay Bricker, 23, of West Reading, was in good condition.
Rachel Hargenrater, 18, of Denver, was treated and released from Reading Hospital, the spokeswoman said.
Jessica Graybill, 24, of East Petersburg, and Zack Mell, 19, of Stevens, were treated and released from Lancaster General Hospital Thursday night.
Bricker tried to switch from the passing lane into the right lane and clipped a vehicle driven by Anthony Olinski, 30, of Philadelphia, police said.
Bricker lost control of her southbound vehicle, and it entered the median strip and rolled into the northbound lanes, striking cars driven by Rymer and Graybill head-on, police said.
Hargenrater and Mell were passengers in Graybill's vehicle.
Olinski was uninjured.
