The SUV was traveling eastbound in the left lane near mile marker 32.1 in Windsor Township (Berks County) when it swerved into the right lane, and rear-ended a tractor-trailer around 10:20 a.m., according to Pennsylvania State Police.
The SUV then flipped onto its driver's side and skidded until it came to a stop against the center median, state police said.
The 37-year-old male SUV driver from Florida was taken to Lehigh Valley Hospital-Cedar Crest with unknown injuries, as were a 23-year-old female passenger, a three-year-old female passenger, and a one-year-old male passenger, state police said.
The 64-year-old male tractor-trailer driver was uninjured, according to police.
Shoemakersville Fire Department assisted Pennsylvania State Police at the scene.
