A state trooper was taken to the hospital after his cruiser was hit on Interstate 91 southbound in Rocky Hill on Tuesday morning.
Police said the trooper was struck from behind while stopped to help a disabled vehicle on the shoulder near exit 23.
According to police, the offending car, a Chevrolet Cruze, was entering the highway from an on-ramp at exit 23 when it veered to the right.
The driver, Joanna Scanlon, of Rocky Hill, lost control and his car grazed the side of the police cruiser and "ricocheted" off, rolling over onto its driver's side.
Police said the trooper suffered head and face lacerations and injuries to his neck and back. He was taken by ambulance to Hartford Hospital for treatment.
Scanlon was also taken to the hospital for treatment of neck and back pain, according to police.
Both the police cruiser and Chevy Cruze were towed from the scene, police said.
Authorities are investigating the crash.
