Maryland State Police said it happened in the westbound lanes of Interstate 70 at Interstate 68 in Hancock. Fetterman was driving a Chevrolet Tahoe that struck the rear of a Chevrolet Impala "for unknown reasons," troopers said.
"Out of an abundance of caution, they were evaluated at a local hospital," a spokesperson said.
Fetterman was treated for a bruised shoulder and he and Giselle were discharged that afternoon, the spokesperson said.
A passenger in the Impala was also taken to the hospital, according to state police.
The Fettermans "are doing well and happy to be back in Braddock," the Senator's office said.
MSP said the crash remains under investigation.
