Reports say another driver had to be extricated from her car, but Trout was uninjured.
The collision happened around 9 p.m. Wednesday near the McFadden exit of the 55 Freeway in Tustin, Calif.
A witness said it appeared Trout was trying to avoid another crash on the freeway when the brakes on his Mercedes locked up and he struck another vehicle.
A woman driver in the other car was trapped and had to be extricated by rescue crews. She was transported to a local hospital.
Trout was seen walking around and talking to firefighters after the crash.
Angels general manager Billy Eppler said in a statement he's spoken to Trout and "he feels fine."
Eppler said Trout was at home and is planning to travel with the club Thursday to Seattle.
Trout was born in Vineland, N.J. and is a 2009 graduate of Millville Senior High School in Millville, New Jersey.
In 2014, Trout was unanimously selected as the American League MVP, becoming the sixth player in MLB history to win both the regular season MVP and the All-Star Game MVP in the same season.
He is batting .319 with 25 homers and 21 stolen bases this season.
