Authorities said around 12:10 p.m. a call came in regarding a vehicle on the side of the road on the eastbound 126 Freeway.
Ford, who was either leaving from or going to the Santa Paula Airport, helped the victim, authorities said. The victim suffered minor injuries and was taken to a hospital for an evaluation.
TMZ published pictures Sunday of Ford standing by the car on the side of a hill and talking with police.
A representative for the actor did not have a comment.
