Will Ferrell has been discharged from hospital following a two-car crash south of Los Angeles on Thursday night.
The actor was one of three passengers in a chauffeur-driven SUV which was hit by another vehicle, his manager told US entertainment trade website Deadline. The freeway crash was first reported by showbusiness website TMZ.
California Highway Patrol Sgt Richard Peacock said the crash took place before 11:00pm (US time) on the Interstate 5 in Mission Viejo in Orange County, California.
Sgt Peacock said Ferrell's vehicle was hit by another vehicle that had veered into its lane. The vehicle in which Ferrell was travelling then hit the median strip and overturned.
A statement from Ferrell's talent agency, UTA, said: "While travelling back to Los Angeles after hosting a voter registration event in San Diego, a car carrying Will Ferrell and three of his colleagues was struck on the freeway by another vehicle.
"Will and his colleague, Andrew Steele, were unhurt and have been released from an Orange County hospital. Will's longtime driver, Mark Thompson, and his other colleague Carolina Barlow, remain hospitalised in stable condition.
"Will is staying close by as his friends are being treated, and has expressed his deep gratitude to the first responders who were immediately at the scene and to the hospital team that took such great care of them. He's also grateful for all the well wishes he and his friends are receiving."
The driver of the other car was reported to be unhurt.
