Although Shia LaBeouf was arrested on suspicion of drunken driving, authorities say he was not at fault for a traffic wreck that left the Indiana Jones star with head and hand injuries over the weekend.

The other driver involved in the collision would be cited after blowing a red light early Sunday, Los Angeles County sheriff's spokesman Steve Whitmore said Tuesday.

LaBeouf's passenger, his Transformers: Revenge of the Fallen costar - and Entourage's Adrian Grenier's girlfriend - Isabel Lucas, was not seriously injured, according to the AP.

LaBoeuf is recovering from surgery on his hand. - Nina Hämmerling Smith
