We spoke with Officer Olivera of the California Highway Patrol who tells us ... responding officers did not believe Trout was intoxicated at the scene of the crash and did NOT perform a field sobriety test.
According to the report, Trout was driving a black 2013 Mercedes on the 55 Freeway near Angels Stadium when he came upon slowed traffic and couldn't stop in time.
He tried to swerve but slammed into a a Chevrolet -- driven by a 27-year-old woman -- which careened into the rear of a 1994 GMC.
The GMC spun out of control until it slammed into a fence.
