A fatal traffic collision occurred on SR-154 eastbound, just west of San Antonio Creek Road at approximately 5:30 a.m. The collision involved a Toyota Sedan, which struck the embankment adjacent the dirt shoulder north of the roadway. California Highway Patrol Officers, Santa Barbara Sheriff’s Deputies, and Santa Barbara County Fire Department personnel responded to the scene. A Santa Barbara County Fire Paramedic confirmed the driver, the only occupant in the Toyota, was deceased on scene. The vehicle was facing westbound in the eastbound lanes. Both lanes of SR-154 were closed for approximately three hours to investigate the collision. The name of the occupant cannot be released because notifications have not been made to the family. This will be an ongoing investigation.
