At approximately 1:45 am, San Bernardino County Fire Department responded to a vehicle over the side in the 1800 block of South E Street. When arriving on scene, crews located a vehicle on it’s roof in the Santa Ana riverbed. The driver lost control of the vehicle, collided with the guard rail and crashed in the riverbed, under the overpass. No other occupants were in the vehicle and the driver was transported to a local hospital in unknown condition. It’s unclear if alcohol was a factor in the collision. San Bernardino PD is handling the investigation.
