Early this morning, at approximately 1:59 a.m., Contra Costa CHP was advised of a two-vehicle collision on I-680 southbound, just north of Treat Blvd in Walnut Creek. Upon emergency personnel and CHP arrival, it was determined a Nissan Sentra had collided with a dump truck, then subsequently rolled, collided with the concrete center wall, and sustained major damage.
Tragically the solo male driver of the Nissan (43 years old from Hayward) was pronounced deceased at the scene. The solo adult male driver of the dump truck was not injured. The Contra Costa County Sheriff’s Coroner’s Office will be handling the release of identity of the deceased male.
Our preliminary investigation indicates that the driver of the Nissan was traveling southbound on I-680 and for unknown reasons veered across the lanes (from right to left) and collided into the back of the dump truck. Then due to the impact, the Nissan rolled and collided into the concrete center wall and sustained major damage, partially trapping the driver inside. Once the Fire Department and emergency personnel arrived, the driver was extricated from the Nissan but unfortunately pronounced deceased on scene.
Through the investigation on scene, it appeared that the driver was not wearing his seatbelt. The solo male driver of the dump truck was not injured and remained on scene during the investigation.
Although alcohol bottles were located in the Nissan, it is unknown at this time if alcohol and/or drugs are a factor in this collision as it is still under investigation. If anyone witnessed this collision or the Nissan on I-680 prior to this crash, please contact Contra Costa CHP at (925) 646-4980. Thank you.
