FATALITY MOTORCYCLE CRASH on SR-4 in Discovery Bay
Today at approximately 1:45pm, Contra Costa CHP was advised of a two vehicle collision involving a motorcyclist on SR-4 eastbound, just west of Discovery Bay Bridge (Old River Bridge) in Discovery Bay. Upon emergency personnel and CHP arrival, a 2015 Yamaha motorcycle had collided with a 2012 Volvo Big Rig after passing another vehicle. The male rider of the Yamaha (17yr old male from Stockton) was subsequently killed as a result of the collision. The adult male driver of the Volvo was not injured. The Contra Costa County Sheriff’s Coroners Office will be handling the release of identity of the deceased motorcyclist.
Alcohol and/or drugs do not appear to be a factor in this collision but it is still under investigation. If anyone witnessed this collision or the vehicle just prior to the collision and you haven’t already spoken with CHP, please contact Contra Costa CHP at (925)646-4980. Thank you.
