On Thursday evening, January 02, 2020 at approximately 4:47 PM, it was reported to 9-1-1 a motor vehicle collision had occurred fronting the Bon Air Shopping Center on westbound Sir Francis Drake Boulevard at the intersection of La Questa Drive in Greenbrae.  Upon preliminary investigation it was learned the driver and sole occupant of a Toyota pick-up truck was travelling at a high rate of speed westbound on Sir Francis Drake Boulevard with a fully marked California Highway Patrol vehicle trailing behind, and attempting to have the driver stop his vehicle, who had failed to yield.  The aforementioned pick-up truck continued westbound and failed to stop at a red traffic control signal and collided with a full sized GMC pick-up truck exiting from the shopping center, onto La Questa Drive travelling through a green traffic control signal.  The Toyota pick-up truck then struck an overhead light standard-utility pole and other fixed objects finally coming to rest in the roadway west of the intersection.  Both vehicles sustained significant damage during the collision.   The driver of the Toyota pick-up truck sustained significant traumatic injuries as a result of the collision and was discovered unresponsive, unconscious and lifeless inside his vehicle by First Responders.  Unfortunately due to his injuries, the driver of the Toyota pick-up truck was pronounced deceased on the scene at 4:54 PM.  The driver of the GMC pick-up truck was not injured.

For reasons which remain under investigation, reportedly the driver of the Toyota pick-up truck had been involved in an altercation with another motorist in San Rafael, which was on-viewed by the California Highway Patrol.  Officers attempted to contact the subject, who chose to flee from the scene and / or contact.  He failed to yield to the Officers eventually leading up to the collision.
