According to the California Highway Patrol (CHP), the collision took place on the northbound lanes of Highway 101, south of East Washington Street. The CHP investigators concluded that the woman from Cotati was driving a Honda CR-V behind a Range Rover. The Range Rover was moving at a slow speed due to stop-and-go traffic, while the Honda was traveling at an unsafe speed given the traffic conditions. As a result, the Honda rammed into the back of the Range Rover. The driver of the Honda sustained major injuries and was rushed to the hospital
