2015

February​: A Google Lexus model AV was travelling northbound on El Camino Real in autonomous mode when another vehicle travelling westbound on View Street failed to come to a stop at the stop sign at the intersection of El Camino and View Street. The other vehicle rolled through the stop sign and struck the right rear quarter panel and right rear wheel of the Google AV. Prior to the collision, the Google AV's autonomous technology began applying the brakes in response to its detection of the other vehicle's speed and trajectory. Just before the collision, the driver of the Google AV disengaged autonomous mode and took manual control of the vehicle in response to the application of the brakes by the Google AV's autonomous technology. The Google AV was in manual mode. No injuries were reported at the scene. The Google AV sustained some damage.

April:​A Google Lexus model AV was involved in an accident in Mountain View while travelling northbound on Castro St and making a right turn onto El Camino eastbound. The car was operating in autonomous mode at the time of the accident. The Google AV was travelling northbound in the rightmost lane of Castro St and came to a complete stop for a red light at the intersection of Castro St and El Camino Real. The Google AV then proceeded to make a right turn on red by creeping forward to obtain a better field of view of cross traffic on El Camino Real approaching from the left. While creeping forward, the Google AV detected a vehicle approaching eastbound on El Camino Real and came to a stop in order to yield to the approaching vehicle. The Google AV was just starting to move (<1 MPH) when the vehicle following immediately behind it, which was also attempting to make a right turn onto El Camino Real, failed to brake sufficiently and struck the Google AV's bumper at approximately 5 MPH. All occupants of both vehicles involved were uninjured in the collision. The Google AV sustained minimal body damage and the other vehicle sustained no visible body damage.

April: ​A Google Lexus model AV was stopped for a red light at an intersection of California Street and Shoreline Boulevard in Mountain View when another vehicle tried to pass from behind on the right side of the Google AV. The driver of the other vehicle slightly brushed one of the sensors on the Lexus AV with its driver side mirror. The Google AV was in autonomous mode. No injuries were reported at the scene, and there was no damage to either the sensor or either vehicles.
