Waymo's collision report says: "On May 21, 2023 at 10:56 AM PT a Waymo Autonomous Vehicle ("Waymo AV") operating in San Francisco, California was in a collision involving a small dog on Toland Street at Toland Place.

The Waymo AV was travelling southwest on Toland Street when a small dog ran into the street in front of the Waymo AV. The Waymo AV then “contacted the dog”, which did not survive. At the time of the impact, the Waymo AV's Level 4 ADS was engaged in autonomous mode, and a test driver was present (in the driver's seating position). The Waymo AV sustained damage."

The collision was a block from Waymo's Toland Depot, a 120,000-square-foot warehouse that houses at least 50 autonomous cars. The incident is Waymo's first reported fatality.

Waymo said an investigation is ongoing, but the initial review confirmed that the system correctly identified the dog, which ran out from behind a parked vehicle. However, the car could not avoid contact.

“We send our sincere condolences to the dog's owner. The trust and safety of our communities is the most important thing to us, and we're continuing to look into this."
