A self-driving car being tested by Google has collided with a public bus in California, an accident report revealed.
The incident happened on Valentine's Day, according to a report submitted to the Department of Motor Vehicles (DMV).
The report was written by Google, which has been testing two dozen Lexus SUVs outfitted with sensors and cameras near the tech firm's Silicon Valley headquarters.
Google wrote that its car was trying to get around some sandbags on a street when it struck the right side of the bus.
The car was rolling at 2mph, the bus at 15mph.
No one was injured.
Google said its car's safety driver thought the bus would yield.
The report does not address fault. A DMV spokeswoman said the agency hoped to speak with Google about what went wrong.
A Google spokesman did not have immediate comment.
