Uber declined to comment on the case Monday. The company pointed to an earlier statement that said the incident did not involve a vehicle or driver performing a trip on Uber's system. Uber has since deactivated Muzzaraf's account.
Graham Archer, the attorney for Muzzaraf, said his client "was working for Uber" at the time of the accident. He had previously dropped off a fare and was waiting for another request at the time of the accident, he said.
Christopher Dolan, the plaintiffs' attorney, could not be immediately reached for further comment.
The California Public Utilities Commission decided last September to classify companies like Uber as "transportation network companies," requiring that they fulfill various requirements to keep drivers and passengers safe.
The new rules said that the companies should require a minimum of US$1 million per-incident insurance coverage, but only for vehicles in transit to or during a trip.
