Key questions for this type of case
A rideshare crash file should preserve the driver's app status, trip receipt, pickup and drop-off data, platform communications, personal and commercial insurance information, and the ordinary collision record. California CPUC materials describe different coverage periods, but an attorney must evaluate which policy and legal issues apply to the actual facts. Save screenshots in their original form, note when the trip was accepted and completed, and identify every insurer or platform representative who communicated about the collision.
