Most insurance companies today offer rideshare insurance so you'd just need to speak to your auto insurance company and ask them if they have rideshare insurance which I'm sure they do.
Although the few insurance companies that I know of that offer rideshare insurance for sure are Geico, Allstate, State Farm, Progressive Insurance, and USAA (United Services Automobile Association)
You'll have to pay extra to have rideshare insurance but you do have to have the rideshare insurance to be able to signup to drive for Uber and Lyft.
