First:
Pay the other-persons' medical & property damages
(unless they were completely-liable/responsible for the-accident, & NOT-you).
Act as a BENEVOLET-"insurance-adjuster",
request multiple-repair-quotations,
but ensure other-parties are "happy" & bills paid.
Second (depending on your-jurisdiction/state),
You PROBABLY need MANDATORY-"SR-22"-bond/liability-insurance.
Third,
You PROBABLY need to promptly report the accident to your local-jurisdiction/state-BMV/DMV-authorities.
