As an independent photojournalist, you face many risks your homeowners, auto or health insurance won't cover. It's folly to attempt our jobs without camera insurance. But your business has other potential liabilities, from the tripod that trips up the UPS guy, to errors and omissions, libel and more. Review your coverage often. Keep good records. In addition, you should have disability insurance in case something happens to prevent you from working. If you have an employee--in many states this includes freelance assistants--you need to purchase workers compensation insurance. If that employee drives your vehicle, you'll need still more insurance. Be careful out there.
