N.C. Gen. Stat. § 119-56
A person shall not hold himself out or commence operation as a dealer without first having registered as provided in this section. A dealer shall register with the Commissioner on a form to be furnished by the Commissioner. Such form shall give the name and address of the dealer, the place or places of and type or types of business of such dealer, and such other pertinent information as the Commissioner may deem necessary. Verification of the insurance coverage required by this section or of proof of alternative means of financial responsibility permitted by this section shall be submitted to the Commissioner as a condition of the issuance of any registration or renewal of such registration.
There shall be two classes of dealers:
A Class A dealer shall obtain and maintain general liability insurance, including product liability, of one million dollars ($1,000,000) and motor vehicle liability insurance of one million dollars ($1,000,000) combined single limit. A Class B dealer shall obtain and maintain general liability insurance, including product liability, of one hundred thousand dollars ($100,000). Verification of said insurance coverage shall be made in a manner satisfactory to the Commissioner. The Commissioner may from time to time request in writing that a dealer provide within 10 days of such request verification of said insurance coverage or proof of alternative means of financial responsibility. In lieu of insurance, the dealer may file and maintain a bond, certificate of deposit or irrevocable letter of credit in a form satisfactory to the Commissioner which provides protection for the public in the same amounts and to the same extent as said insurance.
The provisions of this section shall not apply to a dealer who retails liquefied petroleum gas in containers of less than 50 pounds water capacity and which retailing does not involve the filling or transportation of such containers.
