(a)

Alcoholic liquor shall not be sold or furnished to a person unless the person has attained 21 years of age. A person who knowingly sells or furnishes alcoholic liquor to a person less than 21 years of age, or who fails to make diligent inquiry as to whether the person is less than 21 years of age, shall be deemed guilty of a violation of this chapter and punished as provided in section 1-13. A suitable sign which describes this section and the penalties for violating this section shall be posted in a conspicuous place in each room where alcoholic liquors are sold. The sign shall be approved and furnished by the state liquor control commission.

(b)

In an action for violation of this section, proof that the defendant, or the defendant's agent or employee, demanded and was shown, before furnishing alcoholic liquor to a person under 21 years of age, a motor vehicle operator's license or registration certificate issued by the federal selective service, or other bona fide documentary evidence of the age and identity of that person, shall be a defense to an action under this section.
