   A person less than 21 years of age shall not knowingly transport or possess, in a motor vehicle, alcoholic liquor unless the person is employed by a licensee under state law, a common carrier designated by the Liquor Control Commission pursuant to state law, the Liquor Control Commission, or an agent of the Liquor Control Commission, and is transporting or having the alcoholic liquor in a motor vehicle under the person’s control during regular working hours in the course of the person’s employment. This section does not prevent a person less than 21 years of age from knowingly transporting alcoholic liquor in a motor vehicle if a person at least 21 years of age is present inside the motor vehicle. A person who violates this section is guilty of a violation of this code. As part of the sentence, the person may be ordered to perform community service and undergo substance abuse screening and assessment at his or her own expense as described in § 90.05(A).
