Every person who drinks any intoxicating liquor in any public conveyance, except in a compartment or place where sold or served under the authority of a license lawfully issued, is guilty of a misdemeanor. With respect to a public conveyance that is commercially chartered for group use, and with respect to a for-hire vehicle licensed under city, county or state law, this section applies only to the driver of the vehicle. (Ord. 1627 § 1, 1996).
