Summary

Naperville bans drinking alcoholic beverages on any street, highway, or public place, or in or about a vehicle in public, unless the City Council specifically authorizes it.

It shall be unlawful for any person to drink any alcoholic beverages on any street, highway or public place or in or about any motor vehicle upon any street, highway or public place in the City, unless specifically authorized by the City Council and except as provided in 625 Illinois Compiled Statutes 5/11-502 of the Illinois Vehicle Code adopted by reference pursuant to Section 11-1-1 of the Naperville Municipal Code.

(Ord. No. 92-56, 4-7-1992; Ord. No. 11-126, § 1, 9-6-2011)

Editor's note— Ord. No. 11-126, § 1, adopted September 6, 2011, repealed the former Section 10-2-2-1 in its entirety, which pertained to intoxication and derived from Ord. No. 73-81, adopted October 22, 1973. Subsequently, the former Sections 10-2-2-2 and 10-2-2-3 were redesignated as Sections 10-2-2-1 and 10-2-2-2. The historical notation has been preserved for reference purposes.
