Full Breakdown

110(A) makes it unlawful to carry or possess an open container of fermented malt or alcoholic beverage on a city street, sidewalk, alley or other public place, on the grounds of any public or private school, college or university, or inside the passenger compartment of a vehicle located there; the same subsection separately bans actually consuming it in those places, and bars a vehicle operator from allowing an open container in the passenger compartment at all. 010. A narrow affirmative defense in subsection (B) covers a resealed, partially consumed bottle of wine: it must have originally held no more than 750 ml, be within 24 hours of purchase, come from a licensee that serves meals on-site (manufacturer, limited winery, beer-and-wine, hotel-and-restaurant, tavern, brew pub or vintner's restaurant licensees under subsection C), and the person must be carrying a dated purchase receipt and keep the bottle out of reach from the passenger compartment.

Subsection (D) sets the penalty: the municipal court may punish a conviction by a fine only, up to $500, with no term of imprisonment authorized under this specific section.

Violations & Fines

Longmont Police cite violators under § 10.16.110; the municipal court's authority is capped at a fine only, up to $500, since this section carries its own penalty rather than defaulting to the Title 1.12.010 general penalty (which allows up to 90 days in jail for offenses with no stated fine). The ban applies to the person drinking or holding the container and, separately, to the vehicle operator who lets an open container sit in the passenger compartment.

Frequently Asked Questions

Can I carry a resealed bottle of wine home from a restaurant in Longmont?
Yes, under a narrow affirmative defense in § 10.16.110(B). The bottle must be opened and resealed, hold no more than 750 ml originally, be within 24 hours of purchase, come from a qualifying licensee that serves meals, and you must carry the dated receipt and keep the bottle out of the vehicle's passenger compartment.
What's the penalty for an open container violation in Longmont?
Longmont Municipal Code § 10.16.110(D) limits the court to a fine only, up to $500. There's no jail exposure for this specific offense, unlike many other misdemeanor code violations that can carry up to 90 days under the Title 1.12.010 general penalty.
Does the open container ban apply on private property?
No. Section 10.16.110 covers streets, sidewalks, alleys and other public places, plus school grounds and vehicle passenger compartments in the city. It doesn't reach a private yard or backyard party, though other city nuisance or noise ordinances can still apply there.
