Full Breakdown

Wyoming Statutes Title 35, Chapter 10, Article 2 governs fireworks definitions, sales restrictions, and county authority. Under W.S. 35-10-208, county commissioners may regulate or prohibit fireworks within unincorporated areas, and municipalities may impose stricter rules within city limits. However, House Bill 57 (2025) preempts local governments from prohibiting consumer fireworks use between 12:00 PM and 12:00 AM on July 4 unless a formal open-fire ban is in effect. Sales of fireworks not meeting federal CPSC standards under 16 C.F.R. Part 1507 are universally prohibited statewide regardless of locality.

Violations & Penalties

Violating state fireworks restrictions is a misdemeanor. Illegal sale or possession of non-compliant fireworks may result in fines, seizure, and disposal under W.S. 35-10-206.
