Fireworks Buying Age in states bordering Idaho

The same rule in each neighboring state LawLert has verified, from that state’s own official source.

MontanaInfo
Montana sets no statewide minimum purchase age in statute, so expect retailers to check your age. Approved stands and retail stores sell fireworks only during the legal sale windows — never by mail order, and never within 300 feet of a hospital or church.

NevadaInfo
Nevada sets no statewide purchase age — your county's ordinance sets it. Seasonal "safe and sane" stands, such as those in Clark County, sell only during the legal window, and Clark County bars bringing fireworks in from other states or counties.

UtahInfo
Utah has no statewide minimum-age statute in its fireworks act, though retailers and localities may limit sales to adults. Licensed retailers sell them seasonally, typically in late June and December. Aerials that are legal in Utah may still be banned in restricted areas, regardless of where they were bought.

WyomingInfo
Wyoming's fireworks statutes (W.S. 35-10-201 through 35-10-208) set no statewide minimum age to buy or use consumer fireworks. Any age condition comes from county resolutions or city ordinances, which may also prohibit sale or use outright — and a local ban makes use or possession illegal regardless of where the fireworks were purchased. Violations are a misdemeanor: fine up to $750, up to 60 days, or both.
