Illegal Fireworks
Any devices or components that, when used or ignited, project or disburse any metal, glass, or brittle plastic fragments. Cherry bombs, roman candles, firecrackers, bottle rockets, shells and rockets, M-80s and M-100s, and helicopters are all examples of illegal fireworks.
A good rule of thumb: anything that explodes or leaves the ground is most likely illegal in Colorado.
Permissible Fireworks (Unincorporated Jeffco)
Cylindrical or cone fountains, wheels and ground spinners, illuminating torches and colored fire, dipped sticks and sparklers, toy propellant or toy smoke devices, trick noisemakers, and snake or glow worms are all permissible when a fire restriction or ban is not in effect.
For those that live in incorporated Jefferson County, please visit your city's website for policies on fireworks.
