Wyoming to Colorado: common questions
- Do the laws change when you drive from Wyoming to Colorado?
- Yes — 10 of the 13 categories LawLert tracks have a different status in Colorado than in Wyoming: fireworks, driving, firearms, knives, boating, hunting, cannabis, drones, gambling, taxes. Each is listed on this page with its current status, the official source it came from, and the date it was last verified.
- What are the fireworks laws in Colorado if I'm coming from Wyoming?
- Colorado: Restricted — Ground and novelty only: fountains, wheels, ground spinners, sparklers, snakes, novelties. Firecrackers, bottle rockets, Roman candles, and any aerial/exploding device are prohibited statewide. In Wyoming the same category is Permitted.
- What are the driving laws in Colorado if I'm coming from Wyoming?
- Colorado: Restricted — Colorado bans handheld mobile device use for all drivers and requires hands-free use instead. The ban took effect in 2025 (SB24-065, Colo. Rev. Stat. 42-4-239). In Wyoming the same category is Conditional.

- Colorado: Conditional — Permit (CHP) required; shall-issue via county sheriffs. Minimum age 21. Not constitutional carry. In Wyoming the same category is Permitted.
- Is my Wyoming concealed carry permit honored in Colorado?
- Permit reciprocity is decided separately from the firearms status shown on this page, so it is not answered here. LawLert publishes Colorado's recognition list, with the statute or agency page behind it, at lawlertapp.com/firearms/CO/reciprocity. Permitless carry, where a state allows it, is a different question again — it does not make an out-of-state permit valid.
- How current is this Wyoming to Colorado comparison?
- Every rule on this page stores the date it was last checked against its source; the oldest on this comparison is 2026-05-31. LawLert carries 6,693 rules, each with a source URL, and publishes a log of every correction it has made at lawlertapp.com/how-we-verify.
