Arizona to Colorado: common questions
- Do the laws change when you drive from Arizona to Colorado?
- Yes — 8 of the 13 categories LawLert tracks have a different status in Colorado than in Arizona: firearms, knives, alcohol, boating, hunting, driving, drones, 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 firearms laws in Colorado if I'm coming from Arizona?
- Colorado: Conditional — Permit (CHP) required; shall-issue via county sheriffs. Minimum age 21. Not constitutional carry. In Arizona the same category is Permitted.
- What are the knives laws in Colorado if I'm coming from Arizona?
- Colorado: Conditional — Carrying a knife concealed is a misdemeanor where the blade exceeds 3.5 inches (C.R.S. 18-12-105; the 3.5-inch 'knife' definition is in 18-12-101). Carry in your home, place of business, or private vehicle is exempt. In Arizona the same category is Permitted.

- Is my Arizona 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 Arizona to Colorado comparison?
- Every rule on this page stores the date it was last checked against its source; the oldest on this comparison is 2026-06-18. 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.
