South Dakota to Wyoming: common questions
- Do the laws change when you drive from South Dakota to Wyoming?
- Yes — 10 of the 13 categories LawLert tracks have a different status in Wyoming than in South Dakota: cannabis, hunting, alcohol, fireworks, firearms, drones, gambling, knives, taxes, driving. Each is listed on this page with its current status, the official source it came from, and the date it was last verified.

- Is my South Dakota concealed carry permit honored in Wyoming?
- Permit reciprocity is decided separately from the firearms status shown on this page, so it is not answered here. LawLert publishes Wyoming's recognition list, with the statute or agency page behind it, at lawlertapp.com/firearms/WY/reciprocity. Permitless carry, where a state allows it, is a different question again — it does not make an out-of-state permit valid.
