Pennsylvania to Maryland: common questions
- Do the laws change when you drive from Pennsylvania to Maryland?
- Yes — 10 of the 13 categories LawLert tracks have a different status in Maryland than in Pennsylvania: firearms, fireworks, alcohol, knives, driving, gambling, burn bans, cannabis, taxes, drones. 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 Maryland if I'm coming from Pennsylvania?
- Maryland: Restricted — Illegal to manufacture, sell, or transfer a magazine over 10 rounds in-state. Treat 10 rounds as the practical limit. In Pennsylvania the same category is Permitted.
- What are the fireworks laws in Maryland if I'm coming from Pennsylvania?
- Maryland: Restricted — Only ground-based sparklers and fountains may be sold (where locally allowed); aerials/firecrackers aren't sold to consumers. In Pennsylvania the same category is Permitted.

- Maryland: Restricted — Maryland generally bars grocery chains from selling beer or wine — Talbot County is the main exception, plus a small number of grandfathered store licenses elsewhere. Plan on dedicated beer/wine/liquor stores. In Pennsylvania the same category is Conditional.
- Is my Pennsylvania concealed carry permit honored in Maryland?
- Permit reciprocity is decided separately from the firearms status shown on this page, so it is not answered here. LawLert publishes Maryland's recognition list, with the statute or agency page behind it, at lawlertapp.com/firearms/MD/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 Pennsylvania to Maryland 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.
