How this checker works
Every rule in this tool was verified against the primary source — the actual eCFR section, state statute, or state agency page — and carries its citation and verification date. We show only verified rules: if we haven't confirmed your state yet, we say so plainly instead of guessing. It's a decal list from a decal shop, not legal advice — for the final word, the result includes your state agency's contact info.
