What an expired-registration ticket costs in Louisiana

No Louisiana statute or OMV page found gives a driving grace period for an expired plate. The registration law makes it an offense to operate a vehicle that is not registered or that does not display the number plates assigned to it for the current year (La. R.S. 47:536(A)(1)), and a registration not renewed by its renewal date becomes delinquent (R.S. 47:508(C)). Local schedules may list the charge under R.S. 47:508, the renewal-date section: the St. Charles Parish Sheriff’s Office schedule calls it “license plate, expired”. Under the registration law the penalty is a fine of up to $100, up to 30 days in jail, or both (R.S. 47:536(B); R.S. 47:537 sets the same ceiling for any violation of the chapter that has no penalty of its own). If the ticket cites Title 32 instead, which requires a vehicle to be registered with its license tax paid (R.S. 32:51) and its plate displayed during the current registration year (R.S. 32:53(A)(2)), a first violation carries a fine of up to $175, up to 30 days, or both (R.S. 32:57(A)(1)). No statewide schedule fixes the amount: the judges of each judicial district except Orleans may, with the district attorney’s consent, adopt a parishwide schedule of fines, penalties and costs within those limits (R.S. 32:641), and city and mayor’s courts publish their own. Court costs can be most of the bill. Examples from official schedules checked in October 2026: Bossier City Court (schedule dated January 1, 2026) charges a $50 fine plus costs, $162 total, for an expired plate or expired registration; Baton Rouge City Court’s ticket page lists expired license plate in a group whose total fine, costs and charges are $119 per violation, under a heading that reads $124; the St. Charles Parish Sheriff’s Office schedule (updated April 15, 2026) lists $179.50 for R.S. 47:508, license plate expired, in its fine amount column with no separate cost figure; and Covington Mayor’s Court lists $195 to pay instead of appearing (page last updated November 2023). Separately from the ticket, renewing after your renewal date brings a statutory penalty plus interest (R.S. 47:508(C)), and OMV’s online-renewal FAQ says the renewal total includes a late fee if your registration is expired. The penalty for failing to apply and pay a registration fee under the vehicle registration license tax chapter is $3 or an amount computed as otherwise provided in R.S. 47:1602, whichever is greater (R.S. 47:1602(C)). The rest of that section computes penalties on late tax returns and payments as 5% of the tax for each 30 days, up to 25%, but neither the statute nor any OMV page found says how that computation applies to a registration renewal, so this page states only the $3 floor. Interest runs under R.S. 47:1601 from the payment date until the tax is paid, at three percentage points above the rate set under R.S. 9:3500(B)(1), never more than 1.25% a month. Passenger plates cost 0.1% of the vehicle’s value per year with a $10,000 minimum value, sold in two-year increments (minimum $20), per OMV’s fee page.
