One Plate, and Nothing Over It
ORC 4503.21 — the rear plate, since July 2020, and the cover that makes it a ticket
For most of the state's history a car needed two plates, and a good number of the cars on the road still carry a front one because the holes were there. Since the first of July 2020 the requirement is one, at the rear, and what the section now spends most of its words on is not how many plates but whether the one you have can actually be read.

One plate, on the rear, in plain view. No person who is the owner or operator of a motor vehicle fails to display in plain view on the rear of the motor vehicle a license plate displaying the distinctive number and registration mark assigned to it, including any county identification sticker and any validation sticker when required. A commercial tractor displays its plate on the front instead, which is the one exception the section makes.
Nothing may cover it, and it may not swing. The plate is securely fastened so as not to swing, and is not covered by any material that obstructs its visibility. A tinted or smoked cover, a frame that sits over the sticker, or a hitch that hides the numbers are each a way of failing this sentence, and none of them is cured by the plate being present.
A temporary registration is displayed in plain view from the rear of the vehicle, either in the rear window or on an external rear surface, and no person covers it with any material that obstructs its visibility. The same rule reaches the paper tag as reaches the metal one.
The section is strict liability. The offenses under the display division are strict liability offenses, and the section of the criminal code that would otherwise read a mental state into a statute that names none does not apply. Not knowing the cover was too dark, or that the frame covered the sticker, is not a defense the section recognizes.
The plate also has to be lit. A tail light or a separate lamp illuminates the rear plate with a white light and renders it legible from fifty feet to the rear, wired to come on whenever the headlights or auxiliary driving lights are on. That is a separate section with its own minor misdemeanor, and a working tail light does not answer for a dead plate lamp.

Registration and validation stickers, historical vehicle plates, dealer and manufacturer plates, and the rules for trailers and motorcycles are each their own part of the licensing chapter and are not set out here. Whether a particular frame or cover obstructs visibility is a question of fact in a particular case, and what a citation carries in a particular court is a question for a licensed Ohio attorney.
