Oklahoma allows YOM on cars/trucks older than 25 years of age. The state went to the tag stickers in 1979, so a vehicle newer than that won't be able to run a YOM since technically, there isn't one from that point forward,
The number can only be run if the number is not currently in use on any other OK-registered vehicle, regardless of class/type. It costs $21.00 per year, plus the cost of normal registration (also $21.00). The regular tag must be kept inside the vehicle. A windshield sticker is issued at renewal that tells the cops your tag is a legal registration. Without that, you get a ticket for no tag! The YOM plate is treated the same as a personalized tag in terms of fees and carrying your regular tag. A tag can be restored and used, but it's supposed to be in the correct colors for that year.
