YOM tags can be registered two ways. The way Bill and I have ours registered is Antique Registration. We are restricted by Sec. 504.502 to "(3) is used exclusively for exhibitions, club activities, parades,
and other functions of public interest and is not used for regular
transportation; and
(4) does not carry advertising."
They can also be registered by Classic Registration (Section 504.501). With this you can drive it to work or any other daily use and requires yearly renewal and inspections. For this you pay regular registration fees.
