I did when I first registered it in Colorado in 2009.  Since then, regulations have changed somewhat and vehicles registered 1975 or before that are not driven more than 4,500 miles per year (affidavit signed by owner at registration time) are generally exempt.  Registration is good for five years.  If not registered as a collector vehicle, testing is annually (two-speed idle test and check for originally-installed emissions equipment).  1976 with collector plates get idle-tested every five years.  Without collector plates, generally everything gets tested annually, although 1981 and older is the two-speed idle test and equipment check.

Also depends on county (or part of county) of registration; some areas of the state are exempt altogether.
