A person may renew a noncommercial vehicle registration anytime less than ninety days prior to the vehicle's registration expiration date. Any person who renews a noncommercial vehicle registration after the date of expiration shall pay the full year's fee required by this chapter to license the vehicle until the appropriate month assigned for renewal by § 32-5-2.2. However, this requirement to pay the full year's fee does not apply to noncommercial motor vehicles licensed pursuant to § 32-5-6.3 or 32-5-6.4.
