Registration Renewal 

Renewal notices for your vehicle registration are mailed approximately 30 days before the registration expires. The accompanying form may be returned by mail with the correct fee, insurance information and personal property tax receipt. This transaction may also be completed at any DMV Regional Offices. County sheriff's offices can renew passenger vehicles (Class A) and motorcycle registrations (Class G).

It is the vehicle owner's responsibility to know when their plates expire, the notice is just sent as a reminder.
