Commercial vehicles that weigh less than 18,000 lbs, Diesel-powered commercial vehicles that weigh 8,501 pounds or more require an additional fee.
Okay. I'd also like to know if a full 2-year refund is available if the registration sticker is never used. Will I receive this refund as soon as I return my plates?
When you surrender your plates, your Receipt FS-6 T indicates if you are eligible to receive a refund.  If you are eligible and you do not request a transfer receipt, the refund will be processed automatically and you will receive it in the mail in several weeks.
What was the form that would indicate if I am eligible for the refund?
