The proof of payment is a vehicle stamp issued by the Commission. Vehicle must bear that calendar year's stamp on its windshield. There are certain exceptions for those registered with the Unified Carrier Registration (UCR) program.
The stamp fee for Calendar Year 2020 and for Calendar Year 2021 is $50.00 per stamp. Purchase of vehicle stamps and/or change of company address(es) may be done online.
