Rule 6102, 4 CCR 723-6, requires every motor carrier to pay an annual fee to the PUC for each vehicle it "owns, controls, operates, or manages" in Colorado. The proof of payment is a vehicle stamp issued by the Commission; each vehicle must bear that calendar year's stamp on its windshield. There are certain exceptions for those registered with Unified Carrier Registration (UCR).
The stamp fee for Calendar Year 2019 is $50.00 per stamp. Purchase of vehicle stamps and/or change of company address(es) may be done online. Alternatively, order stamps by mail using this form. Please allow three weeks for processing of mailed orders.
