If you do not license under IRP and register your truck at the Montana county in which you live, you may pay Gross Vehicle Weight (GVW) fees at the county when you license. Alternatively, these fees may be purchased from the Motor Carrier Services office in Helena, at one of our weigh stations, or from any MCS patrol officer.

You can pay GVW fees for a single month, multiple months, or a full year if you apply for a annual-term permit. These options are listed on the GVW Fees Chart and GVW Farm Fees Chart.


For more information about permits, please call Motor Carrier Services in Helena at 406-444-7262 or consult the Trucker's Handbook.
