A reminder to check your route

When you begin issuing your own permits, it is important to remember your responsibility to check construction reports and load-speed restrictions to verify that the route you plan to take does not have unanticipated restrictions.

Is your federal information up-to-date?

To avoid unnecessary delays with MCS, please make sure that your information on the FMCSA Motor Carrier Unified Registration System is current. MCS does reference this information when a new account is set-up; and/or periodically as needed. Discrepancies between information provided to MCS and what shows up in the federal system, will slow down MCS processes.

If your business has changed its Company Name, USDOT number, TIN (Tax Identification number), and/or mailing or physical address, please make sure to update your forms on the FMCSA site. After this has been completed, please notify MCS at 406-444-6130 so that MCS can keep your account information updated on our MCS systems.


For permitting forms, please see our forms page.


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.
