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, you will want to be sure that your information on the FMCSA Motor Carrier Identification Report (Form MCS150) is current. We reference this information when we set up your account. Discrepancies between the information on your application and what shows up in the federal system will slow down the approval process.

If your business has changed its Company Name, USDOT number or TIN (Tax Identification number), please make sure to update your Form MCS150. After this has been completed, please notify MCS at 406-444-7262 so that we can keep your permitting account information updated.
