desks for this cover

MDT OS/OW
Montana oversize is MDT. Wind and mill moves still need Montana dimensions on a Montana permit.
Seasonal weights
Seasonal weights on Montana highways are MDT, not 387.9.
Montana DOJ / MDT
IRP and IFTA sit with the state motor vehicle desk. Interstate BI&PD is L&I.
Billings cells
A load-board cell is not the census telephone. Call the number on SAFER.

seasonal weights are mdt

Call the census telephone. A Billings or Missoula cell is not the office until it reaches the legal person on L&I. Match Inc versus LLC on the rate con.

Wind and mill moves still need Montana dimensions on a Montana permit. Wyoming WYDOT or North Dakota NDDOT paper does not cover Montana miles. Seasonal weights are MDT, not 387.9.

Mountain weather holds are a cover call. They are not an Unsatisfactory rating. If they swap trucks because of a pass, confirm you are still on the same MC. Re-open L&I the morning of pickup.

FMCSA vs Montana

An Active FMCSA property MC is interstate operating authority. It is not a Montana oversize permit, not IRP, not IFTA, and not intrastate authority. If this load never leaves Montana, ask whether they have the state credential — and still match legal name on L&I if an MC is on the rate con.

As of September 2026, table 1 to 49 CFR 387.9 still lists $750,000, $1,000,000, and $5,000,000. The January 16, 2026 change is broker/freight-forwarder BMC-84/85 at $75,000 — your house, not the truck. The March 2026 FMCSA notice still says: do not buy or sell a USDOT or MC outside a real corporate deal.

UCR is a separate annual filing. It is not BMC-91 and not a MT OS/OW permit. Confirm UCR on the national UCR site if your process requires it. Then come back to L&I for the truck.

Montana permits and credentials

Montana OS/OW is MDT. Wind and mill moves still need Montana dimensions on a Montana permit.

Montana IRP/IFTA is the state motor vehicle desk. Interstate BI&PD is L&I.

Attach the MDT permit for Montana miles and current seasonal postings. Neighbor-state paper does not cover them.

first-touch in Montana

  • Do legal name, USDOT, and MC on the rate con match L&I?
  • Does the census telephone reach this motor carrier, not a Billings cell?
  • If oversize, is an MDT permit in hand for these Montana miles and these seasonal postings?
  • If they want to swap trucks because of weather, is it still the same MC?
  • If the load continues into Wyoming or North Dakota, whose permit covers those miles?

fail closed

  • Montana miles covered on Wyoming or North Dakota paper only.
  • Census phone is a Billings cell that will not state the DOT.
  • Oversize Montana miles with no MDT permit.
  • MC swapped in weather without a new L&I pull.

direct answers

Can I cover Montana miles on a Wyoming permit only?
No. Wyoming paper does not cover Montana miles. Confirm L&I, then MDT.
Are seasonal Montana weights a 387.9 row?
No. Seasonal weights are MDT. Federal BI&PD floors stay on L&I. Confirm both if both apply.
Does a Billings cell replace the census telephone?
No. Call the number on SAFER. Extra mill phones can conference the office.
