Verified Oct 22, 2026 against FMCSA Company Census File (data.transportation.gov)

Knife River Corporation-Northwest (USDOT 271939, MC-193621), doing business as Knife River, is an active motor carrier based in Tangent, Oregon that FMCSA's census classifies as for-hire and that declares hazardous materials on its MCS-150. Operation: interstate. Operating authority: active for-hire authority (MC). Fleet: 425 power units and 433 drivers (355 with CDLs). Power units count straight trucks as well as tractors, so they can exceed the tractor count. Its MCS-150 of September 19, 2025 reports 9,000,000 miles and gives 2025, the year it was filed, as the mileage year, so the figure is not a full calendar year's total. Cargo classes declared: liquids / gases, garbage / refuse, dry bulk commodities, building materials, construction, machinery, large objects, logs, poles, beams, lumber, drive / tow away, other cargo (other: Redi Mix). It is also classified as a private carrier of its own goods. FMCSA safety rating: satisfactory, from a compliance review on August 18, 2025. In the last 24 months it had 37 roadside inspections, 7 of them (18.9%) with an out-of-service order; 8 reportable crashes (0 deaths, 1 injury); a crash on record does not by itself mean the carrier caused it. Registration (MCS-150) last updated September 19, 2025.

Key facts

Fleet size	100–499 power units Power units, banded. source
FMCSA safety rating	Satisfactory Satisfactory, Conditional or Unsatisfactory after an FMCSA compliance review; most carriers have never had one and are not rated. source
Rating age	Rated within the last 5 years How old the FMCSA safety rating is. A rating reflects one compliance review on that date, not current performance; old ratings say little about the carrier today. source
Registration update overdue	No The MCS-150 was last updated more than two years ago, past FMCSA's two-year update requirement; fleet, driver and cargo figures may be out of date. source
Operation	Interstate Interstate, intrastate hazmat or intrastate non-hazmat, as declared on the MCS-150. source
Cargo classes (MCS-150)	Liquids / gases, Garbage / refuse, Dry bulk commodities, Building materials, Construction, Machinery, large objects, Logs, poles, beams, lumber, Drive / tow away, Other cargo Cargo the carrier declared it hauls on its latest MCS-150 (FMCSA's fixed cargo list). source

USDOT number: The registration number every interstate (and many intrastate) commercial carrier holds.

MCS-150: The registration form carriers file with FMCSA and must update at least every two years; fleet, drivers, cargo and the hazmat flag on this site come from it, as the carrier declared them.

Safety rating: FMCSA's result after an on-site compliance review: Satisfactory, Conditional or Unsatisfactory. A rating is not refreshed unless FMCSA reviews the carrier again, so many are years old; each profile gives the review date. Most carriers have never been reviewed and are not rated; that is not a bad mark.

Power units: Trucks and tractors that pull or carry freight.

Reportable crash: A crash involving the carrier's vehicle with a death, an injury treated away from the scene or a vehicle towed away. FMCSA records it whoever was at fault.

Cargo classes: Self-declared on the MCS-150 from FMCSA's fixed list. Some carriers tick most of the list, so a long list means 'declared', not 'specialises in'; the hazmat flag does not say which hazardous materials.
