Building Materials Other: PLUMBING SUPPLIES AND EQUIPMENT Construction

Estimated from the commodity types reported to FMCSA, not from loss history or the true cargo mix.

Not Graded

Not graded: passenger operation. The FRED Score is a model for motor carriers of property; a passenger model is a separate study.

Mileage Unreliable

MCS-150 annual mileage is missing or zero despite observed safety activity. The per-100k-mile rate benchmarks on this page are excluded; the FRED grade does not use mileage (crash exposure is power-unit-years, violation exposure is inspection counts).

Stale MCS-150 Filing

This motor carrier has not updated its MCS-150 in over 3 years. Reported mileage and fleet size may be outdated.

Intrastate operation

Runs within Michigan only. Intrastate fleets in Michigan are inspected about 1 a year for every 16 trucks; interstate fleets, about 1 a year for every 2 trucks. So this record rests mainly on crash reports, which states file for intrastate trucks too, and few inspections are ordinary here.

Worth a closer look

From the FMCSA record.

  • Driver qualification
    2 out-of-service violations against drivers: 1 no valid CDL, 1 medical certificate (Aug 2026).
    Ask: driver qualification files and hiring standards.
Data flags
  • Unreliable reported mileage
    The motor carrier's self-reported annual mileage (MCS-150) looks implausible, so exposure- and mileage-based figures may be distorted.
  • Estimated mileage
    No usable mileage was reported, so exposure was estimated from similar motor carriers. Mileage-based metrics here are approximate.
  • Limited inspection history
    Fewer than 5 roadside inspections on record, so there isn't enough data to score this motor carrier with high confidence — the score leans more on peers.

Insurance filed with FMCSA

Today · live FMCSA check
Checking FMCSA…

No MC, FF or MX docket on FMCSA's registration for this motor carrier, so there are no insurance filings to show. FMCSA collects filings only from registered for-hire authorities; other motor carriers keep proof of insurance (MCS-90) at their place of business.

FMCSA filings only, not a policy audit. Not part of the FRED grade. Wrong or out of date?
