How to vet a South Dakota carrier before you book

  1. Confirm active operating authority

    A South Dakota carrier must hold active FMCSA authority for the freight it hauls. Watch for broker-only authority posing as a carrier — the classic double-brokering setup.

  2. Verify insurance on file

    Check that liability and (where relevant) cargo coverage are on file and meet the required minimums — not lapsed or below the requirement.

  3. Read the safety record

    Out-of-service rates versus the national average, crash history, and inspections tell you how the carrier actually operates — not just that it's registered.

  4. Screen for fraud signals

    A VoIP/burner phone, a mail-drop or residential address, or an identity reused across multiple carriers are classic ghost- and chameleon-carrier tells a single lookup misses.

Just the number works — with or without the MC/DOT prefix, and spaces are fine. Tip: prefix an MC number with “MC” (e.g. MC123456) so it isn't read as a DOT number.

Why vetting is a legal issue now

In Montgomery v. Caribe (U.S. Supreme Court, 2026), the Court held that freight brokers can be sued for negligently selecting a carrier — in South Dakota and nationwide. Documenting that you checked a carrier, and when, builds your defensible vetting record.
