Tier 1: Foundational (a gap here is a significant review finding)
- Active operating authority. USDOT active, MC authority in Authorized status.
- Federal-minimum insurance on file. $750K BIPD for general freight, $1M for hazmat, with effective dates that cover the tender.
- No Unsatisfactory safety rating. An Unsatisfactory rating means FMCSA has found the carrier unfit to operate. This requires documented justification for any tender decision.
- No active out-of-service order. An OOS order means FMCSA has ordered the carrier to stop operating.
- Not on your Do-Not-Use list. Tendering to a carrier you previously excluded creates a clear contradiction in your screening documentation.
Tier 2: Standard due diligence
- SMS BASIC alert status. Flag any category in Alert. Multiple alerts is escalation or rejection.
- Crash history (24 months). Any fatal crash requires documented justification for selection.
- OOS rates vs. national average. Driver OOS ~6.5%, Vehicle OOS ~20.7%. 2× or more is a red flag.
- Inspection history. Zero inspections in 24 months is a data gap worth documenting.
- Authority age. New carriers (under 18 months) crash at roughly 2× the rate of established peers.
- MCS-150 currency. Filings over 24 months stale render the rest of the carrier's data unreliable.
- Entity type verification. Broker-only authority means tendering to them is double-brokering.
Tier 3: Gold standard (most thorough documentation)
- Signed carrier safety attestation. Pre-trip inspection, driver fitness, valid CDL, HOS compliance, insurance currency, drug testing program.
- Certificate of insurance on file. Actual ACORD 25, not just the FMCSA filing.
- Broker sign-off. The rep who made the call signs that they personally reviewed the data.
Documenting the screening process
The checklist is the easy part. The hard part is producing a contemporaneous record that shows what was reviewed and when. DOTScreener runs every item above against live FMCSA data, captures a timestamped snapshot, collects the carrier's attestation through a cross-device portal, and produces a tamper-evident, cryptographically linked audit log — all generated automatically at the moment of screening.
