Risk factors

Low riskVioCodes score
5 crashes in the last 24 months

A weighted read of the public FMCSA signals below — authority, insurance, out-of-service, crashes, roadside OOS rates, and carrier connections. A starting point for vetting, not a guarantee.

Broker payment signals

Bond, cancellation & authority risk for this broker — from free FMCSA records.

  • Authority revoked 9 times historically (reinstated) — a pattern worth noting.
  • Bond has changed hands 16 times across 6 sureties — churn can signal payment or coverage trouble.

These are FMCSA bond & authority signals — not a credit report. A filed bond cancellation is the biggest early warning that a broker may stop paying, but days-to-pay and slow-pay history aren’t public FMCSA data — verify those with a broker-credit service or references before extending terms.

Authority & insurance

Source: FMCSA Licensing & Insurance (L&I), public data. This shows the carrier’s federal insurance filings (BMC-91X liability, BMC-34 cargo) — the federally-required minimums on file for operating authority — not the carrier’s full commercial policy (its actual auto combined-single-limit, general liability, cargo, or workers’ comp, which appear on the carrier’s ACORD certificate of insurance). Always confirm current coverage with a COI from the carrier’s agent before making a vetting decision.
