Risk factors
Low riskVioCodes scoreA 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.
- Broker authority is inactive, not active.
- 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.

Safety trends & next-run projection
Where each BASIC sits today, how it ranks against peers, and where it’s heading at the next monthly SMS run.
FMCSA keeps the Crash Indicator percentile private, and its measure needs a power-unit history public data doesn’t expose — so it can’t be estimated yet. VioCodes now records power units monthly, so a calibrated Crash estimate should light up over time. These are the public crash facts (all state-reportable crashes count, regardless of fault).
“Projected” estimates the next monthly SMS run from inspections on record now. FMCSA marks the BASIC percentile itself “Not Public,” so the percentile shown is a VioCodes estimate of how the carrier ranks against its peers, presented as a likely range (shaded on the gauge) and calibrated against real carriers. Crash Indicator has no public estimate — FMCSA keeps its measures fully private. Estimates, not official FMCSA figures. Not affiliated with FMCSA.
Recommendations
What’s driving each score, what to do about it, and where it could go.
A high share of violations are occurring in Clay County, MN
Medium impact7 of 35 violations in the last 12 months (20%) came from inspections in Clay County, MN. That can mean tougher enforcement there or simply more of your miles run through it — either way it's worth a look.
- Review the inspections from Clay County, MN to spot recurring issues
- Brief drivers running that lane; consider rerouting around the toughest enforcement corridors where practical

CSA points = violation severity weight × FMCSA time weight (3× in the last 6 months, 2× at 6–12, 1× at 12–24). Points are spread within each state — FMCSA records the inspection state, not an exact location. Source: FMCSA MCMIS.

Connections
carrier graphThis carrier shares VINs or addresses with 24 other carriers — review the connections below as part of your vetting.
Shared VINs come from FMCSA roadside-inspection records — a vehicle inspected under more than one carrier, often a fleet transfer or trailer interchange. Other links come from the FMCSA census. Shared identifiers are common and often legitimate — treat these as leads to investigate, not proof of wrongdoing.
