Safety & compliance
Most carriers are unrated. FMCSA only issues a safety rating after it conducts a compliance review, and it has not reviewed the majority of registered carriers. Unrated does not mean the carrier failed a review — it means no review has produced a rating.
Authority and insurance come from FMCSA's Licensing & Insurance file, last refreshed 14 May 2026; out-of-service status is from the live check above.
Insurance filings on record
A filing on record is not proof of current coverage — ask the carrier for a certificate of insurance before tendering.
Roadside inspection & crash record
Counts published by FMCSA over its rolling 24-month measurement period. QuoteFleet reports these figures as published and does not rate, certify or endorse any carrier.
FMCSA safety data as of Aug 31, 2026. Crash counts are state-reported and are not adjusted for fault or for how many miles the carrier runs.
