CarrierSafetyData is an independent public-records directory that helps transportation professionals review safety and operating information for more than 336,000 US trucking companies. Using data from official FMCSA SAFER and MCMIS sources, the platform presents complex federal and state records in a more accessible format. Users can look up a carrier by USDOT number or company name and review its operating authority, roadside inspections, out-of-service rates, crash history, insurance filings, fleet size, driver count, and registered contact details.

The directory supports freight brokers, 3PLs, shippers, owner-operators, and commercial drivers seeking to assess carriers before booking freight, monitor compliance, or research potential employers. Its resources explain FMCSA safety scores and inspection records, outline the five roadside inspection levels, and guide users through DataQ violation disputes and double-brokering risks. Additional freight tools include an IFTA fuel tax calculator and a rate-per-mile and cost-per-mile calculator. The site also offers information about state insurance rules and invites users to request profile corrections.
