FMCSA Carrier Check API
Carrier and truck verification
Vet a US trucking carrier in one call. Send a USDOT number, MC docket, company name, license plate or VIN and get clean JSON: operating authority, insurance on file vs. required, roadside inspection history and plain-language risk flags. Check whether the truck at your dock really belongs to the carrier you booked, or run 100 carriers in a single request.
