What the federal data says about small carriers

Most writing about trucking describes fleets. Most trucking companies are not fleets. These reports work from FMCSA’s own registration and safety data and are published with the dataset, the date it was pulled and every filter applied, so anyone can reproduce or challenge the numbers.
