There are literally hundreds of regulations that apply to carriers. The federal body that oversees regulations is the Federal Motor Carrier Safety Administration (FMCSA), which is part of the U.S. Department of Transportation. The Government Publishing Office maintains a listing of trucking regulations and the FMCSA website provides answers to frequently asked questions.
DAT commonly covers trucking regulations in our blog—especially regulations that are being added, removed, or updated. To get the latest information on trucking regulations, visit the DAT Freight Talk Blog.
