On October 1, 2012, the U.S. Department of Transportation's (DOT) Federal Motor Carrier Safety Administration (FMCSA) published a Federal Register notice [77 FR 59840] informing motor carriers and enforcement officials of two statutory exemptions in MAP-21 that took effect on October 1, 2012,for certain motor carriers transporting agricultural commodities and farm supplies. Since that time, FMCSA has received numerous inquiries from enforcement officials and motor carriers looking for answers to specific questions. Below FMCSA has compiled a list of those questions and answers, and is sharing them to expand knowledge among the enforcement and agriculture communities. Nothing contained below is meant to expand or limit the statutory exemptions. It is provided simply as answers to questions the Agency has received.
