In 2012, Congress mandated the establishment of national training standard changes for the operators of commercial motor vehicles as part of a highway bill. The Federal Motor Carrier Safety Administration (FMCSA) published a new rule on December 8, 2016. After a 5-month delay for regulatory reviews, the rule setting new national training standards has become law as of June 5, 2017. There is a 3-year compliance window. Carriers, trainers, and others will have until February, 2020 to comply with the new law. The rule applies only to Commercial Drivers' License (CDL) applicants who receive CDLs on or after February 7, 2020.
