The Electronic Logging Device mandate went into full effect on December 16, 2019. The rule was originally mandated by Congress as part of MAP-21. MAP-21 was a piece of legislation signed into law in 2012 aimed at updating several aspects of federal highway and vehicle laws and regulations for the 21st century. It took the Federal Motor Carrier Safety Administration (FMCSA) over three and half a years to finalize the electronic logging device rule. The rule then had a delayed phase-in, with larger carriers having to adopt electronic logging devices early and the smallest companies only having to meet the requirement more recently.
While successful court challenges have managed to block a number of high profile regulatory changes in recent months, a Chicago court upheld a major new rule facing the trucking industry at the end of October. The Federal Motor Carrier Safety Administration has issued a rule requiring trucking companies to install electronic logging devices aimed at ensuring compliance with hours of service safety requirements. A legal challenge against this rule brought by the Owner-Operator Independent Drivers Association (OOIDA) failed to succeed.
