The US Federal Motor Carrier Safety Administration (FMCSA) mandated the use of ELD for commercial vehicles from December 18, 2017. A 2-year window, till December 16, 2019, has been provided for vehicles that already have ELDs in place to update these devices as per FMCSA’s ELD technical specifications. Electronic logging device, also known as digital tachograph in Europe, is designed to record data related to the operation of the vehicle and driver activity. The driver information mainly concerns the hours of service (HOS), breaks, and driving behavior. The fleet operators are restricted to a maximum number of hours they can drive between rest periods. According to FMCSA, the ELD mandate will result in a USD 2.44 billion savings, most of which will be attributed to the amount of time drivers will save by not having to complete and submit time logs. In 2006, a similar mandate was implemented in European countries. As per the rule, from May 2006, all new vehicles over 3.5 ton in Europe had to be equipped with a tachograph. Later, in 2016, the European Commission adopted legislation defining new technical specifications for smart tachographs.
