Electronic Logging Device (ELD) System

The Federal Motor Carrier Safety Administration (FMCSA) under authority of the Motor Carrier Act of 1935, the Motor Carrier Safety Act of 1984, the Truck and Bus Safety and Regulatory Reform Act of 1988, the Hazardous Materials Transportation Authorization Act of 1994, and the Commercial Motor Vehicle Safety Enhancement Act of 2012 (part of Moving Ahead for Progress in the 21st Century Act (MAP-21)) published a rule that requires use of electronic logging devices (ELDs) for recording hours-of-service (HOS) information. Under this rule, commercial motor vehicles (CMVs) operated in interstate commerce, by drivers required to maintain records of duty status (RODS), must be equipped with ELDs.  

The agency developed the ELD system to facilitate the transfer of HOS data to authorized safety officials for their review during roadside inspections, investigations, and safety audits. The ELD system facilitates retrieval of data recorded by ELDs and provided in the ELD output file, analysis of the ELD data, and identification of instances of potential non-compliance. The safety official uses the results of this initial assessment to determine if citable HOS violations exist, and to take appropriate action. Examples of these actions include providing a warning of a minor violation, issuing a citation for a more significant violation, or placing a driver out-of-service for a serious violation.
