The electronic logging device (ELD) rule – congressionally mandated as a part of MAP-21 – is intended to help create a safer work environment for drivers, and make it easier and faster to accurately track, manage, and share records of duty status (RODS) data. An ELD synchronizes with a vehicle engine to automatically record driving time, for easier, more accurate hours of service (HOS) recording.

The ELD Rule:

  • Specifies who is covered by the rule and exceptions to it.
  • Provides for ELDS to be self-certified and registered with FMCSA.
  • Includes technical specifications to ensure ELDs are standardized and compliant.
  • Includes a phased implementation timeline to give drivers and carriers time to comply.
  • Includes provisions to help prevent data tampering and harassment of drivers.
  • Creates standard data displays and data transfer processes, making it easier to demonstrate compliance and faster to share RODS with safety officials.
