Visit the new ELD home page

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.
