What is an ELD?

An ELD is an electronic logging device that is used by drivers of commercial motor vehicles (CMVs) to automatically record driving time and Hours of Service (HOS) records, as well as capture data on the vehicle’s engine, movement and miles driven. The ELD keeps truck drivers and dispatchers informed of driver status in real-time to support fleet compliance, inspections and planning.

ELDs are made up of several parts, including a vehicle tracking device which connects to the truck, fleet management software and a mobile app.
