ELD (Electronic Logging Device)
An Electronic Logging Device (ELD) is a hardware device installed in commercial motor vehicles that automatically records driving time, engine hours, vehicle movement, and location data, mandated by the FMCSA for Hours of Service (HOS) compliance.
Why It Matters
ELD data is the foundation of GPS-based shipment tracking for truckload freight. The ELD mandate (effective December 2017) created a universal source of vehicle location data across the US trucking fleet. For visibility platforms, ELD integrations are the primary mechanism for real-time FTL tracking.
The FourKites Perspective
FourKites integrates with ELD platforms across 500K+ carriers, polling GPS location data every 15 minutes. The Shipment Twin consumes ELD location pings alongside carrier APIs, mobile tracking, and EDI to produce the most complete tracking signal possible. The Graph uses ELD data quality as a tracking compliance metric in carrier scorecards: carriers with consistent, high-frequency ELD data receive higher tracking quality scores.
