An ELD, or Electronic Logging Device, is a device used in commercial vehicles to automatically record driving time and Hours of Service compliance data. It connects to the vehicle’s engine and tracks information such as engine status, vehicle movement, location, mileage, and driver activity. In trucking and freight logistics, ELDs help replace paper logbooks, reduce manual reporting errors, support safety compliance, and give carriers better visibility into driver availability, route timing, and regulatory limits.
An Electronic Logging Device (ELD) is a hardware device installed in commercial trucks that automatically records hours of service (HOS) data for truck drivers. The ELD mandate from FMCSA requires most commercial carriers to use ELDs to replace paper logbooks.

- Reduces hours of service violations and fatigue-related accidents
- Shippers should be aware that ELD enforcement may reduce driver availability and transit flexibility
