Electronic Logging Devices

An ELD is a device that connects to a commercial truck’s engine to automatically record driving hours and other data for Hours-of-Service (HOS) compliance. It replaces paper logbooks and ensures drivers follow federal HOS rules, improving accuracy and safety by electronically tracking when a driver is on-duty or off-duty.

Most commercial truck drivers who must keep hours-of-service records are required to use an FMCSA-compliant ELD. Only a few exemptions exist, such as short-haul drivers or vehicles manufactured before 2000. If you don’t qualify for an exemption, you must have an ELD installed to stay compliant with federal regulations.

ELD devices for trucks are Electronic Logging Devices that automatically record driver Hours of Service in compliance with FMCSA regulations. These ELD trucking devices connect to the vehicle engine to capture drive time, support tamper-proof electronic truck logs, and provide GPS data for compliance and fleet visibility.

The best ELD device is one that is FMCSA-certified, supports all diagnostic ports (J1939, J1708, OBD-II), and combines logging with GPS telematics. Choosing a reliable, all-in-one unit reduces hardware costs and simplifies compliance.

Most ELDs are plug-and-play hardware that connect directly to the diagnostic port. Installation takes minutes and requires no permanent modifications, making it easy for drivers or fleet managers to self-install.

Yes, many ELDs include built-in GPS and LTE telematics, allowing fleets to track vehicles in real time, monitor driver behavior, and generate audit-ready IFTA fuel tax reports — all from a single device, like Dashcam ONE.

Modern ELDs are designed to work with all major vehicle protocols: J1939, J1708, and OBD-II. This allows fleets to use the same device across mixed-duty fleets without compatibility issues.
