An electronic logging device (ELD) is a piece of hardware used to record driving time for commercial motor vehicles. It plugs into a vehicle’s onboard diagnostics (OBD) port and captures data on the vehicle’s engine, location, speed, miles driven, and more. This is why ELD devices are sometimes referred to as “telematics” devices; “telematics” is a term used to describe the long-distance transmission of any computerized information.
Equipped with built-in GPS tracking, gyroscopes, and accelerometers, the best ELDs can record:
• Drive time, HOS, and record of duty status for ELD compliance
• Real-time GPS location
• Engine speed and load
• Fuel efficiency, idling, and mileage for
• Diagnostics and fault codes
• Safety-related events, like harsh braking or collisions
