An electronic logging device (ELD) is a piece of hardware used to record driving time for commercial motor vehicles. It plugs into a vehicle and captures data on the vehicle’s engine, location, speed, miles driven, and more.


ELDs are mainly used to record Hours of Service (HOS), which includes the number of hours a commercial driver spends driving per day and how many hours they are on- or off-duty per week. ELDs with built-in GPS tracking, gyroscopes, and accelerometers can record additional information, including:

  • – Real-time GPS
  • – Engine speed and load
  •  Fuel efficiency, idling, and mileage.
  •  Diagnostics and safety-related events

We typically ship via FedEx or UPS for domestic shipments, and DHL for international orders.
