What are the options for electronic logging devices (ELDs) to electronically transfer data?

According to the ELD rule technical specifications, an ELD must support one of two options for electronic data transfer:

  1. The first option is a “telematics” transfer type ELD. At a minimum, it must electronically transfer data to an authorized safety official on demand via wireless Web services and email.
  2. The second option is a “local” transfer type ELD. At a minimum, it must electronically transfer data to an authorized safety official on demand via USB2.0 and Bluetooth®.

To ensure that law enforcement is always able to receive the hours of service (HOS) data during a roadside inspection, a driver must be able to provide either the display or a printout when an authorized safety official requests a physical display of the information.
