Question: Can an electronic logging device (ELD) connect to the electronic control module (ECM) in a manner that relies on internet, Bluetooth® or another method of connectivity?

Guidance: Yes, however, the driver’s record of duty status (RODS) must always be available and current to the last duty status change. Therefore, if the driver is unable to access their RODS for a time period due to operating in an area that has limited coverage, the driver may be cited for violating the hours of service rules or operating without an ELD during that time.

Contact Info: FMCSA ELD Information, 1-800-832-5660 or ELD@dot.gov.
