  • Note the malfunction of the ELD and provide written or electronic notification of the malfunction to the motor carrier within 24 hours;
  • Reconstruct the record of duty status (RODS) for the current 24-hour period and the previous 7 consecutive days, and record the RODS on graph-grid paper logs that comply with 49 CFR 8, unless the driver already has the records or the records are retrievable from the ELD; and
  • Continue to prepare RODS on paper a paper log in accordance with §  8, if the malfunction hinders the accurate recording of the driver's hours of service data, until the ELD is back in compliance.
    • Recording RODS on a paper log cannot continue for more than 8 days after the malfunction unless an extension is given in accordance with §  34 – ELD Malfunctions and Data Diagnostic Events.
    • A driver who records hours of service on a paper log for more than 8 days without proof of an extension from the Federal Motor Carrier Safety Administration may be placed out of service.

A motor carrier domiciled in Canada or Mexico that is subject to the ELD rule must use an ELD when operating in the U.S.

  • If a property-carrying truck is rented for 8 days or less, as indicated in the rental agreement, drivers are not required to use an ELD. To meet this exemption, the driver and motor carrier must maintain the following:
    • A copy of Federal Register Notice (FRN) 82 FR 47306, "Hours of Service of Drivers: Application for Exemptions; Truck Renting and Leasing Association (TRALA)" dated Oct. 11, 2017 or an equivalent signed Federal Motor Carrier Safety Administration (FMCSA) exemption document. This document must be provided to safety officials on request.
    • A copy of the rental agreement. The rental agreement must clearly identify the parties to the agreement, the vehicle, and the dates of the rental period.
    • Copies of the driver's record of duty status (RODS) for the current 24-hour period and the prior 7 days, if RODS are required on those days.

Yes. In this case, the 150 air-mile radius from the source of the agricultural commodity in Canada/Mexico would extend up to 100 air-miles within the U.S. The driver would therefore qualify for the hours of service exemption for agricultural operations while remaining within the U.S. portion of that 150 air-mile radius, provided the trip occurs during the planting and harvesting periods, as determined by the U.S. State or States.

No. The definition of "covered farm vehicle" in § 390.5 includes, among other things, the requirement that the vehicle be "Registered in a State with a license plate or other designation issued by the State of registration that allows law enforcement officials to identify it as a farm vehicle." Because the term "State" means one of the 50 U.S. States and the District of Columbia, motor carriers domiciled in Canada/Mexico are not eligible for the covered farm vehicle exemption, including the hours of service and ELD elements of that exemption.
