  1. The driver must inform their carrier of the malfunction within 24 hours.
  2. The motor carrier has 8 days to repair, service, or replace the ELD. If the malfunction precludes the device from accurately recording hours of service (HOS) data and presenting that HOS data to a safety official, the driver must user paper logs or another system for recording their HOS during this time.
  3. Under 49 CFR 395.34, a motor carrier seeking to extend the time permitted for repair, replacement, or service of one or more ELDs may request an extension. ELD malfunction extensions can be requested by email to ELD-Extension@dot.gov. You may also contact the field office directly. For more information, see https://eld.fmcsa.dot.gov/support.

If an ELD malfunctions, a motor carrier must:

  1. Correct, repair, replace, or service the malfunctioning ELD within 8 days of discovering the condition or a driver's notification to the motor carrier, whichever occurs first; and
  2. Ensure its driver complies with 49 CFR 34(a)(2) and (3) by requiring its driver to maintain paper record of duty status (RODS), if the malfunction hinders the accurate recording of the driver's hours of service data, until the ELD is back in service.

Note: A motor carrier may file an ELD malfunction extension request via email, by submitting the extension request toELD-Extension@dot.gov or the FMCSA Division Administrator for the State of the motor carrier's principal place of business. The request must include the information required by §  395.34(d)(2).

  • The date and location of each ELD malfunction as reported by the driver to the carrier; and
  • A concise statement describing actions taken by the motor carrier to make a good faith effort to repair, replace, or service the ELD units, including why the carrier needs additional time beyond the 8 days provided by 49 CFR part 34.
