ELDs are GO for Data Transfer

Starting today, carriers across the country will be using your ELDs to transfer data to FMCSA safety officials.

The ELD compliance date is here!

In the past few months, we have received thousands of test files, registered more than 100 ELDs, and responded to your questions, all in preparation for today. As of December 18, 2017, FMCSA will be accepting transfers from ELD output files from carriers in the field.

Our servers are up and running and ready to receive your devices’ files. We appreciate all the efforts made on your end to ensure that motor carriers are operating with compliant ELDs, and look forward to continuing to work with you as ELDs become more and more widely used.

Is your ELD listing up-to-date?

FMCSA and motor carriers will continue to rely on the information you provided during your ELD registration to learn more about your devices. Be sure to keep your ELD listing current as you make software upgrades and other changes to your devices.

Q&A: Responding to carrier questions

We appreciate your commitment to customer service as carriers become familiar with these new technical tools. As carriers begin using ELDs in the field, they will likely have questions on how to properly use their devices to record and transfer data. Below are a few tips that may help you address some customer questions.

  • For telematics and Bluetooth transfer, safety officials have been trained in how to supply the output file comment to the carrier. Safety officials will likely refer to this information as either the “safety official code” or “investigation code.”
  • Be sure you have pushed out your most up-to-date software package to all your devices.
  • For USB transfer, you can inform your customers which file system format the device can accept. Sharing that information with the safety official will help them ensure their USB drives are property formatted.

More questions are answered in the updated ELD Technical Specification Frequently Asked Questions. These questions and answers are intended to assist ELD providers in creating ELDs that comply with the ELD rule.
