Fact Sheet: Electronic Logging Device (ELD) rule for trucks and buses

What's happening? How are Senators helping?

December 11, 2017

On December 16, 2015, the U.S. Department of Transportation’s (DOT) Federal Motor Carrier Safety Administration (FMCSA) published a final rule requiring the use of an electronic logging device (ELD) for carriers and drivers who are already required to maintain records of duty status (hours operating a commercial truck or bus). Beginning December 18, 2017, a covered driver stopped for roadside inspection without a required ELD will receive a citation, however they will not count against a carrier’s Safety Measurement System (SMS) scores. Beginning April 1, 2018, vehicles stopped for inspection that do not have the required ELD will impact SMS scores and no longer allowed to operate without an ELD.

What is the purpose of the ELD rule?

FMCSA says the new ELD rule “is intended to help create a safer work environment for drivers, and make it easier and faster to accurately track, manage, and share records of duty status (RODS) data.” An ELD automatically records driving time for an easier and more accurate accounting of hours of service. As a result, according to FMCSA’s analysis, the new rule will prevent an estimated 1,844 crashes, 562 injuries, and save 26 lives every year.

How is the new ELD requirement related to existing hours of service (HOS) rules?

From FMCSA:

“The FMCSA hours of service rules are designed to eliminate the type of drowsiness that can lead to crashes. Although many commercial motor vehicle (CMV) drivers feel that they know when they are getting drowsy, various laboratory tests have shown that persons are not good at estimating their own drowsiness.”

ELDs are intended to replace paperwork tracking of HOS rules compliance and modernize enforcement. By automatically monitoring core truck operations and allowing operators to digitally input information on rest breaks and other exemptions, ELDs should not affect operations for drivers who adhere to existing rules. Respecting the privacy rights of drivers, ELDs electronically monitor operation of a vehicle but do not record audio or video.

We’re listening. How could changes to hours of service rules could help you and highway safety?

In an effort to examine possible hours of service rules relief for drivers, while maintaining safety, tell the Commerce Committee about your situation.

By April 1, 2018, please e-mail any suggestions to truckrules[at]commerce.senate.gov. Please include a brief description of your situation or business and your suggestions for improving driver safety and efficiency, specifically as it relates to hours of service.

For example:

My business: hauling cattle
HOS: More flexibility on sleeper berths
Benefits: Allows drivers to breakout sleeper berth time to accommodate for unique conditions of hauling cattle

While the committee will not be able to reply to all messages, we will read all suggestions and use the information to continue the conversation on driver relief. Please note, we may use some information we receive in our public legislative efforts so please note in your submission any request for confidentiality.
