What is an ELD?

What is an ELD?

Authored by Doering Fleet Management

ELD = Electronic Logging Device

An electronic logging device (ELD) is a device that attaches to a commercial motor vehicle (CMV) to synchronize with the engine and record Hours of Service (HOS).1

As defined by the Federal Motor Carrier Safety Administration, a commercial motor vehicle (CMV) is a self- propelled or towed motor vehicle used on a highway for interstate commerce, transporting passengers or property, and meeting certain criteria for weight and design or use.2

The ELD facilitates considerably more accurate recording of all driver activity by providing “snapshots”    of the vehicle’s location throughout the driver’s day.1 ELDs automatically record driving time and monitor information such as location, engine hours, vehicle movement, and miles driven.

Who does the new ELD rule impact?

Essentially all CMV carriers that operate across state lines will be impacted.

Any driver who maintains 8 or more days worth of duty status logs, out of 30 days, will require an ELD.


  1. Driveaway-towaway operations are not required to use an ELD, provided the vehicle driven is part of the shipment; and
  2. ELDs are not required on CMVs older than model year 2000.
  3. Drivers who use paper RODS for not more than 8 days during any 30 day period.

Benefits of ELDs

Paperwork Savings: More Drive Time, Lower Paper Costs

With ELDs, less time is required for processing paperwork and inspections — meaning more time for driving and taking care of business. Automatic logging minimizes the risk of errors. Less paperwork also adds up to cost savings!

Increased Safety, Productivity and Compliance:

ELDs will have a major impact on road safety. The FMCSA estimates that the ELD rule will “save 26 lives and prevent 562 injuries resulting from crashes involving large commercial motor vehicles” each year on average.11 With an ELD solution, fleet managers can see a more complete and accurate picture of their fleet’s activities, making management easier. ELDs increase Hours of Service (HOS) compliance, which prevents driver fatigue. Access to engine fault code information, allows fleets to proactively attend to engine issues early before they turn into costly repairs or vehicle down-time.
