Frequently Asked Questions
Can a logged-in co-driver make entries over his or her records using the electronic logging device (ELD) when he or she is not driving?
Do the specifications in the ELD rule for electronic logging devices (ELDs) include requirements to automatically control the vehicle, such as other safety systems that may automatically reduce acceleration or apply braking?
No. The specifications for ELDs do not include requirements to control the vehicle. An ELD is a recording device that records vehicle parameters through its synchronization to the vehicle’s engine, and allows for entries related to a driver’s record of duty status (RODS).
Can an electronic logging device (ELD) record be set to record minimum duty status durations, such as 15 minutes?
No. The ELD will capture all entered duty statuses, and there is no minimum amount of time that these statuses must or should be engaged. While longstanding industry and enforcement practices may have relied upon minimum intervals of 15 minutes in handwritten records of duty status (RODS), an ELD provides a more accurate accounting of drivers’ time. This should not be construed to indicate that the activities electronically recorded as less than 15 minutes are suspect, only that the time actually required to complete the task may be less that what had been traditionally noted in the paper RODS.
What is the level of precision for commercial motor vehicle (CMV) location information recorded by an electronic logging device (ELD)?
You should only purchase an ELD that is self-certified by the manufacturer to be compliant and that is registered and listed on the FMCSA website. The list of registered ELDs can be found here. Motor carriers should also familiarize themselves with the ELD checklist and the ELD rule, located here.
What does engine synchronization mean for the purposes of electronic logging device (ELD) compliance?
Will GPS-derived data for mileage be allowed as a substitute for data that cannot be readily obtained from a vehicle electronic control module (ECM)?
Can an electronic logging device (ELD) have a feature to warn drivers about approaching hours of service (HOS) limits?
When will an electronic logging device (ELD) automatically start to record a driving mode or status?
An ELD must automatically switch to driving mode once the commercial motor vehicle (CMV) is moving up to a set speed threshold of five miles per hour. As a result, the in-motion state must not be configured greater than five miles per hour. The vehicle will be considered stopped once its speed falls to zero miles per hour and stays at zero miles per hour for three consecutive seconds.
When will an electronic logging device (ELD) automatically change the duty status from driving to the default duty status of on-duty not driving?
When the duty status is set to driving, and the commercial motor vehicle (CMV) has not been in motion for five consecutive minutes, the ELD must prompt the driver to confirm a continued driving status or enter the proper duty status. If the driver does not respond to the ELD prompt within one minute, the ELD must automatically switch the duty status to on-duty not driving.
How must a driver be able to access records of duty status (RODS) from an electronic logging device (ELD)?
Since all ELD data file output will be a standard comma-delimited file, a driver may import the data output file into Microsoft Excel, Word, notepad, or other common tools. A driver will also be able to access ELD records through a screen display or a printout, depending on the ELD design.
How does the electronic logging device reflect personal conveyance when the personal conveyance status is selected and the commercial motor vehicle (CMV) is driven?
All miles driven are recorded, regardless of the status the driver has selected. However, when the personal conveyance status is selected (as allowed and configured by the motor carrier), the CMV’s location is recorded with a lower level of precision (i.e., an approximate 10-mile radius). Personal conveyance will be reflected on the ELD using a different style line (such as dashed or dotted line).
No. Vehicle location information is not sufficiently precise to identify street addresses. For each change in duty status, the ELD must convert automatically captured vehicle position in latitude/longitude coordinates into geo-location information that indicates the approximate distance and direction to an identifiable location corresponding to the name of a nearby city, town, or village, with a State abbreviation.
