ELD Glossary of Terms

Back to ELD

Bluetooth – a communications pathway used by Pacific Track and 4230 ELD devices that wirelessly transmits data from the ELD to the Driver app. Has range of about 20-30 feet.

Carrier – A motor carrier transports passengers or property for compensation

CMV (Commercial Motor Vehicle) – A vehicle of certain weight and cargo requirements that is used commercially to transport passengers or property.

Cycle – The day and hours that a Driver can work, whether driving or not,

Diagnostics Event – The ELD fails to detect diagnostics from the vehicle ECM as required

Department of Transportation (DOT) – The United States governmental department that regulates transportation (including trucking and commercial passenger transport).

Driving – The driver is actually driving the vehicle.

Driver Exception – Circumstances that the DOT has identified under which the HOS regulations may need to be bent. Please research directly with DOT to determine when and for how long Exceptions may be used.

DVIR (Driver Vehicle Inspection Report) – At the completion of each day’s work, a driver is required to prepare a report listing any maintenance defects found in the vehicle or trailer. Many ELDs include a DVIR form in their daily HOS process for the driver.

ELD Admin Portal – Web-based software from which the HOS records entered by Drivers can be viewed by their supervisors.

ELD Driver App – application installed on a Driver’s phone or tablet, used to input their HOS records

FMCSA  (Federal Motor Carrier Safety Administration) – An agency within the DOT that regulates the commercial transportation industry and tries to improve overall safety.

Hours of Service (Hours oService) – A professional driver’s time, as regulated by the DOT. Hours of Service are tracked using a log of time spent in various statuses: On Duty, Driving, Off Duty, and Sleeper Berth. Limits are placed on how much a driver can work, and how much time he must take time off to rest.

Logbook – the records kept by the Driver of all activity

Malfunction – indicates that the ELD is not functioning properly

Off Duty – The driver is not working. Their time is 100% their own.

On Duty Not Driving – The driver is doing work other than driving, such as fueling, inspection, unloading freight, etc.

Personal Use – When the driver is using the vehicle on his own time for personal transportation. This time does NOT count against a driver’s log time; it is counted as Off Duty time. But as of the mandate, personal driving must be visible on the ELD device for law enforcement.

Roadside Inspection – when a DOT officer reviews the Driver’s logbook for compliance while the Driver is in the field.

Shift – The amount of time the Driver is permitted work per 24 hour period, whether driving or not.

Sleeper – The driver is resting in the truck’s sleeper area.

Terminal – the ‘home base’ for vehicles, drivers and trailers. The air-miles distance from this location determines when the DOT regulations regarding Hours of Service kick in.

Trailer – object being pulled by the the vehicle. Doesn’t require an ELD to be aboard but must be selected within the ELD App to show which trailer is being used at any given time.

Vehicle – the ‘pull unit’ into which the ELD unit is installed

Violation – a recorded infraction of the rules set by the DOT regarding CMV’s, including but not limited to:  exceeding the allowable Hours of Service, not maintaining the vehicle, etc….

Yard Move – The ELD Mandate has introduced a new special status called “Yard Move”. The exact rules for using this status are not yet completely clear, but the idea is that driving done in a limited access lot or yard can be performed in On Duty status (rather than Driving status). The goal here is to allow drivers to move their trucks within a large facility, without counting that as real road-driving time. It may apply to moving within truck stop parking lots as well, but this is not yet clear.
