Any self-propelled or towed motor vehicle used on a highway in interstate commerce to transport passengers or property and meets at least one of the following criteria: weighs more than 10,000 pounds, has a gross vehicle weight rating or gross combination weight rating of more than 10,000 pounds, transports 16 or more passengers not for compensation or nine or more passengers for compensation, or transports hazardous materials in a quantity requiring placards.
Compliance, Safety, Accountability (CSA)
The Compliance, Safety, Accountability (CSA) program is a Department of Transportation initiative that allows the FMCSA to track and evaluate carriers based on compliance and crash history. Carriers that do not score well in the system can be investigated and warned by the FMCSA.
Also called Record of Duty status or driver log, duty status is the document used by a driver to record his/her driving time. There are four different status activities, namely “Off duty” or “OFF”; “Sleeper berth” or “SB”; “Driving” or “D” and “On-duty not driving” or “ON”.
See ‘Duty status’.
Driver Vehicle Inspection Report (DVIR)
Daily report of any maintenance defects in the vehicle. Many ELDs include a DVIR form in their daily HOS process for the driver.
Electronic logbooks (e-Logs)
Short for electronic logbooks, which are records of driving hours that are captured and stored electronically using an on-board recording device.
Electronic Control Module (ECM)
A device that stores engine data, fault codes and hard-braking and stopping information.
Electronic On Board Recorder (EOBR)
An outdated term that replaced AOBRD. This term has been replaced by ELD.
An action by a motor carrier towards one of its drivers that the motor carrier knew, or should have known, would result in the driver violating the HOS rules.
Hours of Service (HOS)
Hours of Service (HOS) regulations are issued by the FMCSA and govern the maximum hours all motor carriers and drivers can operate a commercial motor vehicle (CMV) in interstate commerce in the United States.
Location data, in the context of vehicle tracking, is information provided by an on-board device about its current position in space. For the purposes of an ELD, geo-location must be derived from a database that contains all cities, towns, and villages with a population of 5,000 or greater.
Logging Software Programs
Logging software programs are used by certain drivers to help them prepare RODS, but the computers, tablets, and smartphones with such software do not meet FMCSA’s requirements for automatic on-board recording devices (AOBRDs).
