Electronic Logging Device (ELD) Rule
An electronic logging device (ELD) is electronic hardware that is attached to a commercial motor vehicle engine to record driving hours. The driving hours of commercial drivers (truck and bus drivers) are regulated by a set of rules known as the hours of service (HOS). The Commercial Vehicle Driver Hours of Service Regulations vary in Canada and the United States.
An ELD monitors a vehicle’s engine to capture data on whether the engine is running, whether the vehicle is moving, miles were driven, and duration of engine operation.
Previously, paper logs or electronic on-board recorders (EOBR) were used for hours-of-service tracking. Even though an electronic on-board recorder (EOBR)-style log improves the accuracy of the data, the lack of a consistent data format meant that the logs needed to be regenerated to an equivalent “paper” format for review and enforcement. The Record of Duty Status (RODS) definition within the ELD legislation defines a consistent format for enforcement personnel to review, so the ELD Mandate was created.
The Federal Motor Carrier Safety Administration (FMCSA) announced the Final Rule of the ELD mandate, and the ELD rule being implemented in several phases with a compliance date of December 18, 2017. Fleets have until December 2017 to implement certified ELDs to record HOS. Fleets already equipped with electronic logging technology will have until December 2019 to ensure compliance with the published specifications.
An ELD is an electronic unit that:
- Records a commercial motor vehicle's driving time
- Records the driver's hours of operation
- Is synchronized with the engine of the vehicle
- Electronically displays and transfers ELD information
- Monitors engine data such as:
- Engine power status
- Vehicle motion status
- Miles driven
- Engine hours
- Records data such as:
- Date & Time
- Geographic (GPS) Information
- Engine hours
- Vehicle miles
- Driver identification
- Vehicle identification
- Records events such as:
- Engine power up and shut down
- Driver login/logout
- Duty status changes
- Personal usage
- Malfunction of diagnostic events
Advantages of ELD:
- Eliminates the need to move and store large amounts of paper.
- Due to automatic recording, ELD can drastically reduce errors plus the additional efforts in resolving these issues with federal authorities.
- ELD simplifies and speeds up the vehicle inspection process with data clearly displayed on the tablet for enforcement officials to view.
- ELD provides the capability to electronically transfer the data to the official’s device.
- ELD reduces paperwork, simplifies communication
- Reduction in violations results in ease-of-mind for drivers, fleet managers, and owners.
