What is an ELD? ELD stands for Electronic Logging Device. It is DOT-certified electronic hardware that connects to the vehicle's engine to record driving hours. It includes a screen for the driver so they can monitor their current status as well as the ability to print hour logs when required by DOT inspectors.
Any AOBRD installed before December 18, 2017, can be used until December 16, 2019. At that time, any remaining AOBRDs will need to be updated to meet the ELD technical specifications. Electronic on-board recorder (EOBR) was to be the term to replace AOBRDs, but the rulemaking to do so was never finalized. An electronic logging device (ELD) is the most recent term to define an electronic device that is capable of recording a driver's driving hours and duty status automatically.
