Automatic On-Board Recording Device (AOBRD) and Electronic Logging Device (ELD)

Electronic Logging Devices (ELDs) and Automatic On-Board Recording Devices (AOBRDs) are distinct devices. Starting from December 16, 2019, AOBRDs are no longer deemed compliant with recording of duty status (RODS). The ELD mandate mandates all non-exempt drivers to deploy ELDs that adhere to FMCSA standards.
What is an AOBRD
An Automatic On-Board Recording Device (AOBRD) is a predecessor to the Electronic Logging Device (ELD) and was in compliance with 49 CFR 395.15. This device is connected to a vehicle's engine, recording a driver's Hours of Service (HOS). While it shares some functions with an ELD, it does not meet the specific requirements outlined in the ELD mandate.
How does ELD differ from AOBRD?
In general, Electronic Logging Devices (ELDs) are more restrictive yet significantly more robust compared to Automatic On-Board Recording Devices (AOBRDs). For instance, with ELDs, the driver or fleet manager typically cannot alter driving time, except in certain unique circumstances.
ELDs have the capability to alert drivers about various issues, such as unassigned drive time and recorded miles, during log-ins. This is crucial as all vehicle miles must be accurately accounted for, and ELDs play a role in ensuring the precision of driver logs.
In terms of compliance with various driving events and situations, the regulations governing ELDs are more detailed than those for AOBRDs. A notable distinction is that ELDs automatically shift a driver's duty status to "On-Duty, Not Driving" when the vehicle remains stationary for more than six consecutive minutes. AOBRDs, in contrast, lack this automatic switch requirement and are not obligated to change a driver's duty status when the vehicle is not in motion.
