A “grandfathered” AOBRD is a device that a motor carrier installed and required its drivers to use before the electronic logging device (ELD) rule compliance date of December 18, 2017. The device must meet the requirements of 49 CFR 395.15. A motor carrier may continue to use grandfathered AOBRDs no later than December 16, 2019. After that, the motor carrier and its drivers must use ELDs. See Section 395.15 (a) of the ELD final rule.
