Can a motor carrier purchase devices in bulk prior to 12/18/17, and install them after 12/18/17 as AOBRDs?
No. Any e-logging devices installed and used for the first time after 12/17/2017 must be a mandate-compliant ELD. To be grandfathered as an AOBRD, the ELog device must be installed and used in a CMV prior to December 18, 2017. If a grandfathered AOBRD breaks and becomes inoperable, that AOBRD must be replaced by a mandate compliant ELD.
