Since February 16, 2016, ELD manufacturers have been able to register and self-certify their ELDs with FMCSA, and motor carriers have been able to elect to use ELDs listed on the website. All motor carriers and drivers subject to the requirements in the ELD rule must begin using an ELD or “grandfathered AOBRD” on December 18, 2017, the compliance date of the ELD rule.
