What are the enforcement procedures for registered electronic logging devices (ELDs) installed and used in commercial motor vehicles (CMVs) prior to the compliance date of the ELD rule?

Prior to the compliance date of December 18, 2017, ELD use is voluntary. Safety officials will review ELD information to determine compliance with the hours of service regulations and to detect falsifications.
