Has anyone ever challenged the mandate?

In September of this year (2016) the OOIDA (Owner-Operator Independent Drivers Association) challenged the ELD mandate by presenting their arguments to the SCCA (Seventh Circuit Court of Appeals).

Two of the biggest arguments pointed out by the OOIDA is how the mandate doesn’t meet the standards set by the Congress, and how it violates truckers’ Fourth Amendment rights.

SCCA disagreed with all the points presented by the OOIDA. In other words, the petition to terminate the ELD mandate was dismissed by the court.
