Inspection challenge

A motor carrier may challenge information contained on an inspection report by submitting a request through the Federal Motor Carrier Safety Administration's DataQ website.

Carriers are encouraged to utilize the DataQ website as needed, but also utilize the toll-free information line at 800-925-6469 to obtain answers to questions on violations and regulatory issues that may need clarification.  In addition, violations involving a citation will not be changed through a DataQ challenge until the courts have issued disposition of the citation or a supervisory review of the citation has been made. A carrier who believes a supervisory review of a citation is necessary should contact the Iowa DOT's Office of Motor Vehicle Enforcement at 800-925-6469 or
