About DataQs

Accurate data leads to safer roads.
DataQs is an FMCSA system that allows users to request and track a review of Federal and State data issued by FMCSA believed to be incomplete or incorrect.

It enables all users—motor carriers, drivers and their representatives, as well as FMCSA and its State partners—to improve the accuracy of FMCSA's data-driven safety systems that help prevent crashes, injuries, and fatalities related to commercial motor vehicles.
