The Federal Motor Carrier Safety Administration (FMCSA) has
developed a specific mechanism to facilitate data reviews. Requests for data reviews
(RDRs) can be made through the DataQs system, an electronic filing system that
motor carriers, drivers, and the public use. The first step is to register
either at the DataQs website (https://dataqs.fmcsa.dot.gov/), or via the FMCSA Portal.
Instructions for filing an RDR are provided, and include simple forms and the
submission of information such as the report number, date, and time of the
event, State, explanation, and supporting documentation, if needed. Once filed,
the RDR and all relevant documentation are routed to the organization
responsible for the data, and electronic correspondence is used to communicate
with the requestor. The DataQs website is open to the public and offers an
online help function to walk users through the process.
Please Note: A carrier can modify registration information (e.g., name, address, or Power Unit data) by updating the MCS-150 form.
