You need to register to use the DataQs system at http://dataqs.fmcsa.dot.gov to file your challenge.
Make the request as timely as possible. While there is no time limit on challenging wrong data, getting the challenge in before two years is up is a no-brainer.
Provide relevant and accurate information information, such as report number, date and time and state.
Provide a clear and detailed explanation of what you want reviewed and corrected
Provide as much possible supporting documentation that is valid and relevant. Pictures documenting a supposed maintenance violation, for instance, time-stamped if possible. In events where a violation or inspection is wrongly assigned to your own DOT number or the wrong driver, providing bills of lading, truck registration documents and/or driver’s license, rental or lease agreement copies may be appropriate. This is one of the most important things that you can do.
Keep your request professional, detailed and stick to facts without inserting opinions and emotions into the request.
Follow up as appropriate. It is your right to appeal any final decision made by a state’s DataQs handler.
Once your appeal is completed there is no guaranteed date by which it will be reviewed and approved. It will depend greatly upon how the data flow for your particular appeal falls.
