Data Quality

On October 1, 2002, the Department of Transportation (DOT) issued agency guidelines to ensure the quality of disseminated information. If you are affected by information that the Department has disseminated on or after October 1, 2002 (i.e., if you are harmed because the information does not meet the standards of the guidelines or a correction of the information would benefit you), you may request that the Department correct that information. We regard information originally disseminated before October 1, 2002, as being subject to this correction process only if it remains readily available to the public (e.g., it is posted on a DOT website) and it continues to play a significant, active role in Department programs or in private sector decisions.
