This summary of the informal rulemaking process was prepared to help the public better understand how the rulemaking process works so that you may more effectively participate in it. We prepared it particularly for individuals, small businesses, and others who do not participate in the process on a regular basis. We want to stress that this web page provides only a brief summary – and one that we attempted to keep simple – of what we believe are the important elements in the process. It should not be relied on as a legal document.
This page includes a separate report for each of 21 possible, different effects for DOT's current rulemakings. The information that appears is the most current information in our database.
