  2. Carefully review the US DOT PHMSA website for letters of interpretation that may exist. You may find that a DOT special permit is not required because there might have been a previous ruling issued on the subject.
  3. Read the requirements for completing and submitting an application for permit and/or approval very carefully. If any piece of information is missing, chances are you will be denied and have to start the process all over again.
