FORM FOR OBTAINING TESTING INFORMATION FROM PREVIOUS EMPLOYERS
49 CFR Part 40.25 requires employers to obtain drug and alcohol testing information from an applicant's previous employers, for the previous two years. Information obtained must include test results, refusals, other violations, and paperwork related to the return-to-duty process (SAP reports). Any information that has been received from other employers may also be sent to the employee's new employer. DOT has provided a form to be used by employers to obtain this information. For a copy of the form, go to http://www.dot.gov/ost/dapc/materials/release_of_information_for1.doc. Save it as a Word document, and customize it as may be appropriate. Note: An applicant's written authorization (signature) is required, and a form, separately signed by the applicant, must be sent to each prospective employer.
