(b) Study Factors.—In carrying out the study under this section, the Secretary shall assess— (1) methods for safeguarding the confidentiality of verified positive controlled substances test results; (2) the costs, benefits, and safety impacts of requiring States to maintain records of verified positive controlled substances test results; and (3) whether a process should be established to allow drivers— (A) to correct errors in their records; and (B) to expunge information from their records after a reasonable period of time. (c) Report.—Not later than 2 years after the date of the enactment of this Act, the Secretary shall submit to Congress a report on the study carried out under this section, together with such recommendations as the Secretary determines appropriate. * * * * * * *
