Instrument and Operator Certifications

Through action by the Indiana General Assembly during the 2017 session, ISDT is no longer required to mail breath test program certifications to the circuit court clerks since the information is published on the department website. Due to this legislation, ISDT no longer mails breath test instrument or breath test operator certifications to circuit court clerks effective July 1, 2017. Certifications issued after July 1, 2017, are available to anyone through an online program at No password is required, nor is there a cost associated with accessing or printing a certified copy of the information. ISDT’s objective is that the online program will increase access to this information and be more efficient for everyone. Certifications issued before July 1, 2017, may not be available online and may have to be obtained from circuit court clerks or from ISDT.
