Regulations for the transportation industry require alcohol and drug testing. In accordance with appropriate guidelines, an employer required to conduct alcohol and drug testing of an employee who holds a commercial driver’s license must report the following to the state Department of Public Safety:
• A valid positive result on an alcohol or drug test and whether the positive result was a dilute specimen;
• A refusal by an employee to provide a specimen for an alcohol or drug test; and
• An adulterated or substituted specimen was provided for an alcohol or drug test.
The confidentiality of the records must be maintained by the department for those employees holding a commercial driver’s license and may be released only to the holder of the license, the holder’s current employer, or a person acting on behalf of the employer if the department receives the holder’s specific written consent to the release of information.
