The final rule requires motor carriers, medical review officers, third-party administrators, and substance abuse professionals to report information about drivers who:
- Test positive for drugs or alcohol;
- Refuse drug and alcohol testing; and
- Undergo the return-to-duty drug and alcohol rehabilitation process.
Additionally, motor carriers will be required to annually search the clearinghouse for current employees, and during the pre-employment process for prospective employees, to determine whether a driver violated drug or alcohol testing requirements with a different employer that would prohibit them from operating a CMV.
