Final answer:
The statement that a vendor or C/TPA can provide drug and alcohol testing services is true. C/TPAs manage various aspects of the testing program in compliance with federal regulations and maintain impartiality.
Step-by-step explanation:
The statement is true. Drug and alcohol testing services can indeed be provided by a vendor or a consortium/third-party administrator (C/TPA). A C/TPA manages all, or part, of an employer's DOT drug and alcohol testing program, sometimes handling everything from random drug and alcohol testing to result reporting. Companies often outsource these services to ensure that testing is done in compliance with federal regulations and to maintain a level of impartiality in the testing process. This is especially important in industries that are heavily regulated, such as transportation or safety-sensitive positions where drug and alcohol testing is mandatory under the Department of Transportation (DOT) regulations.
