The Employee Polygraph Protection Act (EPPA) establishes specific guidelines regarding the use of lie detector tests in the workplace. Under this legislation, employers are generally prohibited from using polygraph tests for most job applicants and employees. However, there are certain exemptions where the use of lie detectors is permitted, primarily for positions where employees are involved in protecting national security or in certain law enforcement roles.

These exemptions also extend to employers who are in industries that handle certain sensitive situations, such as the manufacture and distribution of controlled substances, allowing them to use polygraph tests to ensure security and compliance. Therefore, the correct answer concerning when lie detector tests can be utilized is based on these specific exemptions for designated job types, highlighting that testing is not broadly applicable but rather limited to certain circumstances outlined by the EPPA.
