(a) Section 10 of EPPA provides that the Act, except for subsections (a), (b), and (c) of section 7, does not preempt any provision of a State or local law, or any provision of a collective bargaining agreement, that prohibits lie detector tests or is more restrictive with respect to the use of lie detector tests.

(b)(1) This provision applies to all aspects of the use of lie detector tests, including procedural safeguards, the use of test results, the rights and remedies provided examinees, and the rights, remedies, and responsibilities of examiners and employers.

(2) For example, if the State prohibits the use of polygraphs in all private employment, polygraph examinations could not be conducted pursuant to the limited exemptions provided in section 7 (d), (e) or (f) of the Act; a collective bargaining agreement that provides greater protection to an examinee would apply in addition to the protection provided in the Act; or more stringent licensing or bonding requirements in a State law would apply in addition to the Federal bonding requirement.

(3) On the other hand, industry exemptions and applicable restrictions thereon, provided in EPPA, would preempt less restrictive exemptions established by State law for the same industry, e.g., random testing of current employees in the drug industry not prohibited by State law but limited by this Act to tests administered in connection with ongoing investigations.

(c) EPPA does not impede the ability of State and local governments to enforce existing statutes or to enact subsequent legislation restricting the use of lie detectors with respect to public employees.

(d) Nothing in section 10 of the Act restricts or prohibits the Federal Government from administering polygraph tests to its own employees or to experts, consultants, or employees of contractors, as provided in subsections 7(b) and 7(c) of the Act, and § 801.11 of this part.
