This list is not exhaustive, but includes industries that can be directly impacted by changes in U.S. production and sales of motor vehicles. Below are definitions of these industries.
Some federal clearances for Sensitive Compartment Information (SCI) and other Special Access Programs (SAP) require a polygraph screening examination in addition to a Single Scope Background Investigation.
However, access does not extend to any other compartment; i.e., there is no single SCI clearance analogous to DoD collateral Top Secret. The requirements for DCID 6/4 eligibility (a determination that an individual is eligible for access to SCI), subsumes the requirements for a TS collateral clearance. Being granted DCID 6/4 eligibility includes the simultaneous granting of a TS collateral clearance, as adjudicators are required to adjudicate to the highest level that the investigation (SSBI) supports.
