This legislation, titled the Federal Agents Secure Travel Act or FAST Act, aims to enhance security screening efficiency for Federal law enforcement officers. It amends title 49 of the United States Code to specifically make these officers eligible for expedited security screening through the PreCheck Program. Under this bill, Federal law enforcement officers would receive PreCheck access at no cost , a benefit that also extends to their accompanying family members who are younger than 12 years old. The Administrator is authorized to prescribe policies and procedures for the implementation of this new eligibility.
