This legislation, known as the Nicholas Douglas Quets Border Travel Safety Act , establishes a program to install and maintain warning signage for travelers near the United States' southern border. The Secretary of Homeland Security, through U.S. Customs and Border Protection and in consultation with the Secretary of State, is tasked with implementing this program. The signage will inform travelers about dangerous areas or routes identified in relevant Department of State Travel Advisories, aiming to improve awareness of safety and security risks. The Department of State will identify these dangerous areas near the U.S.-Mexico border and provide updated advisory information for the signage content. Signage will be placed at land ports of entry, on approaching roadways, and in immediately adjacent areas, ensuring clear visibility for motorists and pedestrians to make informed travel decisions. The content must clearly warn travelers, provide references to additional safety information like the Department of State's travel advisory website or a QR code, and be displayed in English, Spanish, and other appropriate languages. The bill emphasizes that the signage should be in a format that can be swiftly and easily updated to reflect changes in the Department of State's Travel Advisory risk indicators, such as crime, terrorism, or kidnapping. The Secretaries of Homeland Security and State are required to annually review and update the signage to ensure accuracy and visibility. Furthermore, the bill mandates reports to Congress on the program's implementation and efficacy, while explicitly stating it does not authorize the use of force in Mexico.
