Department of Homeland Security Vehicular Terrorism Prevention and Mitigation Act of 2025

HR 1608 requires the Department of Homeland Security (DHS) to submit a detailed report to Congress within 180 days of enactment, assessing vehicular terrorism threats and countermeasures. The report must analyze emerging risks - including threats using autonomous vehicles, ride-sharing apps, and connected car technologies - and identify high-risk locations like airports, mass gatherings, and critical infrastructure. It also mandates DHS to detail current prevention efforts, coordination with state/local governments and private companies (e.g., ride-sharing platforms), and recommendations for new technologies like vehicle immobilization systems. An unclassified summary of the report will be published publicly, with annual briefings to Congress on findings.
