Securing Infrastructure from Adversaries Act

This bill prohibits U.S. Department of Transportation agencies from procuring or using LiDAR technology produced by companies from China, Iran, North Korea, or Russia in federal contracts or projects. It applies to all Department of Transportation contracts and funded projects starting June 30, 2026, affecting contractors and grantees receiving transportation funding. Contractors must certify they will not use prohibited LiDAR, with limited waivers permitted only for national security needs. The law directly restricts the use of specific foreign technology in U.S. infrastructure development.
