The "Trucking Security and CCP Disclosure Act of 2026" introduces new requirements to bolster the security of Department of Defense (DoD) freight transportation. It mandates that any motor carrier, including subcontractors and owner-operators, seeking to transport DoD cargo must submit a **certification**. This certification attests that the carrier is not owned or controlled by, nor has significant business relationships with, entities identified on the list of **Chinese military companies**. Additionally, the bill establishes a **Secure Defense Freight Carrier Registry** under the Federal Motor Carrier Safety Administration, in coordination with the Secretary of Defense. To be included, motor carriers must undergo **enhanced national security vetting**, screening for ties to Chinese military companies or other **foreign adversary entities**, and verifying personnel security standards. After one year, only registered carriers may bid on or perform DoD freight contracts, with waivers possible for exigent circumstances. Carriers providing false certifications face penalties, including suspension or debarment from DoD contracting.
