Safety Funding Parity Adjustment Act of 2025

The Safety Funding Parity Adjustment Act of 2025 requires the Transportation Secretary to adjust federal highway safety funding between two specific programs before distributing funds each fiscal year. If the increase in funding for Program A (section 402) is not at least four times the increase for Program B (section 405), funds must be transferred from Program B to Program A to achieve that 4:1 ratio. This mechanism ensures Program A receives a disproportionately larger funding boost relative to Program B when their increases don't meet the 4:1 threshold. The bill directly affects how federal highway safety funds are allocated to states and local governments through these two programs. It takes effect October 1, 2026.
