Highway Safety Improvement Program (HSIP)

The new federal surface transportation act, “Moving Ahead for Progress in the 21st Century” (MAP-21), was signed into law on July 6, 2012. Under MAP-21, the Highway Safety Improvement Program (HSIP) remains as one of the core federal-aid programs. The High Risk Rural Roads (HR3) Program is part of the HSIP Program in MAP-21, not a set-aside as in the previous federal surface transportation act.


The specific provisions of the HSIP are defined in Section 1112 of MAP-21 which amended Section 148 of Title 23, United States Code (23 USC 148) to incorporate these provisions. The purpose of this program is to achieve a significant reduction in traffic fatalities and serious injuries on all public roads, including non-State-owned public roads and roads on tribal land.
