Tribal Transportation Program Safety Fund (TTPSF)

Transportation fatalities and injuries severely impact the quality of life in Indian country. Each year under the Bipartisan Infrastructure Law (BIL), as enacted by the Infrastructure Investment and Jobs Act (Public Law 117-58), 4% of the available TTP funds are set aside to address transportation safety issues identified by federally recognized Indian tribes through a competitive, discretionary program. Projects are chosen whose outcomes will reduce fatal and serious injuries in transportation related incidents, such as motor vehicle crashes.

FHWA advocates the development of strategic transportation safety plans as a means for tribes to determine how transportation safety needs will be addressed in and around tribal communities. See additional information on developing safety plans.

Eligible projects for the TTP Safety Fund include:

  • develop and update transportation safety plans
  • safety data assessment, improvement, and analysis
  • systemic roadway departure countermeasures
  • infrastructure improvements and other eligible activities as listed in 23 U.S.C. 148(a)(4)
