Code of Federal Regulations Title 23. Highways § 23.924.5 Policy

(a) Each State shall develop, implement, and evaluate on an annual basis a HSIP that has the objective to significantly reduce fatalities and serious injuries resulting from crashes on all public roads.

(b) HSIP funds shall be used for highway safety improvement projects that are consistent with the State's SHSP. HSIP funds should be used to maximize opportunities to advance highway safety improvement projects that have the greatest potential to reduce the State's roadway fatalities and serious injuries.

(c) Safety improvements should also be incorporated into projects funded by other Federal-aid programs, such as the National Highway Performance Program (NHPP) and the Surface Transportation Program (STP). Safety improvements that are provided as part of a broader Federal-aid project should be funded from the same source as the broader project.

(d) Eligibility for Federal funding of projects for traffic control devices under this part is subject to a State or local/tribal jurisdiction's substantial conformance with the National MUTCD or FHWA–approved State MUTCDs and supplements in accordance with part 655, subpart F, of this chapter.
