Section 402: State Highway Safety Programs


The State Highway Safety Program, commonly referred to as Section 402, was initially authorized by the Highway Safety Act of 1966 and has been reauthorized and amended a number of times, including most recently on July 6, 2012 under the “Moving Ahead for Progress in the 21st Century Act” (MAP-21).

Section 402 supports State highway safety programs, designed to reduce traffic crashes and resulting deaths, injuries, and property damage. A State may use these grant funds only for highway safety purposes; at least 40 percent1 of these funds are to be used by or for the benefit of political subdivisions of the State to address local traffic safety problems.

The program is administered by the National Highway Traffic Safety Administration (NHTSA) at the Federal level and by the State Highway Safety Offices (SHSO) at the State level.


Those jurisdictions defined as “States” in chapter 4 of Title 23 are eligible to receive Section 402 funds; this includes the 50 States, the District of Columbia, Commonwealth of Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, Commonwealth of the Northern Mariana Islands, and the Secretary of Interior (Bureau of Indian Affairs).

A State is eligible for State Highway Safety Program grants by having and implementing an approved Highway Safety Plan (HSP). The HSP establishes goals, performance measures, targets, strategies and projects to improve highway safety in the State. It also documents the State's efforts to coordinate the HSP, data collection and information systems with the State Strategic Highway Safety Plan (SHSP).

Under MAP- 21, States are required to develop and implement the State highway safety program using performance measures that are data-driven. States must also agree to additional assurances (or certifications) to receive Section 402 funds including State participation in national high-visibility law enforcement mobilizations, establishment of a data-driven enforcement program and coordination of the plan required under Section 402 with the State's Strategic Highway Safety Plan (SHSP), which is a requirement of a State's Highway Safety Improvement Program (HSIP) (23 USC 148). Coordinating these planning processes promotes a unified State approach to highway safety.

Use of Grant Funds

To receive Section 402 grant funds, a State must have an approved HSP and provide assurances that it will implement activities in support of national goals that also reflect the primary data-related factors within the State, as identified by the State highway safety planning process. States can distribute highway safety grant funds to a wide network of sub-grantees, including local law enforcement agencies, municipalities, universities, health care organizations, and other local institutions.

States may spend 402 funds in accordance with an approved Highway Safety Plan that complies with the uniform national guidelines for highway safety programs to:

In addition, States may spend 402 funds on teen driver programs. If they do choose to fund these programs, they must include peer-to-peer education and prevention strategies in schools and communities. Section 402 funds cannot be spent on automated traffic enforcement systems.
