"The Federal Highway Safety Act of 1966 directed the U.S. Department of Transportation to administer various highway safety programs. This grant program provides federal funds administered through the Ohio Department of Public Safety, Ohio State Highway Patrol (OSHP) and Ohio Traffic Safety Office (OTSO) to eligible entities to be used for projects such as traffic safety education, enforcement and engineering. Funds are used for highway safety support based on problem identification to reduce overall fatal and injury crashes. This program operates on a reimbursement basis."
