The Oklahoma Highway Safety Office (OHSO) was established in 1967 by the Oklahoma Legislature, as a direct result of the National Highway Safety Act of 1966, to combat the alarming increase in the number and severity of traffic crashes and fatalities. The OHSO is under the umbrella of the Department of Public Safety.
The OHSO works closely with local governmental organizations, state agencies, law enforcement agencies, and others to develop the State Highway Safety Plan and programs to address highway safety issues. The programs are federally funded through the National Highway Traffic Safety Administration (NHTSA). Most programs and activities fall into the areas of traffic safety education, training, and enforcement enhancement.
