Governor Hearnes created the Missouri Division of Highway Safety by executive order on August 22, 1969. This came out of the Highway Safety Act of 1966. Shortly thereafter, he created the "Police Traffic Services Committee". The first meeting of this committee was held on October 12, 1971.
On March 13, 1974, the committee was replaced with the "Missouri Division of Highway Safety Police Traffic Service Advisory Council". In 1990, the name was changed to "LETSAC" to better include all law enforcement and not just police.
The purpose of the Law Enforcement Traffic Safety Advisory Council (LETSAC) is to provide recommendations, direction, guidance, and information/training to the law enforcement community in the State of Missouri.
This may include implementation of priorities of the Highway Safety Act, as requested by the Assistant to the State Highway Safety and Traffic Engineer of the Missouri Department of Transportation, the Department of Public Safety, and other agencies as requested.
