Why do I need to complete a Substance Abuse Traffic Offenders Program (SATOP)?

Missouri law requires that every person must file with the Driver License Bureau a SATOP completion form before their driver license may be reinstated if their driver license was suspended or revoked due to the violation of any state, county, or municipal law or ordinance involving the possession or use of a controlled substance, the possession or use of alcohol, the commission of an alcohol related traffic offense, or the alteration, modification, or misrepresentation of a driver license to operate a motor vehicle.
