Which agency is responsible for the certification of the Intoxilyzer 9000 in Texas?

The Texas Department of Public Safety (DPS) is responsible for the certification of the Intoxilyzer 9000 in Texas. This agency oversees the state's law enforcement and public safety operations, including managing alcohol testing equipment used by law enforcement for breath alcohol testing. The DPS ensures that the Intoxilyzer 9000 operates correctly and meets the standards necessary for evidential use in legal proceedings. Certification includes maintaining the equipment, training officers, and ensuring that testing procedures comply with state laws.

While other agencies have important roles related to public safety and health, their functions do not encompass the certification and maintenance of breath testing devices like the Intoxilyzer 9000. The Texas Department of Transportation focuses primarily on road safety and transportation issues, and the Texas Commission on Environmental Quality deals with environmental protection and regulatory issues. The Texas Alcoholic Beverage Commission, while it oversees alcohol distribution and compliance with alcohol laws, does not handle the technical certification of breath testing devices.
