Gallatin Co. adopted the state's 24/7 DUI program on Monday.
The program allows judges to order twice daily breath tests for repeat offenders. Sheriff Brian Gootkin and representatives from law enforcement agencies were on hand at the jail to discuss the program.
The program is designed to ensure that repeat offenders are staying sober.
Gallatin Co. Commissioner Steve White says he and other county commissioners are on board, "I wasn't really too aware of it and as I heard more about it we became very strong supporters of it. And I think in the next weeks or months it's going to be very interesting to see the changes that can occur."
Tests cost $2 each and are paid for by the offender.
Lewis and Clark Co. tested the program before the state adopted it, and Sheriff Leo Dutton says they've seen over 99 percent compliance.
