This after a Kentucky man, charged with drunk driving, questions the accuracy of one of their products, a breathalyzer test.

Owensboro police officer Brad Martin has made his share of DUI arrests in his career. Martin says the intoxilyzer 5000 is an important tool to put drunk drivers in jail. That tool is being questioned and the company, CMI Inc. of Owensboro, could be forced to turn over trade secrets to the courts.

The Kentucky Court of Appeals has overturned two lower court rulings in a case between CMI and a defendant who wants proof of the machine's accuracy. 14 News talked to both the Daviess County Sheriff's Department and the Owensboro Police Department. Neither agency questions the accuracy of the machine.
