Felonious DWI convictions can lead to steep financial penalties, permanent revocation of a driver's license, and even substantial prison time. When someone is pulled over under the suspicion of driving while impaired, there are a number of tests that a law enforcement officer may use to try and measure someone's blood alcohol concentration, also known as BAC.
In June, Gov. Jay Nixon signed a bill that enhances the penalties for chronic drunk drivers, but also offers alternatives to jail for some offenders. The law, which became effective in August, passed both houses unanimously before being signed by the governor in June.
