Governor Rick Snyder has signed into law bills that increase penalties for so-called "super drunk" drivers.

The legislation, signed Thursday, doubles the maximum prison term for operating a motor vehicle while intoxicated in cases that result in death or serious bodily injury to another person if the impaired driver has a blood alcohol content of .17 or higher and the accident occurred within seven years of a prior drunken driving conviction.

The state's legal BAC limit is .08.

House Republican Eileen Kowall of White Lake, sponsor of the bills, says "Repeat drunk driving offenders are four times as likely to get into a fatal crash than unimpaired drivers, so we must do all we can to keep these dangerous drivers off the road."

She says increasing the penalties for such offenses sends a clear message that repeat drunk driving will not be tolerated in Michigan.
