Can a DUI/DWUI be “pleaded down” to a "wet reckless" in Wyoming?

In some states, it’s possible for a driver who’s charged with driving under the influence, to “plea bargain” for a lesser charge. When a DUI is plea bargained down to a reckless driving charge, it’s sometimes called a “wet reckless.”

Wyoming law restricts plea bargaining in DUI cases. So, for someone who’s accused of drunk driving in Wyoming, it typically isn’t possible to plead to reckless driving or any other reduced charge. (Wyo. Stat. Ann. § 31-5-233(j) (2017).)
