Wyoming DUI Laws
Driving under the influence (DUI) of alcohol or other substances is dangerous and can result in bodily harm or death to yourself, passengers, and other motorists. That is why the DUI laws in Wyoming -- as in other states -- are quite strict and impose stiff penalties for offenders. While it's very rare, a first offense can result in a maximum jail sentence of six months. A fourth or subsequent offense, meanwhile, can result in a maximum two-year jail sentence. In all cases, your license will be suspended for a specified period of time.
