Wyoming is one of 12 states without sobriety checkpoints. They include two other states with high DUI rates -- Alaska and Idaho -- and one with among the lowest DUI rates -- Rhode Island, which also has a low incidence of drunken driving deaths.The Wyoming Association of Sheriffs and Chiefs of Police told the Wyoming Tribune Eagle in December that drinking and driving was the most common offense for which people are arrested. Car insurance rates in Wyoming rise by an average of 57 percent a year after a DUI conviction. 2. South Dakota In its 2015 analysis, WalletHub called South Dakota the most lenient state in the nation in combating drunken driving, pointing out that the state has no minimum jail sentence for first or second offenders, no mandatory vehicle impound or license suspensions and no required ignition interlock devices. In 2014, it had the second highest rate of DUI arrests in the country, according to an analysis of FBI data by CarInsurance.com, with 78.6 arrests for every 10,000 residents. It had the seventh highest rate of drunken driving fatalities, at 5.4 for every 100,000 residents, or 46 people killed in 2014. An analysis by CarInsurance.com, found that insurance rates increased by an average of 41 percent in South Dakota following a DUI conviction, less than all but one other state and well below the nationwide average increase of 76 percent. 1. North Dakota As the nation's rate of drunken driving deaths decreased -- by 29 percent from 2004 to 2013 -- North Dakota's increased, by 60 percent. In 2013, the state strengthened its drunken driving laws, increasing fines, doubling jail time for repeat offenders, and mandating minimum prison sentences for DUIs that cause injury to one year, and for those that cause death to three years. "No get out of jail free card anymore," one legislator announced. Those convicted of two DUIs within seven years are now also required to enroll in a sobriety program that includes twice-daily alcohol tests.
