What will happen if you’re pulled over for drunk driving? All 50 states and the District of Columbia have laws that define a driver with a blood alcohol concentration (BAC) at or above 0.08 as legally drunk. Effective Dec. 30, 2018, Utah’s BAC will be set at 0.05 percent. Forty-eight states and D.C. have increased penalties for convictions for BAC levels higher than .08 Typically, license suspension or revocation follows a conviction for drunk driving. In addition, 44 impose an administrative license suspension, where licenses are taken before conviction when a driver fails or refuses to take a chemical test. All states have some form of ignition interlock program. Twenty-seven states (and four California counties) have made ignition interlocks mandatory or highly incentivized for all convicted drunk drivers, even first-time offenders. An additional three states mandate interlocks for high BACs, eight states require them for repeat offenders; and 8 states for both high BAC and repeat offenders. The remaining four states and D.C. make interlocks discretionary. Another consequence of a drunk-driving violation is that car insurance after DUI is more expensive. The average percentage hike is 80 percent ($1,163 more a year), according to Insure.com’s rate analysis. Review the chart below for more information.
