Jail time for a Rhode Island DUI varies by offense level and BAC. A first-offense DUI carries up to 1 year jail but most first offenders avoid jail with probation and fines. A second offense within 5 years carries a 10-day mandatory minimum sentence that cannot be suspended. A third or subsequent offense within 5 years is a felony with multi-year prison terms. DUI with serious bodily injury carries up to 10 years prison. DUI manslaughter carries up to 15 years with a 5-year mandatory minimum. Aggravating factors (minor in vehicle, accident, BAC over 0.20) increase jail exposure across all offense levels.
