A second-offense Rhode Island DUI within 10 years, with a BAC under 0.15 or unknown, carries 10 days to 1 year in jail (the 10-day minimum cannot be suspended), a $400 fine, a license suspension of 1 to 2 years, an ignition interlock requirement, required alcohol or drug treatment, and a permanent criminal record. At a BAC of 0.15 or higher, the penalties jump to 6 months to 1 year of mandatory jail, a fine of at least $1,000, and a 2-year license suspension. Every conviction also adds a $500 highway assessment. Defense work focuses on reducing the charge (to a first offense, reckless driving, or dismissal) before the mandatory minimum applies.
