DUI fines in Rhode Island scale by offense level and BAC. First-offense fines are $100 to $300 at a BAC of 0.08 to 0.10, $100 to $400 at 0.10 to 0.15 (or unknown), and $500 at 0.15 or higher. A second offense within 10 years carries a $400 fine, or at least $1,000 at 0.15 or higher. A third offense carries a $400 fine, or $1,000 to $5,000 at 0.15 or higher. Every conviction also adds a $500 highway assessment and an $86 fee. DUI with bodily injury carries fines up to $5,000. DUI manslaughter carries fines from $5,000 to $20,000. Court-imposed fines are only part of the total cost. DMV reinstatement fees, ignition interlock device costs, increased insurance premiums, DUI education program tuition, and lost wages typically push the real cost into the low five figures for a first offense and significantly higher for repeat offenses.
