RI DUI BAC Limits

The state does not file a separate "high BAC" charge - it remains DUI under § 31-27-2 - but the penalty tier escalates at 0.10 and again at 0.15.

0.04% - half the standard limit. The threshold applies whenever a CDL holder is operating a commercial vehicle. A CDL holder driving a personal vehicle is held to the standard 0.08% limit.

BAC at or above 0.15 puts the case in the highest sentencing tier under § 31-27-2. License suspension is the longest, fines are the highest, and ignition interlock becomes mandatory rather than discretionary.

0.08% for standard drivers age 21+, 0.04% for commercial drivers, and 0.02% for drivers under 21. A driver may also be convicted of DUI below 0.08 if the state proves actual impairment.

Yes. Rhode Island's DUI statute § 31-27-2 allows conviction under the impairment theory regardless of BAC. The state must prove actual driving impairment by alcohol, drugs, or a combination.
