In Rhode Island, the police have a number of different enforcement techniques when it comes to DUIs. In addition to patrols, they also launch campaigns to encourage driving safely and host a variety of educational classes. A DUI in Rhode Island usually starts as a misdemeanor, although if you have three DUIs within five years, you will face felony charges. Your license may also be suspended, especially if you have prior DUIs on your record. While adults must have the minimum blood alcohol level of .08% to be charged with a DUI, anyone under 21 with any level of alcohol in their system may have their license revoked.
