Rhode Island Ignition Interlock DWI Laws

Information on Rhode Island’s DWI and Ignition Interlock Laws

When you are arrested for a DWI in Rhode Island, your license can be suspended in two different ways.

An Administrative Suspension happens automatically if you fail a breath test, or refuse to take one. The RI DMV imposes penalties in this case, but you can request a hearing to challenge your administrative suspension.

You can also undergo judicial suspension, from the criminal court. This occurs when you are sentenced by a court after a trial or plea agreement.

You must deal with both types of suspensions separately in the state of Rhode Island. For example, an administrative judge can dismiss your DWI, but you will still have to appear in court to face criminal charges.

The severity of the criminal penalty depends on your blood alcohol concentration (BAC). Rhode Island determines DUI penalties using three BAC levels: .08 to .10, .10 to .15, and .15 or higher.

For 3rd DWI an ignition interlock device is mandatory for two years after sentence.

Rhode Island Administrative DWI Penalties include loss of license for 45 days to two years, mandatory substance abuse assessment and treatment, possible ignition interlock installation, and possible vehicle confiscation.

There are additional fines and suspension periods for refusing a BAC test and for underage DWI. You can find that information and more on the RI DMW website.
