Chapter 4: DUI / DWI Laws

Driving under the influence of alcohol or drugs is one of the most dangerous choices a driver can make, leading to thousands of preventable deaths and injuries each year. Rhode Island enforces strict laws to combat impaired driving, and understanding these regulations is crucial for all drivers. Knowing the legal limits, the consequences of a violation, and the principle of implied consent is essential for passing the driver’s test and for ensuring you never get behind the wheel while impaired.

This section details Rhode Island’s laws against operating a vehicle while impaired by alcohol or other substances. It defines the legal limits, explains the state’s “Implied Consent” law, and outlines the severe criminal and administrative penalties that result from a DUI or DWI conviction.

DUI & Implied Consent

Driving Under the Influence (DUI) and Driving While Impaired (DWI) are serious offenses in Rhode Island. The charge depends on the driver’s age and their measured Blood Alcohol Concentration (BAC), or if they are impaired by any other drug.

Defining DUI/DWI

A driver can be charged with DUI if they operate a vehicle with a BAC at or above the legal limit, or while under the influence of any drug, alcohol, or controlled substance to a degree that makes them incapable of safe operation. Even if a driver’s BAC is below the legal limit, they can still be convicted if their driving ability is proven to be impaired.
