Driving Under the Influence
In every state, it is a crime for a driver to operate a vehicle while impaired by the effects of alcohol or drugs. The specific offense may be called driving under the influence (DUI), driving while intoxicated (DWI), operating under the influence (OUI), and even operating a motor vehicle intoxicated (OMVI).

Where this punishment is utilized, most states require the DUI offender to pay costs of installation, rental, and maintenance of the ignition interlock device. Rental fees alone can amount to as much as three dollars per day, so a DUI offender's expenses can add up quickly when an ignition interlock device is required.
