Technically, DUI means driving under the influence of some type drug. Under Maine's Bureau of Motorized Vehicle (BMV), the definition for DUI under code §2401 states "Under the influence of intoxicants" means being under the influence of alcohol, a drug other than alcohol, a combination of drugs or a combination of alcohol and drugs.
The same code defines "OUI" as operating under the influence of intoxicants or with an excessive blood-alcohol level. OUI in Maine is similar to the term DWI used in other states. DWI means simply driving while intoxicated, and in many states, refers to the use of alcohol.
The use of DUI and OUI can be interchangeable, but OUI usually refers more to the severity the drug has metabolized within the offending person's body. Convicted first time offenders can receive jail time, a stiff fine, and driver's license suspension with a conditional reinstatement for one year. The conviction, even a first time conviction, stays on your record permanently.
According to a news article in dui.com and posted July 14, 2009, Effective today, those stopped for suspicion of driving under the influence in Delaware will be facing twice the fines, and repeat offenders could be sentenced to jail for up to 15 years. All across our nation, whatever term you refer to drinking and driving or drunk driving, states are clamping down on these type traffic violations.
When you face these kinds of charges, it is no time to handle your case all by yourself. You may need an attorney who understand the subtle differences in the legal jargon of Maine law, and who specializes in representing YOUR best interests.
