Use of Prior Convictions/Prior Misconduct at DUI/DWI Trials

The statutes of almost all states provide for an increased penalty against a person convicted of a second or subsequent charge of drunk driving, with additional penalties ranging from higher fines to mandatory imprisonment and mandatory suspension of a person's driver's license. Since prior convictions are elements of the enhanced offense, they must be charged and proven by the prosecution.

Overview of Open Container Laws

In 1998, as part of the Transportation Equity Act for the 21st Century Restoration Act, a federal program was created to encourage states to enact laws prohibiting the possession of alcohol in the passenger areas of motor vehicles. The federal program essentially provided that if states did not enact the so-called "open-container" laws, the states would be subject to a penalty transfer of federal highway construction funds to the state's safety grant program. Since the passage of the federal act, the vast majority of states have passed "open-container" laws that satisfy the federal requirements.

Elements of Criminal Offense of Driving While Impaired

Drunk driving statutes across the country are not uniform in how they describe the degree of inebriation that is required for conviction for a drunk driving offense. For example, some states have interpreted the terms "intoxicated" and "under the influence" as meaning the same thing, while others have concluded that the two terms represent different levels of impairment. States that view the terms as the same conclude that the degree of inebriation or impairment of the faculties required are the same.

Probable Cause in Drunk Driving Cases

In order to make a lawful arrest for drunk driving, there must be "probable cause" to believe that the driver has violated the drunk driving statute. ''Probable cause'' exists when the facts and circumstances within the officer's knowledge at the time of the arrest are sufficient to warrant the belief by a reasonable and prudent person that an offense has been committed. Probable cause must be based on objective facts and circumstances and not upon the personal opinions or suspicions of the officer. Further, probable cause must exist at the moment of police action and not thereafter.

Elements of Criminal Offense of DUI Manslaughter

If a driver's act of drunk driving results in the death of another person, the driver will be charged with some form of homicide. Some states, however, treat the offense as a form of aggravated drunk driving, variously described as, inter alia, "vehicular manslaughter", "manslaughter with a vehicle," "negligent homicide manslaughter," or "DUI manslaughter."
