Penalties for OUI/OWI (Operating Under the Influence or While Intoxicated)

The penalties imposed by states for operating while intoxicated (OWI) and operating under the influence (OUI) follow the same pattern of penalties imposed by states enforcing laws for driving under the influence (DUI) and/or driving while intoxicated (DWI). In general, all states and the District of Columbia have "per se" laws defining it as a crime to drive with a blood alcohol concentration (BAC) at or above a proscribed level of 0.08. percent and above.

Criminal Offense of Improper Lane Usage

A motorist is under a duty to have all of his vehicle on the right side of the road, and while the driver of an approaching car is charged with the duty of exercising proper care to avoid a collision, he has the right to presume that the motorist of the vehicle on the wrong side of the road will move over entirely to his own side. This idea is incorporated into statutes governing improper lane usage. By its terms, if a roadway is divided into two or more marked lanes of traffic, a motorist must stay in his lane of traffic so far as possible or practical and may not move from his lane without first ascertaining that such a movement could be safely done.

Penalties for Drunk Driving

State legislatures have enacted drunk driving laws that impose strict penalties on offenders. One of the mechanisms most widely used to combat drunk driving and increase highway safety is administrative license suspension (ALS).

Warrantless Searches of Automobile Compartments

The law of search and seizure is guided by the Fourth Amendment to the United States Constitution. This amendment, which protects individuals from unwarranted invasions of their privacy interests, requires that searches of private property be performed pursuant to a search warrant. Over time, however, the United States Supreme Court has allowed an exception for warrantless searches of automobiles. The justification for the exception is based upon the mobility of automobiles and the diminished expectation of privacy in automobiles.

Elements of Drunk Driving Offense

Drunk driving laws were enacted almost at the same time as the motor vehicle was invented. Over the years the statutes have been changed and strengthened. In 1982, legislation was passed requiring state drunk driving laws to include provisions for a blood-alcohol level of 0.10 as a per se offense and for license suspensions and minimal sentencing restrictions in order for states to continue to qualify for certain federal funding. Legislation passed in 2000 conditioned the availability of federal highway funds upon the states' adoption of a limit of 0.08.
