Elements of Driving Under the Influence

The elements of a DUI offense in most states include: (1) driving a motor vehicle; (2) on road or highway; (3) while under the influence of alcohol.[4] However recent state statutes also criminalize DUI's on a [Per Se|per se] basis--i.e. DUI for any individual driving with a Blood Alcohol level of over .08.

Each element has to be proven by prosecution to bring forth a DUI charge. Common issues with proving elements include distinguishing "driving" a vehicle from sitting or waiting in it. The element of proving that defendant is intoxicated is addressed through sobriety tests and symptoms of drunk driving. The driver's Blood Alcohol level is determined through a variety of methods including breathalyzer test, or blood or urine sample.

Sobriety Tests and Checkpoints

Law enforcement officers may ask a driver suspected of driving under the influence to complete field sobriety tests. These may include testing the driver's balance while walking, assessing the driver's ability to pay attention, and the driver's physical ability. The results of field sobriety tests have generally been upheld in court.[5]

State law often allows law enforcement authorities to establish checkpoints to detain drunk drivers. These checkpoints are often synched with holidays associated with alcohol consumption such as New Year's Eve and Fourth of July. The constitutionality of checkpoints has generally been upheld by courts. [6]
