Chemical Test Presumptions in Drunk Driving Cases

If you have ever been arrested for drunk driving you were probably given some sort of chemical test to determine your blood alcohol content. The most common chemical tests include a breath test or blood test. Many jurisdictions have statutes that allow prosecutors to give presumptive effect to chemical test readings of blood-alcohol content. In other words, if a person's blood alcohol content is at a certain level, the court will presume automatically that the person was driving under the influence of alcohol. Depending on the jurisdiction, some statutes will use the word "presumption," while others use the term "prima facie evidence."

Overview of Implied Consent in Drunk Driving Cases

Understandably, when a motorist is pulled over for drunk driving, the motorist is generally reluctant to agree to a chemical test because the test results could be used as evidence to convict the motorist of a drunk driving offense. Many states have implied consent laws that essentially provide that a person that drives a motor vehicle is deemed to have given consent to chemical testing of his or her blood or urine for the purpose of determining the alcohol content of the motorist's blood if the motorist is lawfully arrested.

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).

Penalties for Traffic Device Control Violations

Most states maintain statutes directing motorists to obey traffic control devices, including green, yellow, and red signals or arrows, lane direction control signals, stop signs, and yield signs. In addition to directing drivers to obey the directions of traffic control devices, the governing statute will explain the appropriate driver responses to traffic control devices. For example, a statute may direct that a driver stop at a clearly marked stop line as the driver approaches a flashing red light used in a traffic control device or with a traffic sign. These statutes also direct driver responses in the event the traffic control signal is out of operation or functioning improperly.

Sober Living as Alternative Sentencing for DUI/DWI

A court may consider imposing alternative sentencing in lieu of the statutorily required and/or suggested penalties for the repeat offender of a state's laws governing driving while intoxicated and/or driving under the influence (DWI/DUI). One such alternative is the "sober living" environment. Not all states allow this alternative; these states impose a mandatory sentence of imprisonment upon a repeat offender with no sentencing alternatives.
