Drug and alcohol tests used by law enforcement agencies vary from state to state, and in many cases, from jurisdiction to jurisdiction within states. However, they do provide law officers with a generally reliable means of determining if an individual has consumed alcohol beyond the legal limit to operate a motor vehicle. The purpose of this blog post is to make you aware of the following two Oregon DUII tests, both of which are commonly used throughout the state.
Field Sobriety Tests (FSTs)
FSTs are standardized tests that allow an officer to determine if an individual is under the influence of alcohol or drugs. FSTs are used to help determine probable cause to administer a Breathalyzer Test. Most people have seen police administer these common tests on television shows. They are designed to challenge a driver’s ability to perform simple tasks, such as touching one’s finger to his or her nose. Drivers who fail these tests often demonstrate an inability to follow instructions, a significant loss of balance, or other indications of impairment. Three typical tests include: the Horizontal Gaze Nystagmus (HGN), Walk and Turn (WAT), and the One Legged Stand (OLS). Just as in many sobriety tests, your refusal to perform a FST can be used against you in court.
Breathalyzer Tests
These tests are used to determine the percentage of alcohol in the blood, also known as the Blood Alcohol Content (BAC) by measuring a sample of a driver’s breath. There are several types of breathalyzer test devices used by law enforcement. Among them, the Intoxylizer Test is the most commonly used in Oregon. The Intoxylizer can be very accurate, however, not necessarily 100% precise.
Level of Intoxication
Oregon law provides that it is not unlawful for a person to drive a vehicle after having consumed intoxicating liquor. It is unlawful, however, for that person to drive a vehicle if the person is under the influence of intoxicating liquor and/or controlled substances. Therefore, to be convicted of a DUII, you do not have to be drunk or intoxicated. “Under the influence of intoxicating liquor” means that a person’s physical or mental faculties were adversely affected by the use of intoxicating liquor to a noticeable or perceptible degree.
“Under the influence of intoxicating liquor” includes not only the well-known and easily recognized conditions and degrees of intoxication, but also any abnormal mental or physical condition that results from consuming intoxicating liquor that deprives a person of that clearness of intellect or control that the person would otherwise possess. This means that while one’s BAC is related to a driver’s impairment, avoiding a DUII is not as simple as registering a BAC below .08. The relationship between drinks consumed, and one’s BAC, varies greatly among individuals. Therefore, even if you know your BAC, it should not be relied upon when deciding whether or not to drive. Law enforcement officials know this fact, and are permitted to use their own judgment to evaluate whether a driver is “adversely affected to a noticeable or perceptible degree.” This means that it is possible to be charged with a DUII, and have a BAC below .08%.
Why You Want an Experienced DUII Lawyer on Your Side
Law officers are required to follow very specific procedures when charging an individual with violating DUII law. Any deviation from these stated rules (such as, how a question is phrased by an officer, how probable cause was determined, how your Miranda Rights were read, or the misuse or malfunction of testing equipment) potentially help in the defense of a DUII charge. Our experts at Gilroy & Napoli are fully knowledgeable of these rules, and will ensure that your rights are represented to the fullest extent of the law.
