Field Sobriety Tests: What They Are and How They Work
Field sobriety tests are a series of physical and cognitive tests administered by law enforcement officers to determine whether a person is driving under the influence of alcohol or drugs. These tests are designed to assess a driver’s balance, coordination, and cognitive function, all of which can be impaired by intoxication. Wish to know more about the topic?

During a field sobriety test, an officer may ask a driver to perform tasks such as walking in a straight line, standing on one leg, or following a moving object with their eyes. The officer then observes the driver’s ability to perform these tasks and notes any signs of impairment.
Types of Field Sobriety Tests
There are three standardized field sobriety tests that are commonly used by law enforcement officers: the Horizontal Gaze Nystagmus (HGN) test, the Walk-and-Turn test, and the One-Leg Stand test. The HGN test involves observing the driver’s eye movements as they track a moving object, while the Walk-and-Turn test and One-Leg Stand test assess the driver’s balance and coordination.
In addition to these standardized tests, an officer may also use non-standardized tests to gather further evidence of impairment, such as asking a driver to recite the alphabet or count backwards.
Understanding Breathalyzer Results
After administering field sobriety tests, an officer may use a breathalyzer to measure a driver’s blood alcohol concentration (BAC). A breathalyzer is a device that analyzes a person’s breath to estimate their BAC, which is the percentage of alcohol in their bloodstream. The legal limit for BAC in most states is 0.08%, meaning that a driver with a BAC of 0.08% or higher is considered legally intoxicated.
It’s important to understand that breathalyzer results can be influenced by various factors, including the type of alcohol consumed, the rate of consumption, and the individual’s metabolism. As a result, breathalyzer readings may not always accurately reflect a person’s level of impairment.
Challenging Field Sobriety Tests and Breathalyzer Results
If you have been charged with driving under the influence based on field sobriety tests and breathalyzer results, it’s important to understand that these tests are not foolproof. There are many factors that can lead to inaccurate results, and a skilled attorney can help challenge the validity of the tests in court.
An experienced defense attorney may question the administration of the field sobriety tests, the officer’s qualifications, or the accuracy of the breathalyzer device. In some cases, the attorney may be able to have the results of the tests suppressed or dismissed, leading to a reduction or dismissal of the DUI charges.
In conclusion, understanding field sobriety tests and breathalyzer results is crucial if you find yourself facing DUI charges. By being informed about the purpose and limitations of these tests, and seeking the guidance of a knowledgeable attorney, you can better navigate the legal process and protect your rights.
