What are Field Sobriety Tests?
Field sobriety tests in Illinois are procedures used by law enforcement officers to assess a driver's level of impairment. These tests are designed to evaluate balance, coordination, and the ability to perform tasks requiring divided attention, which are typically compromised by alcohol or drug consumption.
Types of Standardized Field Sobriety Tests
There are three primary standardized field sobriety tests recognized in Illinois:
- Horizontal Gaze Nystagmus (HGN) Test
- Walk-and-Turn Test
- One-Leg Stand Test
These tests are approved by the National Highway Traffic Safety Administration and are the most commonly used methods to determine impairment.
Legal Implications of Refusing Field Sobriety Tests
In Illinois, drivers are not legally obligated to submit to field sobriety tests. However, refusal often leads to an arrest on suspicion of DUI, particularly if other signs of impairment are evident. It's important to understand the differences in legal consequences between refusing a field sobriety test and other tests, like breathalyzers, as outlined on our DUI page.
Implied Consent and Field Sobriety Tests
Illinois law operates under an 'implied consent' principle. By holding an Illinois driver's license, you have implicitly agreed to submit to chemical and field sobriety tests if pulled over under suspicion of DUI. The nuances of this consent are further discussed in our Illinois DUI Defense section.
Using Field Sobriety Tests in Court
Although not foolproof, field sobriety tests are considered reliable indicators of impairment and are frequently used as evidence in DUI cases. Their administration and the results can significantly impact the course of a DUI case, as detailed in our DUI Defense Strategies section.

Conducting Field Sobriety Tests: What to Expect
When a law enforcement officer in Illinois suspects a driver of being impaired, they may conduct field sobriety tests. The procedure for each test varies:
- Horizontal Gaze Nystagmus (HGN) Test: This involves following an object with the eyes to observe nystagmus (jerking of the eye), which becomes pronounced under impairment.
- Walk-and-Turn Test: This evaluates a driver's ability to complete tasks, requiring them to walk in a straight line and turn on one foot.
- One-Leg Stand Test: The driver must stand with one foot approximately six inches off the ground and count aloud until instructed to put their foot down.
The officer's observation and the driver's performance during these tests contribute to the decision to arrest for DUI.
Reliability of Field Sobriety Tests
While standardized field sobriety tests are widely used, their reliability can be influenced by various factors, including the driver's physical condition, nervousness, and even the environment in which the tests are conducted. This aspect is critical in Illinois DUI Court Process and can be a point of contention in DUI Record Expungement.
Field Sobriety Tests and DUI Defense
Refusal to perform field sobriety tests does not carry the same consequences as refusing a chemical test, such as a breathalyzer. However, refusal can still lead to DUI charges, necessitating a robust defense strategy. Legal guidance in such scenarios is essential, as discussed on our Role of DUI Lawyers page.

Impact of Field Sobriety Test Results in DUI Cases
Field sobriety test results can significantly influence a DUI case in Illinois. If the tests suggest impairment, they can be used as probable cause for arrest and as evidence in court. However, the subjective nature of these tests allows for potential challenges in their validity and administration.
Challenging Field Sobriety Tests in Court
Defense strategies often involve questioning the:
- Accuracy of the Tests: Highlighting the inherent flaws in the tests, such as the effects of medical conditions or external factors, can undermine their reliability.
- Proper Administration: Defense may argue that the tests were not conducted according to the standardized procedures, affecting the results.
- Officer's Interpretation: The subjective nature of the officer's judgment in interpreting the results can be contested.
These challenges are crucial in Illinois DUI Defense Attorney strategies and can be pivotal in Illinois Sentencing Mitigation.
