Field Sobriety Tests: What You Need to Know, Orlando DUI attorney

Updated: Aug 23, 2023

When it comes to ensuring road safety and preventing accidents caused by impaired driving, law enforcement agencies rely on a range of tools and techniques. One of the primary tools in their arsenal is the administration of field sobriety tests. These tests are designed to assess a driver's physical and cognitive abilities to determine whether they are under the influence of alcohol or drugs. However, understanding your rights and the accuracy of these tests is crucial. In this blog post, we will delve into the different types of field sobriety tests, their accuracy, and what you need to know if you find yourself facing these tests. It's important to hire an Orlando DUI attorney as soon as possible.


Types of Field Sobriety Tests:

  1. Horizontal Gaze Nystagmus (HGN): This test involves tracking a moving object, usually a pen or flashlight, with your eyes while keeping your head still. Nystagmus, which is an involuntary jerking of the eyes, is more pronounced when a person is intoxicated. Officers look for signs of nystagmus to assess impairment.

  2. Walk and Turn: In this test, the individual is asked to walk a straight line, taking nine heel-to-toe steps, then pivot and return in the same manner. The officer is observing for balance issues, an inability to follow instructions, and an inability to walk a straight line.

  3. One-Leg Stand: In this test, the person is required to stand on one leg while raising the other leg about six inches off the ground. They must then count out loud until instructed to stop. The officer assesses for swaying, hopping, or the inability to maintain balance.

Accuracy and Limitations:


While field sobriety tests are intended to gauge impairment, they are not foolproof and have limitations that can affect their accuracy. Environmental factors, medical conditions, and even nervousness can all contribute to false positives. Additionally, officers may not administer the tests consistently, which could lead to inaccurate results. Studies have shown that the accuracy rates for individual tests can vary widely, with HGN being considered the most accurate among them.


Your Rights During Field Sobriety Tests:


It's essential to be aware of your rights if you're asked to undergo field sobriety tests. Here's what you need to keep in mind:

  1. You Have the Right to Refuse: Generally, you have the right to refuse to take a field sobriety test. However, refusal may lead to administrative penalties such as license suspension, as implied consent laws vary from place to place.

  2. Be Courteous: If you decide to take the tests, remember that politeness and cooperation are essential. Being rude or uncooperative can work against you in a legal setting.

  3. You Can Request Legal Representation: If you are arrested, you have the right to an attorney. It's usually a good idea to seek legal advice before submitting to any further testing or questioning.

  4. Observe the Testing Conditions: If you believe that the conditions during the tests were unfavorable (e.g., uneven ground, poor lighting), it's worth noting that these factors could impact your performance.

In Conclusion:


Field sobriety tests play a significant role in identifying potentially impaired drivers on the road. However, their accuracy can be influenced by various factors, and understanding your rights when faced with these tests is vital. Remember that cooperation and knowledge of your rights can help you navigate the situation effectively. If you find yourself in such a situation, remain calm, and if needed, seek legal advice promptly.
