Field sobriety tests are standard tools used by police to assess if someone is driving under the influence of drugs or alcohol. But these tests are not perfect, and neither are the humans administering them. Let’s dive into why these tests have vulnerabilities and how challenging their results can help you.
Weak points of field sobriety tests
Field sobriety tests include three standardized tests. While they are designed to determine if someone is impaired, there are multiple vulnerabilities associated with each test:
- Walk-and-turn test: This test requires you to walk in a straight line, turn and walk back. It sounds simple, but many factors can affect your performance. Uneven ground, poor lighting or even nervousness can cause you to stumble.
- Horizontal gaze nystagmus: In this test, an officer checks your eye movements. They look for jerking movements as you follow a moving object. However, many medical conditions and even fatigue can cause similar eye movements.
- One-leg stands: These tests require you to stand on one leg or touch your nose with your eyes closed. Balance can be affected by many things, including inner ear problems, age or even the type of shoes you’re wearing.
Not only are there vulnerabilities with the tests, but police officers can make mistakes when administering them. They can give improper instructions, or there could be language barriers. When assessing performance, officers can misinterpret nervousness as intoxication or overlook other factors affecting performance.
Further, personal biases can influence officers’ use, administration and interpretation of these tests.
Challenging the results
Challenging the results of field sobriety tests can be crucial if you are facing drunk driving charges. You can work with an attorney to dispute the results and contest charges to potentially get them reduced or dropped. Here are some steps to consider:
- Document everything: Note the conditions during the test, such as lighting and ground surface.
- Talk to a lawyer: An attorney can help you understand rights and defense strategies.
- Gather evidence: Medical records or witness statements can support your case.
Challenging the results can make a significant difference in the outcome of your case.
Field sobriety tests are not foolproof, and neither are the humans who administer them. Knowing their weaknesses and reasons for questioning the results can help you understand your legal options and next steps.
