Can You Refuse a Field Sobriety Test? What You Should Know

What is A field Sobriety Test?

A field sobriety test is a series of physical and cognitive exercises that law enforcement officers use during traffic stops to determine if a driver is impaired. These tests can include walking in a straight line, standing on one leg, or following an object with your eyes. The purpose is to assess coordination, balance, and focus, which can be affected by alcohol or drugs.

Many drivers assume they must take these tests, but in Missouri, they are voluntary. Refusing, however, doesn’t mean the investigation will be over. You may still be arrested for other probable cause or required to take a breathalyzer. Knowing your rights can help you make informed decisions when interacting with law enforcement.

At The Law Offices of Brian J. Cooke, we help drivers navigate DUI-related legal matters, including decisions about field sobriety tests. We guide clients through their options, explain how refusals can impact their case, and provide representation if charges arise. Our team works to protect our clients’ rights and build strong legal strategies to achieve a fair outcome.

Understanding Field Sobriety Tests

Field sobriety tests are assessments used by law enforcement to evaluate a person’s level of intoxication. These tests help officers determine whether someone is impaired and may include several standardized exercises. A common test is the Horizontal Gaze Nystagmus (HGN), where a police officer checks for involuntary jerking of the eyes as they follow a moving object.

Other tests include the Walk-and-Turn and the One-Leg Stand. In the Walk-and-Turn, individuals are asked to walk in a straight line, turn, and return in the same manner. The One-Leg Stand involves standing on one leg while counting aloud. These tests aim to assess balance, coordination, and the ability to follow instructions, often impaired by alcohol consumption.

The National Highway Traffic Safety Administration (NHTSA) has standardized these tests to ensure consistency in their application. Nonetheless, participating in these tests is not mandatory, and their accuracy has been a controversial debate.

These tests are reliable but not foolproof. Factors like fatigue, medical conditions, and physical abilities can affect the outcomes. Despite their limitations, they remain a tool for officers to gauge potential intoxication on the spot.

Can You Refuse a Field Sobriety Test in Missouri?

It’s crucial to know that field sobriety tests are not mandatory in Missouri, and you can refuse them without any penalties. However, refusing a field sobriety test may not be the end of your encounter with law enforcement.

Refusing a field sobriety test during a traffic stop might lead to an immediate DUI arrest. Officers need only probable cause to take this action, such as erratic driving, the smell of alcohol, or slurred speech. They may also request a chemical test, which can’t be refused without legal penalties. Under Missouri’s implied consent law (RSMo § 577.020), refusing a chemical test results in a one-year license revocation and other penalties.

Prosecutors can argue that your refusal suggests you were trying to hide impairment. While it doesn’t prove guilt, a jury may view it negatively.

If you are wondering what could potentially protect you if refusing field sobriety tests doesn’t, the answer is exercising your right to remain silent and consulting an attorney. We have a long track record of successfully handling DWI cases, including reducing DWI to reckless driving and getting charges dismissed altogether.

Commercial Drivers and Field Sobriety Tests

Commercial drivers face stricter regulations and enhanced scrutiny during traffic stops. When pulled over, CDL holders must navigate additional complexities regarding field sobriety tests. While you can still refuse these tests as a commercial driver, the consequences may be more severe for your commercial driving privileges.

The Federal Motor Carrier Safety Administration (FMCSA) maintains lower blood alcohol thresholds for commercial drivers. Even without a conviction, refusing field sobriety tests can trigger administrative actions against your CDL. Your employer may also face scrutiny or liability issues if you’re arrested while operating a commercial vehicle.

Commercial drivers should understand that refusing field sobriety tests doesn’t eliminate the possibility of other testing methods. Officers may still pursue chemical testing, which carries mandatory penalties under implied consent laws. The decision to refuse requires careful consideration of both immediate and long-term career implications for professional drivers.

What to Say When Refusing Field Sobriety Tests

Knowing how to properly refuse field sobriety tests can protect your legal position while maintaining respect for law enforcement. When an officer requests you perform these tests, you can politely state: “I respectfully decline to perform field sobriety tests and would like to exercise my right to remain silent.”

Avoid providing detailed explanations about why you’re refusing, as additional statements can be used against you later. Keep your response simple and clear. You might also add: “I would like to contact my attorney” to establish your intent to seek legal counsel.

Remember that your tone and demeanor matter during this interaction. Remaining calm, respectful, and cooperative in your refusal helps prevent escalation while preserving your rights. Document the interaction mentally, noting the officer’s behavior, questions asked, and your responses for later discussion with your attorney.

What Happens Immediately After Refusing Field Sobriety Tests

After refusing field sobriety tests, officers will likely continue their investigation through other means. They may observe your behavior more closely, looking for signs of impairment such as bloodshot eyes, slurred speech, or the odor of alcohol. This observational evidence can still provide probable cause for arrest.

The officer may request a preliminary breath test (PBT), which is also voluntary in Missouri and separate from post-arrest chemical testing. Your refusal of the field sobriety test doesn’t prevent the officer from making other requests or observations during the stop.

If arrested, you’ll be transported to a police station or testing facility for chemical testing under Missouri’s implied consent law. At this point, refusing chemical tests carries automatic license suspension and other penalties. The field sobriety test refusal becomes part of the overall evidence package that prosecutors may use to build their case against you.

Passing Field Sobriety Tests Does Not Prevent Arrest

Many drivers believe that successfully completing field sobriety tests will end their DUI investigation, but this isn’t necessarily true. Officers can still arrest you based on other evidence of impairment, even if you perform well on these tests.

Chemical test results, officer observations, driving patterns, and other factors all contribute to the arrest decision. Field sobriety tests are just one tool in the officer’s assessment arsenal. Medical conditions, nervousness, fatigue, or environmental factors can affect test performance, leading to false indicators of impairment.

Additionally, officers may interpret test results subjectively, finding “clues” of impairment even in relatively normal performance. This subjective nature is one reason why field sobriety test results are often challenged in court. Understanding that passing these tests doesn’t guarantee freedom from arrest helps you make more informed decisions during traffic stops.

Legal Consequences for Chemical Test Refusal

While field sobriety tests are voluntary, chemical tests administered after arrest carry significant legal consequences if refused. Missouri’s implied consent law creates an automatic administrative penalty structure for chemical test refusal, separate from any criminal charges.

First-time refusal results in a one-year license revocation, while repeat refusals within five years can lead to longer suspension periods. These administrative actions occur regardless of whether you’re ultimately convicted of DUI charges in criminal court.

The refusal can also be used as evidence in criminal proceedings, with prosecutors arguing that refusing chemical testing indicates consciousness of guilt. However, experienced DUI attorneys can challenge this inference and present alternative explanations for refusal. Understanding the distinction between voluntary field sobriety tests and mandatory chemical tests is crucial for making informed decisions during DUI investigations.

Defenses and Legal Strategies for Field Sobriety Test Cases

Refusing field sobriety tests can be used against you in court to infer guilt, and your attorney must challenge that effectively. As part of a comprehensive DWI defense strategy, your lawyer may use the following defenses:

  • Medical conditions such as balance issues can affect performance on sobriety tests. People may fail these tests for reasons unrelated to intoxication. Using medical documentation to highlight these conditions can be a strong defense. 
  • Field sobriety tests are voluntary, and unlike chemical tests, they are not legally required in Missouri. Your attorney can argue that refusing does not indicate guilt but rather an understanding of your rights.

Beyond field sobriety test-related defenses, your attorney may also use general DWI defenses. 

  • Unlawful stops occur when officers lack reasonable suspicion, potentially challenging the entire case. 
  • Faulty breath or blood tests due to improper calibration, contamination, or medical conditions like GERD can lead to inaccurate BAC results.
  •  Lack of probable cause means that if the officer lacked a valid reason to stop you initially, any evidence, including your refusal, could be suppressed.

Building a strong defense requires experience and knowledge. That’s why working with a dedicated DUI lawyer is valuable. Together, we can face the charges and pursue a path that aims to protect your rights and future.
