Understanding Your Rights During a DWI Stop

Being pulled over on suspicion of driving while intoxicated (DWI) in Texas is a serious matter. One of the first things an officer may do after initiating a traffic stop is ask you to perform a series of roadside exercises known as field sobriety tests (FSTs). These are designed to help the officer assess whether you’re impaired and gather probable cause for a DWI arrest.

But many drivers don’t realize this important fact: you can legally refuse to take a field sobriety test in Texas. And in many cases, doing so is in your best interest.

Before making any decision during a DWI stop, it’s essential to understand your legal rights, the role of FSTs, and the consequences of refusal.

What Are Field Sobriety Tests?

Field sobriety tests are standardized physical and cognitive exercises conducted by police officers at the roadside. These tests are meant to evaluate balance, coordination, and attention—all of which can be impaired by alcohol or drugs.

The most common standardized tests include:

  • Horizontal Gaze Nystagmus (HGN): Involves tracking an object with your eyes.

  • Walk-and-Turn (WAT): Requires walking heel-to-toe in a straight line, turning, and returning.

  • One-Leg Stand (OLS): Involves standing on one leg while counting aloud.

Though officers may rely heavily on these tests to support a DWI arrest, they are not foolproof. Performance can be influenced by a range of factors, such as:

  • Fatigue

  • Medical conditions

  • Uneven surfaces

  • Nervousness

  • Poor lighting or weather conditions

These tests are subjective—and refusing to participate is not a violation of the law.

Is It Legal to Refuse a Field Sobriety Test in Texas?

Yes. In Texas, you are not legally required to perform field sobriety tests when asked by a police officer.

Field sobriety tests are voluntary, and there is no penalty under Texas law for refusing them. Unlike chemical tests (like breath or blood tests) that fall under the implied consent law, field sobriety tests are not covered by any law that mandates compliance.

Politely declining these tests may be the smartest decision you make during a DWI stop.

Why You Might Consider Refusing Field Sobriety Tests

There are several valid reasons why refusing to perform roadside tests may work in your favor:

1. FSTs Are Subjective

These tests rely on the officer’s personal observations and interpretations, which can be biased or influenced by preconceived notions. Officers often make arrests before administering the test, simply using the results to justify the arrest.

2. Medical or Physical Conditions May Affect Performance

Injuries, inner ear issues, age, weight, or neurological disorders can interfere with balance and coordination—even if the person is completely sober. An officer may misinterpret these factors as signs of impairment.

3. Even Sober Drivers Can Fail

Studies have shown that sober individuals frequently perform poorly on these tests. Nerves, stress, or poor instructions can all impact how you appear during the test, leading to a wrongful arrest.

4. Test Conditions Are Often Less Than Ideal

Sloped pavement, gravel roads, rain, or low visibility can make even a well-coordinated person struggle with tasks like walking a straight line.

5. You Don’t Want to Provide Evidence Against Yourself

The purpose of field sobriety tests is to gather evidence. Once you agree to perform them, you are giving the officer more potential justification for your arrest—and the prosecution more ammunition for court.

What Happens If You Refuse a Field Sobriety Test?

If you decline to perform the tests, the officer may still arrest you if they believe they have enough probable causebased on other observations, such as:

  • The smell of alcohol

  • Slurred speech

  • Bloodshot eyes

  • Erratic driving behavior

However, by refusing, you deny the officer additional evidence that can be used against you in court.

It’s important to remain calm and respectful when refusing. You can say something like:

“Officer, I prefer not to perform any field sobriety tests.”

This simple, polite refusal helps protect your rights while keeping the interaction from escalating.

Refusing Field Sobriety Tests vs. Chemical Tests: Know the Difference

While field sobriety tests are voluntary, refusing a breath, blood, or urine test after a lawful arrest falls under Texas’s implied consent law. Refusing a chemical test after arrest can lead to:

  • Automatic driver’s license suspension

  • Use of your refusal as evidence in court

  • A longer interlock device requirement if convicted

Make sure you understand the distinction. Refusing roadside exercises is legal and non-punitive, but refusing a breath or blood test after arrest does carry consequences.

How a Texas DWI Lawyer Can Help If You’ve Refused a Field Sobriety Test

If you refused to take field sobriety tests during a DWI stop, you may have a stronger defense than someone who performed poorly. At The Law Office of Alex Tyra, P.C., we evaluate every detail of your arrest to determine:

  • Whether the officer had reasonable suspicion to initiate the stop

  • If there was probable cause to make an arrest without FSTs

  • Whether your rights were violated during the traffic stop or arrest

  • Whether the evidence against you is sufficient or can be challenged

Even if you were arrested, refusing FSTs can make it more difficult for the prosecution to prove impairment beyond a reasonable doubt.
