Refusing a Field Sobriety Test in Texas: What You Need to Know

Being stopped on suspicion of driving while intoxicated can be a stressful and confusing experience. One of the most common questions drivers have is whether they are required to perform field sobriety tests, and what happens if they refuse.

Understanding how these tests work and what your rights are can help you make informed decisions if you are ever in this situation.

What Is a Field Sobriety Test in Texas?

A field sobriety test is a series of roadside exercises that a law enforcement officer may ask a driver to perform during a traffic stop. These tests are used to help the officer assess whether a person may be impaired by alcohol or drugs.

Field sobriety tests do not measure blood alcohol concentration. Instead, they rely on the officer’s observations of a person’s balance, coordination, and ability to follow instructions.

In Texas, officers are trained to administer three standardized field sobriety tests:

• Horizontal Gaze Nystagmus, which evaluates eye movement
• Walk and Turn, which tests balance and coordination
• One Leg Stand, which measures balance and divided attention

Although these tests are standardized, they are still based on human observation and interpretation.

Are You Required to Take a Field Sobriety Test?

No. In Texas, field sobriety tests are voluntary.

There is no law that requires a driver to perform roadside exercises during a traffic stop. An officer may request that you participate, but you have the right to decline.

However, refusing to perform these tests does not end the investigation. In Texas, an officer is not required to offer a chemical test when conducting a DWI investigation. In certain situations, an officer may request a preliminary breath test (PBT) at the roadside, but this is not a right or requirement.

What Happens If You Refuse?

Refusing a field sobriety test does not carry an automatic penalty such as a fine or license suspension. Unlike certain chemical tests such as breathalyzers or blood tests, there is no direct legal consequence for declining roadside exercises.

That said, there are still important considerations.

An officer may continue the investigation based on other observations, including driving behavior, physical appearance, and any statements made during the stop. If the officer believes there is probable cause, you may still be arrested.

In addition, a refusal may be used as evidence in court. A prosecutor may argue that a person declined the test because they believed they would not perform well. Each case is evaluated based on the totality of the circumstances, not just whether a test was performed.

Refusing a Chemical Test Is Different

It is important to distinguish between field sobriety tests and chemical tests such as breath or blood tests.

After an arrest, Texas law operates under an implied consent framework. This means that by driving on public roads, a person is considered to have consented to chemical testing under certain circumstances.

Refusing a breath or blood test after arrest can lead to administrative penalties, including a driver’s license suspension. Field sobriety tests, by contrast, remain voluntary and do not carry the same automatic consequences.

How Can You Decline a Field Sobriety Test?

If you choose not to perform field sobriety tests in Texas, it is generally best to communicate clearly and respectfully.

Examples of simple responses you might choose to use include:

• I respectfully decline to perform the test.
• I would prefer not to perform any tests.

It is important to avoid arguments or lengthy explanations. Fewer words are often better. Traffic stops are frequently recorded, and statements made during the encounter may later be reviewed in court.

What Are You Required to Provide During a Traffic Stop?

Texas law does require drivers to provide certain information during a traffic stop.

A driver must provide a valid driver’s license and proof of active insurance for the vehicle being driven. A person is also required to identify themselves if lawfully arrested. Providing false information can lead to criminal charges.

However, a driver is generally not required to answer investigatory questions such as whether they have been drinking or where they are coming from. A person has the right to decline to answer questions that may be incriminating.

The passenger of a vehicle is typically not required to identify themselves during a routine traffic stop, however, providing false identifying information is considered an offense.

Alternative or Non Standardized Tests

In addition to the standardized field sobriety tests, an officer may ask a driver to perform other exercises.

These may include reciting the alphabet forwards or backwards, counting backwards or touching a finger to the nose. These are considered non standardized tests. They do not have the same validation or scoring criteria as the standardized tests and can be even more subjective.

Like the standardized tests, these exercises are voluntary.

How Reliable Are Field Sobriety Tests?

Field sobriety tests are based on observation, which means they can be affected by a variety of factors unrelated to alcohol or drug use.

These factors may include medical conditions that affect balance or vision, injuries that might include head injuries from an auto accident, fatigue or stress, uneven pavement or poor lighting, or footwear such as high heels or boots.

For example, a person who has just been involved in a crash may be disoriented or injured, which can affect their performance on these tests. A person wearing high heels might stumble on uneven asphalt, which would affect their balance.

Because of these variables, the reliability of field sobriety tests is often examined closely in court. Video evidence of performance during these tests are often used in criminal DWI trials.

Are Field Sobriety Tests Recorded?

In many cases, field sobriety tests are recorded using police dash cameras or body cameras. These recordings can show how the tests were administered, the conditions at the scene, and how a person performed.

However, there is no universal law requiring that field sobriety tests be recorded in every case. Video evidence can play an important role. It allows a judge or jury to evaluate the interaction directly rather than relying only on an officer’s report.

Medical Conditions and On Camera Statements

Medical conditions can affect a person’s ability to perform field sobriety tests. Conditions affecting balance, coordination, or vision may create results that appear similar to impairment.

In some situations, a person may choose to mention a medical condition at the time of the stop. Doing so may create a real time record if the interaction is recorded. In other cases, the issue may be raised later in court through medical records or expert testimony.

Each approach has different considerations. Statements made at the scene may be recorded and reviewed later, while issues raised later may be subject to questions about timing. Consistency between the two can become important in a legal defense.
