Can You Refuse a Field Sobriety Test in Utah?

 Posted on February 10, 2026 in DUI

You can refuse a field sobriety test during a DUI stop in Utah. However, refusing does not always mean you avoid consequences. Police officers may still arrest you based on other signs of impairment, and your decision can affect what happens next in your case.

If you are facing a DUI charge, understanding your rights can help you make informed decisions. Speaking with Salt Lake City, UT DUI defense lawyers as early as possible can help you protect those rights.

What Is a Field Sobriety Test?

A field sobriety test is a group of physical and mental exercises police use during a traffic stop. These tests help officers decide whether a driver may be impaired.

Common examples include walking in a straight line, standing on one leg, or following an object with your eyes. These tests are designed to check balance, coordination, and attention.

It is important to understand that these tests are subjective. The officer is using personal judgment when deciding whether you passed or failed.

Are Field Sobriety Tests Required Under Utah Law?

Field sobriety tests are usually voluntary in Utah. This means you can decline to participate. There is no separate criminal penalty just for refusing these roadside exercises.

However, Utah’s implied consent law, found in Utah Code § 41-6a-520, applies to chemical testing such as breath, blood, or urine tests after a lawful arrest. Implied consent means that by driving in Utah, you have already agreed to submit to chemical testing if police have probable cause.

Unlike refusing a field sobriety test, refusing a chemical test can trigger serious consequences, including automatic license suspension.

Why Might Someone Refuse a Field Sobriety Test?

Drivers refuse these tests for many reasons, including:

• Injuries that limit mobility
• Medical conditions affecting balance
• Anxiety during roadside testing
• Poor weather or uneven pavement
• Fear of being judged unfairly

Even small factors can affect performance, which is why some drivers choose not to participate.

Can Police Arrest You if You Refuse a Field Sobriety Test in Utah?

Refusing a field sobriety test does not prevent an arrest. Officers look at the total situation when deciding whether probable cause exists. That means that even without field sobriety testing, they could decide there is enough evidence for a reasonable person to believe a crime may have occurred.

Police may rely on observations such as the smell of alcohol, slurred speech, bloodshot eyes, or erratic driving. If these signs are present, an arrest can still happen.

What Happens After a DUI Arrest in Utah?

After an arrest, officers typically request a chemical test. Drivers are considered legally impaired at 0.05 percent or higher, which is lower than the limit in many other states.

Possible consequences after a DUI arrest may include:

• Driver’s license suspension
• Fines and court costs
• Required education or treatment programs
• Installation of an ignition interlock device
• Possible jail time

Is Refusing a Field Sobriety Test the Right Choice?

There is no single answer that fits every situation. Refusing may limit the amount of physical test evidence available. However, it does not stop an officer from building a case using other observations.

Because every traffic stop is different, it is wise to focus on staying calm and respectful. Avoid arguing with the officer or making sudden movements.

The most important step is seeking legal guidance afterward. A defense attorney can review the stop and determine whether law enforcement followed proper procedures.
