Can I Refuse a Breathalyzer in Utah?

Glen Neeley defends breath test refusal cases across Utah. The short answer is that you can refuse, but which test you refuse changes everything. Declining the roadside portable breath test carries no implied consent penalty. Refusing the post-arrest chemical test triggers an automatic 18-month license revocation under Utah Code 41-6a-521, and that revocation lands even if the criminal charge is later reduced or dismissed.

Glen has defended Utah DUI cases since 1998. His training includes the Borkenstein Course on alcohol testing and highway safety, Intoxilyzer operator certification, and a faculty position at the National College for DUI Defense. That background is what lets him challenge how a refusal was obtained and what the state claims it proves.

Two Different Breath Tests, Two Different Rules

Not every breath test during a Utah DUI stop is the same, and the difference decides what a refusal actually costs you.

The PBT helps an officer build probable cause for an arrest. Declining it does not trigger implied consent penalties, but the officer can still arrest you on other observations: the odor of alcohol, slurred speech, field sobriety test performance, or erratic driving.

The evidential test comes after a lawful arrest and is the one governed by Utah’s implied consent law, Utah Code 41-6a-520. That is the refusal with administrative consequences attached.

What Refusing the Evidential Test Costs You

The revocation is administrative. The Driver License Division imposes it separately from criminal court, and it takes effect even if the DUI charge is reduced or dismissed entirely. Set against the 120-day suspension that follows a first conviction, an 18-month license revocation is the far heavier consequence.

The enhancement is the part most people miss. Under Utah Code 41-6a-521, a prior conviction under the DUI statute (Utah Code 41-6a-502) or a prior DUI-related license sanction within the previous 10 years raises a first-time refusal from 18 months to 36. It does not have to be a prior refusal. A driver whose only prior is a DUI conviction still faces the 36-month revocation.

Refusing also hands the prosecution an argument, that the refusal shows consciousness of guilt. That argument can be challenged, but it is one more piece of evidence in front of a judge or jury.

The 10-Day Deadline to Save Your License

You have 10 calendar days from the date the notice of revocation is served, which the officer usually hands you at the arrest, to request a Driver License Division hearing. Miss it and you waive the right to contest the revocation, and the 18-month suspension takes effect automatically. It is one of the shortest deadlines in Utah DUI law.

The DLD hearing is a separate proceeding from the criminal case, heard by a hearing officer rather than a judge. The hearing officer weighs three things:

• Whether the arresting officer had reasonable grounds for the arrest.
• Whether the officer properly advised you of the consequences of refusal.
• Whether you actually refused the test.

Glen represents clients at DLD hearings throughout Utah and uses the hearing twice over: to protect the license, and to put the arresting officer under oath early, which can produce testimony that helps the criminal defense. Winning the hearing prevents the administrative revocation altogether, which matters in a state where daily life depends on being able to drive.

When a Refusal Can Be Challenged

A refusal is rarely as clean as the police report makes it look. Several things affect whether it holds up:

• The officer must have had reasonable grounds for the DUI arrest. If the arrest was unlawful, the implied consent obligation may not apply.
• The officer must advise you of the consequences of refusal before requesting the test. An incomplete, confusing, or missing admonition can make the refusal challengeable.
• The request must be for a lawful chemical test. A demand made without proper authority may not carry the standard penalties.
• Medical conditions, language barriers, or genuine confusion about what was being asked all bear on whether the refusal was knowing and voluntary.

Glen reviews the body camera footage, the officer’s report, and the circumstances of every refusal case. What an officer writes up as a refusal does not always meet the legal definition of one.

Refuse or Submit? What Actually Changes

This decision gets made at the station, without time to call a lawyer, so the useful question is what each choice actually changes.

• If your alcohol concentration is well above the limit, refusing denies the prosecution a specific number. It does not deny them the refusal itself, the officer’s observations, your field sobriety test performance, or a blood draw obtained by warrant. Utah law lets officers seek a warrant for blood after a breath test refusal, so refusing does not guarantee there will be no chemical evidence.
• If your alcohol concentration is near or below the .05 limit, submitting can produce a result that does not support the charge. Refusing in that situation trades a potentially favorable number for a guaranteed 18-month revocation.

Every case turns on facts you may not have understood in the moment. What matters now is how the decision you made gets defended.

How Glen Neeley Defends Breath Test Refusal Cases

Refusal cases run on two tracks at once, and Glen works both:

• The Driver License Division hearing, challenging reasonable grounds for the arrest, the lawfulness of the arrest itself, and whether the implied consent admonition was properly given.
• The criminal case, addressing how the prosecution uses the refusal as evidence of guilt.

His training includes the Borkenstein Course on alcohol testing and highway safety, Intoxilyzer operator certification, and a faculty position at the National College for DUI Defense. That lets him explain to a judge or jury what the state’s evidence does and does not establish. The absence of a chemical test result is not proof of impairment.
