Can I Refuse a Breathalyzer? What Utah Drivers Need to Know

If you’re pulled over for suspected DUI, one of the first questions that may cross your mind is:

“Can I refuse a breathalyzer?” While refusing might seem like a way to protect yourself, Utah has strict implied consent laws — and refusing a chemical test can lead to serious consequences.

Here’s what you need to know before making that decision.

Utah’s Implied Consent Law

Utah law states that anyone who operates a vehicle in the state automatically gives implied consent to chemical testing (breath, blood, or urine) if lawfully arrested for DUI.

This means you can refuse a breathalyzer, but the consequences can be severe.

What Happens If You Refuse a Breathalyzer in Utah?

Refusing a chemical test triggers automatic penalties, separate from the DUI charge itself.

1. Automatic License Suspension

A refusal results in:

• 18-month license suspension for a first refusal

• 36-month suspension for a second refusal

This is significantly harsher than the suspension for taking the test and failing.

2. Additional Criminal Charges (Refusing a Chemical Test).

• Usually a Class B Misdemeanor for first refusal

• Usually a Class A Misdemeanor for second refusal

• Usually a 3rd Degree Felony for third or subsequent refusal

3. Higher Court Fines

By statute, the mandatory minimum court fine for Refusing a Chemical Test is higher than the fee imposed for a DUI.

4. Mandatory Ignition Interlock Device (IID)

Refusal often leads to mandatory IID installation if the DUI charge moves forward, even for first-time offenders.

5. Use of Refusal as Evidence

Prosecutors can argue that refusing the test suggests you were trying to hide impairment.

6. Forced Blood Draw (in some cases)

Officers can obtain a warrant for a blood test, meaning refusal may only delay (not prevent) chemical testing — and you can still be criminally charged with Refusing a Chemical Test.

Can Refusing a Breathalyzer Help Your Case?

In most cases, no.Because Utah punishes refusal more harshly than a failed test, refusing can:

• Make penalties worse

• Complicate your defense

• Trigger longer suspensions

• Lead to additional charges

However, every situation is different, and an attorney can help determine the best way to proceed after a refusal.

Is It Better to Take the Test?

For many people, complying with the test results in fewer penalties than refusing, especially for first-time offenders. But this decision depends on:

• Your BAC level

• The number of substances in your system

• Prior DUI history

• Circumstances of the stop

• Whether the officer followed proper procedures

An experienced DUI attorney will review all of this to build the strongest defense.

What to Do If You Have Already Refused a Test

If you refused a breathalyzer in Utah:

• You have 10 days to request a Driver License Division (DLD) hearing.

• You should contact an attorney immediately to protect your driving privileges.

• Your lawyer can challenge the suspension, review the stop, and look for procedural errors.

Acting quickly is the key to improving the outcome of your case.
