How Does a DUI Become Aggravated When No One Was Hurt, But the Breath Test Was Refused?

Zak Newman Attorney at Law Feb. 16, 2026

Many people believe refusing a breath test is permissible; however, a refusal can have significant consequences. A single traffic stop in which you refuse a breath test can quickly put your license, your freedom, and your future at risk, even if you never intended to cause harm.

Legal issues that stem from refusing a breath test occur more often than you may realize. However, Zak Newman, Attorney at Law, regularly works with clients who have experienced the consequences of a breath test refusal and is committed to helping you understand how a standard DUI allegation can escalate. 

If you refused a breath test during a traffic stop and wonder what will happen next, reach out to Zak Newman, Attorney at Law, for experienced advice. Located in Chattanooga, Tennessee, the firm serves clients throughout the state, including Red Bank, East Ridge, and Collegedale.

How Does a DUI Escalate to an Aggravated DUI?

While a basic DUI charge already carries serious penalties, certain factors can elevate it to an aggravated DUI, even if no one was injured. One of the most misunderstood triggers that can escalate a DUI is refusing a breath test.

By driving on Tennessee roads, you are subject to the state's implied consent rules. These rules state that by holding a Tennessee driver's license, you agree to submit to chemical testing, such as breath tests, when requested to do so following a traffic stop. Refusing to submit to a breath test automatically triggers additional penalties that are separate from the DUI charge, and can result in a DUI charge escalating to an aggravated DUI charge.

An aggravated DUI often means steeper fines, longer license suspensions, and mandatory jail time. Many drivers assume aggravation only applies when injuries or property damage occur. Unfortunately, that’s not always the case.

What Refusing a Breath Test Really Means Under Implied Consent Laws

Tennessee operates under an implied consent law. That means by driving on public roads, you’ve already agreed to submit to chemical testing if lawfully stopped for a DUI. Refusing the breath test doesn’t make the DUI charge disappear. Instead, it leads to additional penalties. The primary consequences of refusing a breath test include:

  • Automatic license suspension: Refusing a breath test automatically triggers a mandatory license suspension that is separate from any DUI conviction.

  • Use of refusal as evidence: Prosecutors may argue that refusing a breath test suggests a consciousness of guilt.

  • Higher stakes in negotiations: Refusing a breath test can decrease your available options when seeking reduced charges.

  • Increased scrutiny by the court: Tennessee judges may view a refusal of a breath test as non-cooperative behavior.

Refusing a breath test rarely shields drivers the way they think it will. Instead, the refusal can be combined with other factors of the DUI charge to support an aggravated DUI charge. If you refused a breath test during a DUI traffic stop, speak with an experienced DUI lawyer as soon as possible before additional penalties stack up.

Factors That Can Elevate a No-Injury DUI to an Aggravated DUI

Refusing a breath test alone doesn’t automatically result in an aggravated DUI, but it can contribute to it when combined with other details from the stop. Law enforcement and prosecutors will consider the full picture, not just whether someone was injured. Some common factors that can push a case into aggravated territory include:

  • Prior DUI convictions: Past offenses significantly raise the chance of an aggravated DUI.

  • High level of impairment signs: Slurred speech, poor balance, or failed field sobriety tests.

  • Reckless or dangerous driving behavior: Speeding, swerving, or ignoring traffic signals.

  • Driving with a suspended or revoked license: Especially if tied to a prior DUI.

  • Presence of a minor in the vehicle: Even without injuries, this can carry extra weight.

When these elements appear alongside a breath test refusal, prosecutors may argue that you posed a heightened risk to others on the road. That argument is often enough to justify harsher charges or sentencing requests.

Penalties and Long-Term Consequences of an Aggravated DUI

An aggravated DUI doesn’t just mean a tougher court appearance. It can follow you for years. Tennessee law allows for enhanced penalties that extend far beyond those associated with a standard DUI charge.

The immediate consequences often include longer jail sentences, higher fines, and extended license revocation. However, the long-term impact is just as serious. Your employment opportunities, professional licenses, and even housing options can be affected by an aggravated conviction. The primary potential consequences may include:

  • Extended incarceration: Mandatory jail time increases with aggravation. Tennessee courts may have limited discretion to reduce or suspend these sentences once aggravating factors are established.

  • Longer license revocation periods: These are often paired with strict reinstatement requirements. These may include ignition interlock devices, alcohol education programs, and additional fees before driving privileges are restored.

  • Higher insurance costs: SR-22 filings and premium hikes can last for years. Some drivers also struggle to find insurers willing to offer coverage at all during this period.

  • Permanent criminal record impact: Aggravated offenses carry a heavier stigma. This can affect background checks for housing, professional licensing, or educational opportunities.

  • Restricted travel or job options: This is especially true for positions requiring a clean driving record. Certain employers may view an aggravated DUI as a disqualifying factor regardless of your job performance.

Once these penalties are imposed, undoing the damage is extremely difficult. That’s why early advocacy matters. Addressing the charge head-on can sometimes limit how aggressively prosecutors pursue aggravation, particularly when refusal is the main issue.
