Our Defense Strategy in Indiana Felony DUI Cases

Felony OWI charges expose you to far-reaching consequences that extend well beyond the courtroom. Convictions can result in incarceration, long-term loss of driving privileges, and a permanent criminal record. Many defendants also face job loss, difficulty securing housing, increased insurance costs, and damage to professional licenses or commercial driving status.

For those with families, felony DUI allegations can disrupt financial stability and personal relationships. Because these cases often involve complex evidence and heightened scrutiny, early legal guidance is critical to protecting rights and limiting exposure.

Our firm takes a methodical, evidence-focused approach to felony DUI defense. These cases often hinge on technical details: 

  • Chemical testing procedures
  • Prior conviction analysis
  • Accident reconstruction
  • Law enforcement conduct

We carefully examine whether prior OWI convictions were properly alleged, whether enhanced charge elements can be challenged, and whether constitutional or procedural violations occurred.

Attorney Chuck Rathburn’s extensive training in breath testing systems, standardized field sobriety testing, and alcohol-related evidence allows our firm to analyze the scientific foundations of the State’s case. When appropriate, we pursue suppression of unlawfully obtained evidence, reduction of charges, or dismissal of enhancement allegations.

What Is a Felony DUI in Indiana?

In Indiana, an OWI offense may be charged as a felony under several circumstances, including:

  • A prior OWI conviction within the past seven years
  • OWI resulting in serious bodily injury
  • OWI resulting in death
  • Certain repeat-offense scenarios involving prior felony OWI convictions

Felony OWI charges are classified under Indiana’s felony levels, most commonly Level 6 or Level 5, depending on the facts alleged.

Penalties for Felony DUI / OWI

Potential penalties vary based on the level of the felony and the specific allegations, but may include:

  • Level 6 felony OWI: Up to two and a half years in prison and fines up to $10,000
  • Level 5 felony OWI: Up to six years in prison and fines up to $10,000

Additional consequences may include extended license suspension, probation, participation in alcohol-related treatment programs, and ignition interlock device requirements. Aggravating factors can significantly increase sentencing exposure.

    "Chuck’s knowledge and understanding of breath alcohol instruments is exceptional.
