Garza Law Firm – Navigating Tennessee DUI Laws

Driving Under the Influence (DUI) charges in Tennessee are far more complicated than many realize. These cases sit at the crossroads of criminal law, constitutional rights, and scientific evidence, a combination that creates significant challenges for the accused. Given the potential consequences, including jail time, loss of license, heavy fines, and a permanent criminal record, the stakes couldn’t be higher.

Garza Law offers a powerful combination of in-house expertise and deep regional connections, setting it apart from other firms. The firm employs a team of full-time investigators, including former law enforcement professionals (all of whom are on staff) ensuring consistency, reliability, and a deep understanding of criminal procedures.

The criminal team is run by firm founder, Marcos Garza. The firm prioritizes continued education, sending all 10 of its experienced criminal defense attorneys to specialized and advanced DUI trainings and conferences regularly. With daily work across eastern Tennessee, this team is highly familiar with the courts, judges, and prosecutors in each county. They are not only well-versed in litigation but also have extensive knowledge of constitutional and legal issues specific to DUI cases. Garza Law provides clients with aggressive, informed, and empathetic defense throughout every stage of the case.

DUI Landscape in Tennessee

Tennessee categorizes first, second, and third DUIs as misdemeanors, while fourth and subsequent offenses can be charged as felonies. Repeat offenders face a slightly different setup.

DUIs have a “lookback” period in Tennessee that significantly impacts sentencing for repeat offenders. If a person is charged with a DUI and has a prior DUI conviction within the past 10 years, the new charge will be treated as a second offense, bringing enhanced penalties such as longer mandatory jail time, increased fines, and extended license suspension. In addition, the lookback period can effectively extend to 20 years: if someone was convicted of a DUI that occurred within the last 10 years, the lookback period then extends to another 10 years, not to exceed 20 years. In sum, your past criminal history can enhance the penalties for your current DUI.

With that in mind, here’s a breakdown of what you may face in Tennessee for first, second, and subsequent DUI offenses.

Fourth & Subsequent DUI Offenses — Felony Land

Facing a DUI charge in Tennessee can feel overwhelming. The laws are strict, the penalties severe, and the consequences life-changing. But you don’t have to face this alone.
