A DUI arrest in Wilson County can unravel your week before you fully understand what happened. One traffic stop leads to field tests, a chemical test, handcuffs, and a ride to booking. By the next morning you face criminal charges, a possible license suspension, and questions about your job and your future. Turnbow Law represents clients in Lebanon, Mt. Juliet, and throughout Middle Tennessee who need someone to slow the process down and explain what comes next.
What Counts as a DUI Under Tennessee Law
Tennessee makes it illegal to operate or be in physical control of a motor vehicle while impaired by alcohol, drugs, or both. That language matters. You do not have to be driving erratically or cause an accident. Officers can base an arrest on what they observe during a traffic stop, the results of field sobriety tests, and chemical testing.
The state measures alcohol impairment through blood alcohol concentration. For most drivers over 21, a BAC at or above the legal threshold creates a presumption of impairment. Tennessee holds commercial drivers to a stricter standard, and drivers under 21 face a zero-tolerance policy where any measurable amount of alcohol can result in charges.
Drugs play a role too. Prescription medications, over-the-counter drugs, and illegal substances can all support a DUI charge if they affect your ability to drive.
You Do Not Have to Be Driving
This catches people off guard. Tennessee law covers “physical control” of a vehicle, not just active driving. Courts have upheld DUI charges against people who were parked, asleep behind the wheel, or sitting in a running car with no intention of going anywhere. If you had the ability to put the vehicle in motion while impaired, prosecutors may argue that is enough. Your attorney can challenge how “physical control” applies to your specific facts, but you should know the law reaches further than most people expect.
How Turnbow Law Examines the Evidence Against You
DUI cases depend heavily on technical evidence, and each piece of that evidence has requirements attached to it. When any of those requirements are not met, the evidence can be challenged or excluded.
The traffic stop itself has to be lawful. Officers need reasonable suspicion to pull you over. If the stop lacks legal justification, everything that follows may be subject to suppression. Field sobriety tests have their own problems. They must follow standardized procedures, and factors like weather, lighting, road surface, footwear, and medical conditions can all affect the results. An officer who skips steps or gives unclear instructions weakens the reliability of those tests.
Breath and blood testing carry strict calibration and chain-of-custody requirements. A breath testing device that was not properly maintained or a blood draw that did not follow protocol can produce results that your attorney can challenge in court. Officer observations about your speech, coordination, and appearance are subjective and may conflict with what body camera footage actually shows.
Two Separate Processes Run at the Same Time
Something that surprises many people after a DUI arrest is that the criminal case and the administrative license action operate on separate tracks. Resolving one does not automatically resolve the other, and each has its own deadlines.
On the administrative side, your driving privileges may face suspension regardless of what happens in criminal court. Tennessee’s implied consent law means that refusing a chemical test triggers its own penalties, including automatic license suspension. Missing deadlines on the administrative side can cost you options that were available right after the arrest. This is one of the reasons early legal involvement matters so much.
Penalties Stack Up Quickly
Tennessee treats repeat DUI offenses with increasing severity, but even a first offense carries real consequences. Penalties can include jail time, fines, mandatory alcohol or drug education programs, probation, license suspension, and ignition interlock requirements on your vehicle.
Aggravating factors push penalties higher. A BAC well above the legal limit, an accident, injuries, or having a minor passenger in the vehicle can all lead to enhanced sentencing. Beyond the criminal penalties, a conviction affects your insurance costs, shows up on background checks, and can create problems with professional licensing and employment.
What a Defense Strategy Actually Looks Like
There is no single playbook for DUI defense. Turnbow Law evaluates each case on its own facts and builds a strategy around the specific weaknesses in the prosecution’s evidence.
In some cases, the focus is on suppression. If the traffic stop was unlawful or the chemical test was flawed, the case may not survive a challenge to the evidence. In other cases, negotiation toward reduced charges or alternative sentencing makes more practical sense given the circumstances. Your attorney assesses the strength of the evidence, your prior history, and what outcomes are realistic before recommending a path forward.
Act Before Your Options Narrow
A DUI charge puts multiple things at risk at the same time: your license, your record, your job, and your freedom. The administrative deadlines alone make it important to talk to an attorney quickly. Turnbow Law represents clients across Wilson County and Middle Tennessee who need experienced DUI defense from someone who knows how local courts handle these cases. Reach out early, understand your options, and start building a defense before the process moves forward without you.
