Turnbow Law represents individuals charged with driving under the influence (DUI) throughout Middle Tennessee. Attorney Chad Turnbow provides detailed, fact-driven defense for clients facing DUI allegations under Tennessee law.
A DUI charge is a serious criminal offense with consequences that extend well beyond the courtroom. Even a first offense can result in license suspension, substantial fines, mandatory education programs, increased insurance costs, and potential jail time. Repeat offenses carry significantly enhanced penalties. Because DUI cases often rely on technical evidence and procedural compliance, thorough legal review is essential.
DUI Laws in Tennessee
Under Tennessee law, a person may be charged with DUI if they are alleged to have operated or been in physical control of a motor vehicle while impaired by alcohol, drugs, or a combination of both. A blood alcohol concentration (BAC) of 0.08% or higher is considered per se impairment for most drivers, though lower thresholds apply for commercial drivers and individuals under 21.
Importantly, a DUI charge does not require proof of unsafe driving. Arrests may occur based on officer observations, chemical test results, or field sobriety testing. Each of these elements must comply with constitutional and statutory requirements.
Common DUI Evidence Examined in Defense
DUI cases are highly evidence-dependent. Turnbow Law carefully evaluates all aspects of the arrest and investigation, including:
Traffic Stop Legality
Law enforcement must have lawful justification to initiate a traffic stop. If a stop lacks reasonable suspicion or probable cause, evidence obtained afterward may be subject to suppression.
Field Sobriety Tests
Standardized field sobriety tests must be administered correctly and under appropriate conditions. Factors such as lighting, weather, medical conditions, and instructions given to the driver can affect reliability.
Breath and Blood Testing
Chemical testing devices must be properly maintained, calibrated, and administered. Blood draws must follow strict protocols. Errors or deviations can compromise test results.
Officer Observations
Reports regarding appearance, speech, coordination, and behavior are subjective and may be inconsistent with video evidence or other facts.
Penalties for DUI Convictions
DUI penalties in Tennessee escalate based on prior convictions and case circumstances. Possible consequences include:
- Jail time
- Monetary fines and court costs
- Driver’s license suspension or revocation
- Ignition interlock requirements
- Mandatory alcohol or drug education programs
- Probation supervision
Aggravating factors, such as high BAC levels, accidents, injuries, or minor passengers, may result in enhanced sentencing exposure.
Administrative and Criminal Proceedings
DUI cases often involve both criminal court proceedings and administrative driver’s license actions. These processes operate independently and on different timelines. Addressing one does not automatically resolve the other.
Understanding deadlines and procedural requirements is critical, particularly where license privileges and eligibility for restricted driving are concerned.
Defense Strategy Considerations
DUI defense is not a one-size-fits-all process. Turnbow Law evaluates each case individually, considering:
- The manner in which the stop occurred
- Evidence collection methods
- Prior criminal or driving history
- Available alternatives to conviction
In some cases, defense efforts focus on suppression of evidence. In others, negotiation or sentencing mitigation may be appropriate depending on the facts.
Long-Term Consequences of DUI Convictions
Beyond immediate penalties, a DUI conviction can have lasting effects on:
- Employment opportunities
- Professional licenses
- Auto insurance availability and cost
- Background checks
Because DUI convictions remain on criminal records, understanding both short- and long-term implications is essential when navigating a case.
