Driving under the influence prosecutions in Davidson County run on a statutory track that diverges sharply from general criminal defense. Tennessee Code Annotated 55-10-401 sets the per se threshold at .08 blood-alcohol concentration for adult drivers, .04 for commercial drivers, and .02 for drivers under 21 under the underage driving provision. Mandatory minimum jail sentences escalate by offense level under Tennessee Code Annotated 55-10-402, with a forty-eight-hour floor on a first conviction, forty-five days on a second, one hundred twenty days on a third, and a Class E felony designation that attaches on a fourth offense. The Tennessee Implied Consent Law under Tennessee Code Annotated 55-10-406 imposes a separate civil license revocation track that runs in parallel with the criminal prosecution.
Evidentiary defense in a Tennessee DUI case turns on the Intoxilyzer EC/IR II breath testing instrument used by Metro Nashville Police Department, the National Highway Traffic Safety Administration Standardized Field Sobriety Test battery of horizontal gaze nystagmus, walk-and-turn, and one-leg stand, and the ignition interlock requirement under Tennessee Code Annotated 55-10-417. The three Nashville firms profiled below each carry DUI-specific credentials beyond a general criminal defense docket, with documented National College for DUI Defense membership, DUI Defense Lawyers Association affiliation, or career emphasis on driving-under-the-influence charges measured in thousands of cases handled.

2. Law Office of Bernie McEvoy #
Law Office of Bernie McEvoy sits at 214 Second Avenue North, Suite 206, Nashville, TN 37201, reachable at (615) 255-9595. Bernie McEvoy earned a Juris Doctor from Vanderbilt University Law School in 1990 after a Bachelor of Arts from Tufts University, and entered the Davidson County District Attorney General’s Office that year, serving as a state prosecutor for fifteen years before opening the current defense practice.
Former head of the Davidson County DUI prosecution team #
McEvoy headed the DUI and vehicular homicide prosecution team within the Davidson County District Attorney General’s Office, trying more than one hundred DUI cases and ten vehicular homicide cases as a prosecutor before crossing to the defense bar. The fifteen-year prosecution tenure included six years on child abuse and homicide prosecutions, providing a procedural and evidentiary lens that informs current pretrial motion practice on suppression of breath test results, blood draw consent challenges under Missouri v. McNeely, 569 U.S. 141 (2013) and State v. Reynolds, and Standardized Field Sobriety Test administration deviation.
DUI sub-area practice mapped to Tennessee statute #
Practice scope covers first-time DUI, repeat DUI through the Class E felony threshold at fourth offense, underage DUI under Tennessee Code Annotated 55-10-415, aggravated vehicular homicide under Tennessee Code Annotated 39-13-218, drugged driving prosecutions involving Schedule I through V controlled substances, commercial driver DUI carrying the .04 per se threshold, DUI checkpoint stops governed by the Brown v. Texas balancing test, implied consent refusal under Tennessee Code Annotated 55-10-406, restricted license petitions, ignition interlock proceedings under Tennessee Code Annotated 55-10-417, breath test and blood test challenges, and DUI with a minor in the vehicle under Tennessee Code Annotated 55-10-402(c).
Continuing-legal-education instruction in DUI defense #
McEvoy lectures on DUI defense and child abuse defense within the continuing-legal-education circuit. CLE faculty status requires sustained subject-matter currency, and instruction on driving-under-the-influence litigation ties into review of the Tennessee Bureau of Investigation toxicology laboratory protocols, the Intoxilyzer EC/IR II twenty-minute observation period requirement, and chain-of-custody documentation for blood draws performed under search warrant.

3. Law Office of Bryan Stephenson #
Law Office of Bryan Stephenson operates from 2021 Richard Jones Road, Suite 150E, Nashville, TN 37215, reachable at (615) 515-5110.

DUI Defense Lawyers Association membership #
Stephenson holds membership in the DUI Defense Lawyers Association, a national professional organization focused on driving-under-the-influence trial advocacy and forensic science training. DUIDLA membership tracks against continuing-legal-education credit hours in DUI-specific subject matter and ties into the Mastering Scientific Evidence seminar curriculum that the organization co-sponsors with the National College for DUI Defense.
Former prosecutor crossover at the Davidson County DAG office #
Service as an Assistant District Attorney in Davidson County provides procedural familiarity with charging decisions at the General Sessions Court level, plea-bargain calibration ahead of preliminary hearing, and grand jury indictment posture on aggravated DUI matters routed to Criminal Court. Pretrial motion practice on Fourth Amendment search-and-seizure suppression under Tennessee Rules of Criminal Procedure 12 draws from the prosecutorial perspective on traffic stop initiation, reasonable suspicion development, and probable cause for arrest under Tennessee v. Garcia.
Practice scope across DUI and adjacent charges #
The office accepts first-time DUI, multiple-offense DUI through the Class E felony level, vehicular assault under Tennessee Code Annotated 39-13-106, vehicular homicide under Tennessee Code Annotated 39-13-213, drug possession and distribution charges under the Tennessee Drug Control Act, weapons offenses including unlawful carrying under Tennessee Code Annotated 39-17-1307, domestic assault under Tennessee Code Annotated 39-13-111, and probation violation proceedings. Implied consent license revocation hearings before the Tennessee Department of Safety and Homeland Security route through the administrative track parallel to the criminal docket.
Selection Methodology #
DUI defense in Tennessee tracks against TCA 55-10-401, the implied-consent rule at TCA 55-10-406, the felony-DUI threshold at fourth offense, and the field-sobriety and BAC evidentiary rules adopted in Davidson County General Sessions and Criminal Court. The filter for the three practices above started with how long the lead attorney has tried DUI cases to verdict in Davidson County, then worked through National College for DUI Defense membership, NHTSA Standardized Field Sobriety Test instructor or practitioner certification, Tennessee Association of Criminal Defense Lawyers membership, published verdict and dismissal history, and a Davidson County office address that matches the BPR register. Out-of-state DUI-marketing networks routing calls to unadmitted attorneys were excluded.
How to Choose Among These Three Nashville DUI Defense Offices #
Offense-level posture, evidentiary fact pattern, and procedural stage should drive the selection inquiry. A first-time DUI arrest with a borderline Intoxilyzer reading, a refusal posture triggering implied consent revocation, or a checkpoint stop with documented Standardized Field Sobriety Test administration questions calls for counsel with NCDD or DUIDLA credentialing, which the Law Offices of Thomas T. Overton and the Law Office of Bryan Stephenson both carry. A multiple-offense matter with prior-conviction enhancement exposure or a vehicular homicide indictment under Tennessee Code Annotated 39-13-213 fits the trial-tested dockets at all three offices, with the Law Office of Bernie McEvoy bringing direct prior service heading the Davidson County DUI and vehicular homicide prosecution team.
Verification of credentials can proceed through the Tennessee Board of Professional Responsibility license-status lookup, the National College for DUI Defense member directory at ncdd.com, the DUI Defense Lawyers Association member directory at duidla.org, and the Davidson County General Sessions Court and Criminal Court clerk records for case history. Tennessee Department of Safety and Homeland Security administrative license revocation status under Tennessee Code Annotated 55-10-406 runs on a fast clock, with the implied consent revocation hearing request window opening at the moment of arrest.
Initial consultations at DUI defense offices typically address conflict-check clearance under Tennessee Rule of Professional Conduct 1.7, retainer-agreement terms governed by Rule 1.5, scope-of-representation definition under Rule 1.2, and confidentiality obligations under Rule 1.6. Early counsel engagement matters in a Tennessee DUI case, with the implied consent civil license revocation timeline running independent of the criminal docket and the Intoxilyzer maintenance log production routing through formal discovery requests under Tennessee Rules of Criminal Procedure 16.
Frequently Asked Questions #
Q: Is the initial consultation free or paid?
A: Some Nashville firms offer a complimentary initial consultation for a defined practice area, others charge a flat or hourly intake fee that may or may not credit toward the engagement if the matter proceeds. Confirm the consultation fee structure in writing before booking, and ask whether the conversation is privileged regardless of whether the firm is retained.
Q: How does the firm structure fees: hourly, flat, or contingency?
A: Fee structure depends on the matter type. Litigation and complex matters are often hourly with a retainer trust deposit; transactional and certain defined-scope matters may be flat fee; plaintiff personal injury, workers compensation, and similar matters are commonly contingency with a stated percentage. Request the full fee structure and expense pass-through policy in writing before signing the engagement letter.
Q: Are any of the three firms paid placements?
A: No. The three profiles above are editorial selections drawn from publicly verifiable sources. No firm sponsored placement.
Q: What is the typical case or matter timeline for this practice area?
A: Timelines vary widely by court docket, opposing counsel responsiveness, discovery scope, and settlement posture. Ask the firm for a written timeline estimate broken into typical phases (intake, investigation, pleadings, discovery, resolution) and the lawyer’s communication expectations at each phase. Davidson County and federal Middle District calendars also affect timing.
