Being arrested for DUI in Nashville, TN can be confusing and frightening. For many people, it is their first encounter with the criminal courts. A traffic stop that lasts only a few minutes may lead to months of hearings and legal obligations. The best way to approach this situation is to understand the Tennessee DUI case timeline, how a case begins, what stages follow, and how long each step might take.
This article explains each stage, from the moment blue lights appear in the mirror to the trial itself. Knowing the order of events can help people facing charges prepare for what lies ahead and reduce the stress of uncertainty.
DUI Traffic Stop Process in Tennessee
Every DUI case starts with a traffic stop. Officers may pull a driver over after seeing a violation, observing signs of unsafe driving, or conducting a legally approved sobriety checkpoint. Tennessee allows checkpoints, but they must follow strict rules to be constitutional, including advance planning and neutral guidelines that limit officer discretion.
Once a vehicle is stopped, officers look for clues of impairment, such as the odor of alcohol, slurred speech, glassy eyes, or trouble providing documents. Drivers may also be asked to perform standardized field sobriety tests. Only three of these—the horizontal gaze nystagmus, the walk-and-turn, and the one-leg stand—are validated by the National Highway Traffic Safety Administration for detecting alcohol impairment (NHTSA Manual). Other tests may be used, but they do not carry the same scientific reliability.
If the officer concludes there is probable cause, the next step is arrest.
The DUI Arrest Process in Tennessee
An arrest is the formal start of a DUI case. Once probable cause is established, the driver is placed in custody, handcuffed, and taken to jail.
At this stage, officers often request a chemical test. Tennessee follows an implied consent law: anyone driving on public roads has already agreed to submit to a breath or blood test if lawfully arrested for DUI (Tenn. Code Ann. § 55-10-406). Refusing the test carries its own penalty—license suspension—even if the DUI charge is later dismissed.
The arrest sets the court process in motion and begins the deadlines that shape the case timeline.
Booking and Bail After a Tennessee DUI Arrest
Following an arrest in Nashville, TN, the driver is booked. Booking includes photographs, fingerprints, and recording of personal details.
Next, a magistrate considers bail. State law requires judges to use the least restrictive conditions that will reasonably assure the person will appear in court and protect the community (Tenn. Code Ann. § 40-11-116). Sometimes defendants are released on their own recognizance, which means no money is paid but they promise to return for hearings.
In certain DUI situations, release can include strict conditions. If the driver has a prior DUI conviction, a child passenger, or the crash involved serious injury, the court must require an ignition interlock device as part of pretrial release. The defendant must show proof of installation within ten days.
Once released, the case moves toward arraignment.
The DUI Arraignment Timeline in Tennessee
Tennessee law requires that an arrested person be brought before a magistrate without unnecessary delay (Tenn. R. Crim. P. 5). The arraignment, which is the formal hearing where a plea is entered, is scheduled once the case is placed on the court’s docket (Rule 10).
At this hearing, the judge reads the charges and the defendant chooses a plea—guilty, not guilty, or no contest. In most DUI cases, defendants enter a not guilty plea at this stage to preserve their right to review evidence and consider negotiation. Conditions of release may also be revisited, including mandatory interlock installation where the statute applies.
DUI Pre-Trial Hearings and Motions
The pre-trial phase is often the longest part of a DUI case in Nashville. Both sides exchange evidence, and the defense may request materials under Rule 16.
Defendants can also file motions to suppress evidence. For example, they may challenge whether the traffic stop was legal, whether field sobriety tests were administered correctly, or whether the blood or breath test was reliable. Tennessee requires that these motions be filed before trial (Tenn. R. Crim. P. 12(b)(2)(C)).
During this stage, the prosecution and defense often discuss possible plea agreements. Some cases end here if both sides reach a resolution. If not, the case proceeds to trial.
DUI Trial Timeline in Tennessee
If no plea agreement is reached, the case goes to trial. A defendant has the right to have a jury decide the case, though this right can be waived with the court’s and prosecution’s consent. If waived, a judge alone hears the evidence (Tenn. R. Crim. P. 23).
A trial includes jury selection, opening statements, witness testimony, cross-examination, and closing arguments. The prosecution must prove beyond a reasonable doubt that the defendant drove while impaired or with a blood alcohol concentration of 0.08 or higher (Tenn. Code Ann. § 55-10-401).
The length of trial varies. Some cases finish in a single day, while others stretch across several days depending on how much evidence is presented.
How Long Does a DUI Case Take in Tennessee?
The time from arrest to final outcome differs widely. Some cases in Nashville, TN end quickly if a plea is reached early. Others may take several months due to motion practice, crowded dockets, or the need for expert testimony.
If there is a conviction, Tennessee requires sentencing without unreasonable delay and no later than 45 days after the finding of guilt (Tenn. Code Ann. § 40-35-209).
