Nashville DUI Lawyer

"Nashville Criminal Defense Lawyer & Former Prosecutor Kevin Kennedy 615-205-7311. Call or text for a free consultation."

A DUI arrest in Nashville can affect far more than one court date. Tennessee DUI law can involve mandatory jail, fines, driver's-license revocation, ignition interlock requirements, alcohol or drug treatment, probation, enhanced punishment for prior convictions, and additional charges when an accident causes injury or death. A DUI can also affect employment, professional licensing, insurance, a commercial driver's license, and immigration consequences for some noncitizens.

The State still has to prove the case. A traffic stop must be lawful. The prosecution must establish driving or physical control and impairment or the applicable alcohol-concentration theory. Field sobriety testing, body-camera footage, breath or blood evidence, warrants, implied-consent procedures, laboratory analysis, prescription medications, and the timeline of alcohol consumption can all become important.

Nashville criminal defense lawyer Kevin Kennedy is a former prosecutor who has handled thousands of criminal cases. He analyzes DUI cases from the initial driving allegation through the stop, roadside investigation, arrest decision, chemical testing, laboratory evidence, and sentencing consequences.

This page replaces the broader "drunk driving" framing with the search-focused title Nashville DUI Lawyer while still covering alcohol DUI, drug DUI, refusal, accidents, repeat offenses, underage cases, CDL issues, and related Tennessee DUI charges.

What Is DUI in Tennessee?

Tennessee Code Annotated § 55-10-401 prohibits driving or being in physical control of a motor-driven vehicle on a public road, highway, alley, public parking lot, trailer park, or qualifying apartment-complex area while under the influence of an intoxicant, marijuana, controlled substance, drug affecting the central nervous system, or a combination that impairs the ability to safely operate the vehicle.

Tennessee also prohibits driving or being in physical control with an alcohol concentration of .08 percent or more under the applicable statutory testing framework. The State may therefore pursue an impairment theory, an alcohol-concentration theory, or both depending on the evidence.

A DUI case should be analyzed under the exact theory charged rather than assuming that an arrest or a BAC number automatically proves guilt.

Driving vs. Physical Control

A person does not necessarily have to be observed driving at the moment police arrive. Tennessee DUI law also reaches being in physical control of a vehicle in the locations covered by the statute.

Physical-control cases can involve a parked vehicle, a sleeping driver, a running engine, possession of keys, location of the vehicle, and evidence concerning whether the person recently drove or could readily operate the vehicle.

The defense should reconstruct where the vehicle was, where the person was located, where the keys were, whether the engine was running, and what independent evidence exists of actual driving.

The .08 BAC Rule

For most adult drivers, .08 percent is the familiar alcohol-concentration threshold in Tennessee DUI law. A chemical-test result can be powerful evidence, but it is not immune from challenge.

The defense should examine when the driving allegedly occurred, when the sample was obtained, testing method, instrument or laboratory records, chain of custody, observation requirements, and whether the result reliably reflects the relevant time.

A number should be treated as scientific evidence that must be validated, not as a substitute for analysis.

DUI Without a .08 BAC

A person can be prosecuted for DUI even without a .08 alcohol result if the State claims the person was under the influence to the extent that the ability to safely operate a motor vehicle was impaired.

Officer observations, driving, speech, balance, odor, admissions, field sobriety tests, video, drug evidence, and chemical testing can be used to support or challenge that theory.

Conversely, unusual behavior may have innocent explanations such as fatigue, anxiety, injury, medical conditions, road conditions, or poor footwear.

Alcohol DUI

Alcohol DUI cases commonly involve allegations of odor, bloodshot or watery eyes, slurred speech, admissions about drinking, poor driving, field sobriety tests, breath testing, or blood testing.

The defense should compare the officer's report with body-camera and dash-camera footage. Video may confirm impairment, but it can also show normal speech, steady movement, appropriate responses, and better driving than the report suggests.

Drug DUI

Tennessee DUI law is not limited to alcohol. Prescription medication, illegal drugs, marijuana, or combinations of substances can support a DUI theory if the statutory impairment requirements are proven.

Drug DUI cases often rely heavily on officer observations and blood testing. The presence of a substance or metabolite does not always answer whether the driver was impaired at the relevant time.

Pharmacology, dosage, prescription history, tolerance, timing, and laboratory interpretation can matter.

Prescription Drug DUI

A valid prescription does not automatically prevent a DUI charge. A lawfully prescribed medication can still impair driving.

But prescription evidence can provide important context concerning therapeutic use, dosage, timing, and why a substance was present in a blood sample.

The defense should obtain pharmacy and medical records when they are relevant and useful.

Marijuana DUI

Tennessee can prosecute driving under the influence of marijuana. Unlike alcohol's familiar .08 threshold, marijuana impairment cannot simply be reduced to an equivalent universal THC number.

Blood results, timing, driving behavior, field observations, admissions, and expert interpretation can all matter. THC and metabolite evidence should be evaluated carefully rather than treated as automatically proving impairment.

DUI and Fentanyl, Opioids, or Other Controlled Substances

Opioids and other controlled substances can produce a drug-DUI investigation when police believe they impaired safe operation.

Blood testing may identify multiple substances, including prescribed medications. The defense should determine the concentration, active versus inactive metabolites, timing, medical use, and whether the observed behavior is consistent with the State's impairment theory.

Traffic Stops in DUI Cases

Many DUI cases begin with speeding, lane movement, an equipment issue, a crash, a welfare check, or a citizen report.

The officer must have a lawful basis for the stop or detention. The defense should examine the precise driving allegation, video, road markings, weather, dispatch information, and what the officer knew before activating emergency equipment.

If the initial seizure was unconstitutional, evidence obtained afterward may be subject to suppression.

Lane Allegations

Reports may describe weaving, crossing lane lines, touching a fog line, wide turns, or inconsistent speed.

Dash-camera footage can be crucial. The defense should compare the actual driving to the traffic law cited and determine whether the officer had reasonable suspicion or probable cause for the stop.

Anonymous and Citizen Reports

Police sometimes locate a vehicle after a 911 caller reports erratic driving. The legality of the stop can depend on the content and reliability of the report, corroboration, and what officers observe themselves.

The 911 recording and dispatch records should be obtained rather than relying on a summary.

DUI Checkpoints

Tennessee DUI investigations can arise from sobriety checkpoints. Constitutional rules govern how checkpoints are established and operated.

The defense should obtain checkpoint plans, supervisory records, selection procedures, location information, and video where a checkpoint's legality is disputed.

Welfare Checks and Parked Vehicles

An officer may approach a parked or stopped vehicle to check on a driver. A consensual encounter can become a detention as the interaction develops.

The defense should identify the exact point at which the person was no longer free to leave and whether lawful justification existed at that moment.

Field Sobriety Tests

Standardized field sobriety tests commonly include horizontal gaze nystagmus, walk-and-turn, and one-leg stand. Officers may also use nonstandard exercises.

Performance can be affected by instructions, surface conditions, footwear, age, injuries, balance conditions, anxiety, fatigue, weather, lighting, and officer administration.

Body camera should be reviewed from the beginning of instructions through completion rather than relying solely on the officer's scoring.

Horizontal Gaze Nystagmus

HGN testing involves observations of the eyes while a stimulus is moved through specified positions. Proper administration and interpretation matter.

Medical conditions, test conditions, officer training, and documentation can become issues. The defense should compare the officer's testimony with the actual recorded administration where video exists.

Walk-and-Turn

The walk-and-turn is a divided-attention test with specific instructions. Officers look for standardized clues.

An imperfect test is not automatically proof of intoxication. The defense should examine whether instructions were correct, whether the surface was suitable, and whether the video actually supports the claimed clues.

One-Leg Stand

The one-leg stand asks a person to balance while counting according to instructions. Balance problems, age, injury, footwear, surface, wind, and anxiety can affect performance.

Video often provides the best evidence of what actually happened.

Nonstandard Roadside Tests

Officers sometimes ask a driver to recite the alphabet, count backward, touch a finger to the nose, or perform other exercises.

These tests should not be confused with the standardized NHTSA battery. Their administration and claimed significance should be examined separately.

Body-Camera Evidence

Body camera can show speech, coordination, demeanor, instructions, roadside conditions, statements, search activity, arrest procedures, and implied-consent discussions.

It can be among the most important evidence in a DUI case because it allows the court and defense to compare the officer's written conclusions with the recorded encounter.

Dash-Camera Evidence

Dash camera can show the actual driving before the stop and sometimes the roadside investigation.

Claims of weaving, near collisions, poor turns, or delayed stops should be compared with the footage.

Statements About Drinking

An admission to having one or more drinks is evidence, but it does not automatically prove DUI.

The timing, amount, type of alcohol, food consumption, body characteristics, and elapsed time can matter. The complete statement should be reviewed for context.

Miranda in DUI Cases

Not every roadside question requires Miranda warnings. Miranda generally applies to custodial interrogation.

The defense should determine when the encounter became custodial, what questions were asked, whether warnings were given, and whether the person invoked the right to remain silent or requested counsel.

Breath Testing

Breath-alcohol evidence depends on proper instrument operation, procedures, calibration and maintenance records, operator requirements, observation procedures, and the circumstances of the test.

The defense should obtain the relevant testing records and compare them with video and timestamps.

Mouth alcohol, timing, instrument issues, and procedural deviations can become relevant depending on the facts.

Blood Testing

Blood testing can measure alcohol and identify drugs. The defense should examine the legal authority for the draw, collection procedure, tube handling, chain of custody, laboratory methodology, quality-control records, and final report.

A hospital blood test and a forensic law-enforcement test may arise under different circumstances and should not be assumed to be interchangeable.

Search Warrants for Blood

Police may seek a search warrant for a blood sample when a driver refuses or in other circumstances.

The warrant affidavit should be reviewed for probable cause, material omissions or misstatements, timing, and compliance with the warrant's scope.

Implied Consent

Tennessee's implied-consent law governs requests for chemical testing in specified DUI-related investigations. A refusal can create driver's-license consequences even though an implied-consent violation is not itself treated as a criminal offense under current § 55-10-407.

The exact test requested matters. Current Tennessee law contains different consequences depending on prior history, serious-injury or fatal collisions, and---beginning in 2026---specified first-offense blood-test refusals.

Implied consent should be analyzed separately from whether the State can prove DUI.

Refusing a Breath or Blood Test

A refusal does not automatically prevent a DUI prosecution. The State may rely on observations and other evidence, and police may seek a warrant where legally permitted.

Current Tennessee law can impose substantial license consequences for refusal. As of 2026, certain first-time misdemeanor-DUI blood-test refusals carry a one-year-and-six-month license suspension, while other first refusals may carry one year under the current statutory structure.

Legislation enacted in 2026 changes part of this rule effective January 1, 2027, so the offense and refusal date matter.

Oral Fluid Testing

Tennessee law now permits oral-fluid testing in specified DUI-related circumstances, including consent, a search warrant, incident to a lawful arrest for covered offenses, or exigent circumstances as provided by statute.

Oral-fluid evidence is a developing area. Collection, laboratory procedures, substance detection, timing, and what the result proves about impairment should be carefully evaluated.

Rising Blood Alcohol

Alcohol concentration changes over time as alcohol is absorbed and eliminated. A test obtained after driving may not always equal the concentration at the time of driving.

Drinking timeline, food, test delay, and expert analysis may be relevant in an appropriate case.

Retrograde Extrapolation

Experts sometimes attempt to estimate an earlier alcohol concentration from a later test. Such analysis depends on assumptions concerning absorption, elimination, drinking pattern, and individual physiology.

The defense should identify the assumptions and determine whether the available facts support them.

Medical Conditions That Can Resemble Impairment

Diabetes, neurological conditions, injuries, fatigue, anxiety, speech differences, eye conditions, and other medical issues can sometimes affect observations officers associate with intoxication.

Medical evidence should be used carefully and only when genuinely supported.

Accidents and DUI

A crash can trigger a DUI investigation even when officers did not observe the driving beforehand.

The State may rely on witness testimony, admissions, vehicle evidence, event data, surveillance, phone records, and chemical tests to establish who drove and whether the person was impaired.

An accident alone does not prove DUI.

Single-Vehicle Accidents

Single-vehicle crashes can produce strong police suspicion, but road conditions, mechanical failure, animals, distraction, fatigue, weather, or other causes may explain the collision.

Crash reconstruction and vehicle data can matter in serious cases.

DUI With Injury

When intoxicated driving causes serious bodily injury, the investigation can move beyond misdemeanor DUI into vehicular assault or other felony charges depending on the facts.

Medical records, causation, intoxication evidence, crash reconstruction, and the statutory definition of serious bodily injury become critical.

Vehicular Assault

Tennessee vehicular assault generally addresses recklessly causing serious bodily injury to another as the proximate result of intoxication while operating a motor vehicle or qualifying vessel.

Recent Tennessee legislation has addressed the definition of serious bodily injury in this area, so current law and the offense date should be checked carefully.

Vehicular assault is a felony and should be defended as a serious injury case, not simply an enhanced DUI.

Vehicular Homicide

An intoxication-related fatal crash can lead to vehicular homicide. The State must prove intoxication, operation, proximate causation, and the other statutory elements.

These cases require immediate preservation of crash evidence, toxicology, vehicle data, phone evidence, surveillance, medical records, and witness accounts.

Aggravated Vehicular Homicide

Aggravated vehicular homicide can apply under specified circumstances involving prior DUI-related history or other statutory aggravating factors.

Tennessee has amended related intoxication thresholds and sentencing rules in recent years. The exact offense date and current statute should be reviewed rather than relying on older online summaries.

Leaving the Scene and DUI

A crash may produce separate leaving-the-scene or failure-to-render-aid allegations.

Leaving the scene can also affect how prosecutors view consciousness of guilt and, under 2026 Tennessee legislation, can have significant sentencing consequences when combined with intoxication-based vehicular homicide.

The defense should determine why the person left, what the person knew about the collision, and what actions were taken afterward.

First-Offense DUI

A first DUI conviction in Tennessee carries mandatory consequences, including minimum jail and fine requirements, license consequences, and other statutory conditions.

Tennessee's Department of Safety states that first offenders are subject to a minimum $350 fine and forty-eight hours in jail. Additional consequences can include treatment requirements and ignition interlock restrictions.

First-offense does not mean insignificant, and avoiding or reducing the conviction can have major long-term value.

High BAC and First DUI

Certain higher alcohol concentrations can increase mandatory minimum confinement under Tennessee DUI law.

The actual test, timing, admissibility, and offense-date statute should be verified before assuming an enhanced minimum applies.

Second DUI

A second DUI carries increased mandatory jail, fines, license revocation, and ignition-interlock consequences.

Prior convictions must qualify under Tennessee enhancement law. The defense should verify the prior judgment, offense date, conviction date, jurisdiction, and whether the prior offense is legally usable.

Third DUI

A third DUI carries substantially greater mandatory punishment and a longer driver's-license revocation.

Current Tennessee Department of Safety materials identify a six-year revocation for DUI third.

Prior-record analysis and challenges to the current DUI proof are especially important because enhancement consequences increase sharply.

Fourth or Subsequent DUI

A fourth or subsequent DUI is a felony under Tennessee law. It can involve significant incarceration, long-term license consequences, treatment, and other conditions.

The State must prove the qualifying prior convictions in addition to the current offense.

Ten-Year Lookback and Prior DUI Convictions

Tennessee uses statutory rules to determine which prior DUI-related convictions count for enhancement. The analysis can involve offense and conviction dates and prior offenses from other jurisdictions.

Do not rely on a background-check label alone. Certified judgments and the governing statute should be reviewed.

Out-of-State DUI Convictions

An out-of-state impaired-driving conviction may potentially affect Tennessee enhancement depending on whether it qualifies under Tennessee law.

The elements of the foreign offense and the judgment should be examined rather than assuming every out-of-state case counts.

Underage DUI

Drivers under twenty-one face special alcohol-related driving laws in addition to ordinary DUI. The applicable alcohol threshold and penalties differ from adult DUI.

A young driver may also face license, education, employment, and school consequences.

The exact charge should be identified because underage alcohol-driving offenses and standard DUI are not interchangeable.

DUI With a Child Passenger

Tennessee law provides enhanced consequences when a child is in the vehicle during a DUI, with particularly serious consequences if the child is injured or killed.

Passenger age, causation, and the underlying DUI evidence should be carefully reviewed.

Commercial Driver's License and DUI

A DUI can create separate CDL disqualification consequences even when the person was driving a personal vehicle.

Commercial drivers should address licensing consequences immediately because livelihood may depend on CDL status.

Federal and state commercial-driving rules can operate in addition to the criminal case.

DUI While Driving a Commercial Vehicle

Commercial-vehicle alcohol rules can be stricter than the ordinary .08 standard applicable to most adult drivers.

The defense should identify the vehicle classification, driver's license status, employer records, and exact charge.

Driver's License Revocation

A DUI conviction triggers driver's-license consequences. Tennessee's Department of Safety currently lists revocation periods of one year for DUI first, two years for DUI second, six years for DUI third, and eight years for DUI fourth or subsequent.

Eligibility for a restricted license and ignition interlock depends on the applicable statutes and individual circumstances.

License strategy should begin early rather than after conviction.

Restricted Driver's Licenses

Many DUI defendants need to drive for work, treatment, court, school, or family responsibilities. Tennessee law provides restricted-license mechanisms in qualifying circumstances.

Modern DUI restricted licenses often involve ignition interlock requirements. Eligibility should be determined from the exact conviction, revocation, and statutory restrictions.

Ignition Interlock

An ignition interlock requires a breath sample before a vehicle will start and may require rolling retests.

Tennessee's Department of Safety states that for DUI offenses occurring on or after January 1, 2023, compliance-based removal rules apply under § 55-10-425. The device must be properly installed and maintained for the required usage or revocation period.

Missed service, tampering, circumvention, or failed compliance can extend the process.

SCRAM and Alcohol Monitoring

Courts may use transdermal alcohol monitoring or other alcohol-monitoring devices as a bond or supervision condition depending on the case.

Tennessee legislation effective July 1, 2026 requires non-indigent defendants ordered to wear specified monitoring devices as a condition of pretrial release to pay associated fees.

Monitoring conditions should be followed exactly while the case is pending.

DUI Bond Conditions

Bond conditions can include no alcohol, drug testing, ignition interlock, transdermal monitoring, GPS, treatment, or other restrictions depending on the facts and court.

A new violation can jeopardize release and affect negotiations.

Counsel should make sure the client understands the written order rather than relying on memory from the bond hearing.

Alcohol and Drug Assessment

Tennessee DUI sentencing can require alcohol and drug assessment and treatment-related conditions.

Voluntary treatment before court may sometimes help with mitigation, but it should be coordinated with the defense and based on actual needs.

Probation

DUI sentences often include probation after mandatory confinement. Conditions can include reporting, treatment, testing, interlock compliance, and payment obligations.

A probation violation can lead to additional court proceedings and possible incarceration.

DUI and Employment

A DUI can affect jobs involving driving, company vehicles, security clearance, professional licensing, or employer background checks.

Commercial drivers, healthcare workers, pilots, government employees, and licensed professionals may have additional reporting or employment issues.

Defense strategy should consider collateral consequences before a plea.

DUI and Immigration

Immigration consequences depend on the exact offense, facts, and immigration status. DUI alone and DUI accompanied by drugs, injury, child endangerment, or other charges may raise different issues.

A noncitizen should obtain individualized immigration advice before resolving the case.

Can a DUI Be Expunged?

Tennessee DUI convictions generally have significant restrictions that distinguish them from many expungeable offenses. The exact current expungement law and disposition should be checked before advising that a record can be cleared.

A dismissal or other non-conviction disposition can present different record-clearing possibilities.

A defendant should understand the permanent-record implications before entering a plea.

Judicial Diversion and DUI

Standard DUI convictions are generally not treated like ordinary offenses eligible for judicial diversion. The exact charge and any negotiated alternative offense matter.

Counsel should not promise diversion merely because the person has no prior record.

Reducing a DUI Charge

A DUI may sometimes be reduced to another offense when the evidence, legal issues, prosecutor, and circumstances support it. No reduction is automatic.

Potential weaknesses can include an unlawful stop, poor field-test administration, favorable video, unreliable chemical evidence, rising BAC, insufficient proof of driving or physical control, or medical explanations.

The defense should develop those issues before negotiating.

DUI and Reckless Driving

Reckless driving is a separate offense and can arise as an alternative or companion charge depending on the driving evidence.

A negotiated reduction from DUI to another driving offense depends on the facts and prosecutorial discretion and should never be assumed.

Collateral consequences can differ substantially.

Suppression of DUI Evidence

Evidence can be suppressed when obtained through unconstitutional stops, seizures, searches, or interrogations.

A successful suppression motion can exclude driving observations, statements, chemical evidence, or other proof depending on the violation and causal connection.

The defense should identify constitutional issues before focusing solely on sentencing.

Challenging Chemical Test Evidence

Chemical-test challenges can involve legal authorization, collection, chain of custody, laboratory procedures, instrument records, quality control, timing, contamination, interpretation, and expert testimony.

The strongest challenge depends on the actual test and records. Generic attacks are less useful than case-specific scientific analysis.

Independent Testing

In some circumstances, defendants may have rights or practical opportunities concerning independent testing of samples or evidence.

Counsel should act promptly because biological samples and laboratory materials may have retention limits.

Discovery in a DUI Case

A thorough DUI defense should obtain more than the arrest report. Video, dispatch, testing records, warrants, laboratory materials, photographs, crash records, and officer training or certification information may matter.

The evidence should be organized into a timeline beginning before the stop and ending after testing.

Preparing a DUI Case for Trial

A DUI trial should tell a coherent story about the driving, stop, roadside observations, field tests, arrest decision, chemical evidence, and alternative explanations.

The defense should decide whether the central issue is legality of the stop, impairment, test reliability, physical control, drug interpretation, or another element.

Video and scientific evidence should be used precisely rather than overloaded with technical detail that does not affect the disputed issue.

Important Evidence to Obtain in a Nashville DUI Case

  • Body-camera and dash-camera footage.
  • 911 calls, dispatch records, and traffic-stop timestamps.
  • Photographs and diagrams of the road, crash scene, or field-test location.
  • Field sobriety testing video and officer reports.
  • Breath-test printouts, instrument records, maintenance and calibration materials.
  • Blood-draw records, chain-of-custody documents, laboratory reports, and quality-control materials.
  • Search warrants and supporting affidavits.
  • Implied-consent forms and recordings of the advisement.
  • Hospital records where medical testing or treatment is relevant.
  • Prescription and pharmacy records in drug-DUI cases.
  • Crash reports, vehicle event data, and reconstruction evidence.
  • Surveillance or third-party video showing driving or alcohol consumption.
  • Receipts and witnesses relevant to the drinking timeline.
  • Phone or location records where identity of the driver or timing is disputed.
  • Certified judgments for any prior DUI convictions alleged for enhancement.

Common DUI Defenses and Challenges

  • The traffic stop or detention was unlawful.
  • The State cannot prove the defendant was driving or in physical control.
  • Body-camera footage does not support the officer's impairment description.
  • Field sobriety tests were improperly administered or affected by physical or environmental conditions.
  • Breath testing was unreliable or procedures were not followed.
  • The blood draw or blood search violated constitutional requirements.
  • Laboratory, chain-of-custody, or interpretation problems undermine the chemical result.
  • Alcohol concentration rose after the driving but before the test.
  • Prescription medication was present but did not impair safe driving.
  • Drug presence does not prove impairment at the time of driving.
  • Medical conditions or injuries explain alleged impairment clues.
  • The State cannot prove causation in an accident-based felony case.
  • A prior conviction does not legally qualify for enhancement.
  • Statements were obtained in violation of constitutional protections.

Why Hire a Former Prosecutor for a Nashville DUI Case?

DUI cases are evidence-intensive. The officer's report may make the case sound straightforward, but the video, timestamps, chemical-test records, and actual driving can tell a different story.

Kevin Kennedy previously handled thousands of criminal cases as a prosecutor. As a Nashville defense lawyer, he uses that experience to identify what prosecutors will rely on, which weaknesses matter in negotiations or trial, and whether constitutional or scientific issues undermine the State's proof.

The goal is to evaluate the case from the first claimed traffic violation through the final laboratory result rather than treating a DUI arrest as a conviction.

What to Do After a Nashville DUI Arrest

  • Do not miss court.
  • Follow every bond condition involving alcohol, drugs, driving, interlock, or monitoring.
  • Do not drive while your license is revoked or outside the terms of a restricted license.
  • Preserve receipts, messages, photographs, and witnesses relevant to the drinking or medication timeline.
  • Write down where you were, what you consumed, and when while your memory is fresh.
  • Tell counsel about medical conditions, injuries, prescriptions, and dental issues that may affect testing.
  • Do not delete phone or location evidence.
  • Provide counsel with paperwork concerning breath, blood, refusal, towing, and license consequences.
  • Have the defense obtain body-camera and dash-camera footage promptly.
  • Verify any prior DUI convictions the State claims enhance the case.
