Is a DUI a Felony in Tennessee?
Under Tennessee state law (Tennessee Code Annotated § 55-10-401), the majority of first, second, and third driving under the influence (DUI) offenses are prosecuted as Class A misdemeanors. However, drivers frequently wonder under what circumstances a DUI escalates into a devastating, life-altering felony conviction. In Tennessee, a DUI transitions from a misdemeanor into a major felony based on two distinct legal catalysts: accumulated repeat offenses within a rolling 10-year lookback window (a 4th or subsequent DUI) or collisions resulting in serious bodily injury or death.
Tennessee DUI Classification: Misdemeanor vs Felony Thresholds
The statutory threshold where a repeat DUI becomes a felony in Tennessee occurs on the Fourth Offense DUI. Under TCA § 55-10-402, while first, second, and third DUIs are classified as Class A misdemeanors carrying mandatory minimum jail sentences of 48 hours, 45 days, and 120 days respectively, a Fourth Offense DUI is formally codified as a Class E Felony. Conviction of a fourth DUI triggers a mandatory minimum prison sentence of 365 consecutive days with zero eligibility for early probation, maximum fines up to $15,000, and permanent revocation of driving privileges.
Tennessee legislation establishes even harsher felony enhancements for Fifth and Sixth DUI offenses. A Fifth Offense DUI is classified as a Class D Felony carrying a mandatory minimum prison term of two continuous years (up to 12 years maximum). A Sixth or Subsequent DUI escalates to a severe Class C Felony mandating a minimum of three years of actual prison incarceration, substantial punitive fines, and vehicle forfeiture under state criminal seizure laws.
Review the detailed comparison and breakdown in the table below:
| DUI Offense Tier | Tennessee Statutory Charge | Legal Classification | Mandatory Minimum Jail Time | Maximum Incarceration |
|---|---|---|---|---|
| 1st Offense DUI | TCA § 55-10-401 | Class A Misdemeanor | 48 hours (7 days if BAC >= .20%) | 11 months, 29 days |
| 2nd Offense DUI | TCA § 55-10-402 | Class A Misdemeanor | 45 consecutive days in jail | 11 months, 29 days |
| 3rd Offense DUI | TCA § 55-10-402 | Class A Misdemeanor | 120 consecutive days in jail | 11 months, 29 days |
| 4th Offense DUI | TCA § 55-10-402 | Class E FELONY | 365 consecutive days in prison | Up to 6 years in prison |
| 5th Offense DUI | TCA § 55-10-402 | Class D FELONY | 2 full years in prison | Up to 12 years in prison |
| 6th+ Offense DUI | TCA § 55-10-402 | Class C FELONY | 3 full years in prison | Up to 15 years in prison |
When a DUI Becomes a Felony: 4th Offenses, Vehicular Assault, and Homicide
A DUI automatically bypasses misdemeanor status and becomes an immediate felony—even for a first-time offender with a pristine driving record—if an alcohol or drug-impaired collision causes bodily injury to another person. If an impaired driver causes serious bodily injury involving substantial risk of death, protracted disfigurement, or loss of bodily function, the charge is Vehicular Assault (TCA § 39-13-106). Vehicular Assault is an immediate Class D Felony punishable by 2 to 12 years in state prison, license revocation for up to 5 years, and mandatory restitution.
The most catastrophic felony DUI charge in Tennessee is Vehicular Homicide (TCA § 39-13-213). If an impaired driver causes the death of another person as a proximate result of intoxication, the offense is charged as a Class B Felony carrying a mandatory 8 to 30-year state prison sentence without eligibility for judicial diversion. If the defendant has prior DUI convictions or an extreme blood alcohol concentration (BAC of 0.20% or higher), the state can prosecute under Aggravated Vehicular Homicide—a Class A Felony carrying 15 to 60 years of incarceration and mandatory minimum 85% service before parole eligibility.
Examine the key benchmarks and metrics outlined in the table below:
| Aggravating Factor | Resulting Felony Charge | Felony Class | Mandatory State Prison Term |
|---|---|---|---|
| Serious Bodily Injury to Victim | Vehicular Assault (TCA 39-13-106) | Class D Felony | 2 to 12 years prison term |
| Fatal Crash (Intoxication) | Vehicular Homicide (TCA 39-13-213) | Class B Felony | 8 to 30 years state prison |
| Fatal Crash + Prior DUIs / BAC .20+ | Aggravated Vehicular Homicide | Class A Felony | 15 to 60 years (Must serve 85%) |
| DUI with Minor Child in Vehicle | Child Endangerment Enhancement | Class A Misd / Class D Felony | Mandatory 30 days jail min + felony if hurt |
Mandatory Penalties: Consecutive Prison Time, Fines, and Lifetime Revocation
The collateral consequences of a felony DUI conviction in Tennessee permanently alter a citizen's civil rights and future livelihoods. Under Tennessee law, convicted felons permanently lose their constitutional right to vote (disenfranchisement), lose their Second Amendment right to own or possess firearms, face automatic revocation of professional state licenses (nursing, legal, commercial contractors, real estate), and endure permanent criminal records that cannot be expunged under Tennessee expungement statutes.
Consult the specifications and reference data in the table below:
| Felony Collateral Consequence | Tennessee Statutory Impact | Restoration Pathway | Permanence |
|---|---|---|---|
| Loss of Voting Rights | Immediate disenfranchisement upon sentencing | Requires formal petition after sentence completed | Revoked until court restoration |
| Firearm Ownership Ban | Federal & state lifetime gun ownership ban | Extremely rare presidential/gubernatorial pardon | Permanent lifetime prohibition |
| Driver License Revocation | Mandatory multi-year or lifetime revocation | Hardship IID license after mandatory wait | Requires restricted IID interlock |
| Criminal Record Expungement | Felony DUIs NEVER eligible for expungement | Zero expungement available under TN law | Permanent public criminal record |
