Tennessee Alcohol Laws: Hours, DUI Limits, and Penalties

Tennessee alcohol laws set the drinking age at 21, route spirits through licensed package stores, allow wine in qualifying grocery stores, leave beer to local governments, and let each county or city vote itself dry. Drinking and driving carries fines from $350 up to $15,000 depending on prior convictions, and refusing a breath or blood test costs you your license for at least a year. The rules below cover what you can buy, where and when, and what happens when the law is broken.

Drinking Age and ID Checks

You must be 21 to buy, possess, transport, or consume any alcoholic beverage, wine, or beer in Tennessee.¹ Two narrow exceptions apply: an 18-year-old employee may handle alcohol as part of their job, and clergy may administer wine at religious ceremonies.

Retailers must check a valid, government-issued photo ID with a date of birth before completing an off-premises sale. The only safe harbor is for buyers who reasonably appear over 50. If a customer looks younger than 50 and doesn’t produce ID, the sale can’t happen. Retailers who follow the rule are shielded from criminal prosecution and license action even if the buyer turns out to be underage.²

An underage person who tries to buy alcohol commits a Class A misdemeanor. An adult who buys for someone under 21 faces a fine of $25 to $500 for a first offense, and $50 to $1,000 for later ones, plus exposure under the state’s contributing-to-the-delinquency-of-a-minor statute.³

Where and When You Can Buy Alcohol

Tennessee splits retail into three channels, each with its own product list and hours.

Liquor Stores

Licensed retail package stores sell spirits, wine, and high-alcohol-content beer. They may open Monday through Saturday from 8:00 a.m. to 11:00 p.m., and Sunday from 10:00 a.m. to 11:00 p.m. They must close entirely on Christmas, Thanksgiving, and Easter.⁴

Grocery Stores and Wine

Qualifying retail food stores may sell wine but not spirits. To qualify, a store needs at least 20% of its taxable sales from food and food ingredients and at least 1,200 square feet of retail floor space.⁵ That threshold rules out most convenience stores and gas stations. Wine sales follow the same daily hours as liquor stores, including the 10:00 a.m. Sunday start.

Beer

Beer at 8% alcohol by weight or less is regulated locally, not by the state ABC.⁶ Cities and counties issue beer permits through local beer boards with broad authority to set opening and closing hours, distance requirements from schools and churches, zoning restrictions, and caps on the total number of permits. Beer hours can vary noticeably from one city to the next.

Local Option and Dry Counties

Voters in each county or municipality decide whether to allow alcohol sales at all. Through a local referendum, residents can vote their jurisdiction wet (full retail and on-premises sales permitted) or dry (all sales prohibited).⁷ Some areas sit in the middle, allowing wine in grocery stores or beer sales but not full liquor retail. These partially open jurisdictions are commonly called moist counties, though that isn’t a statutory term.

Local decisions override the general state permissions. Crossing a county line can mean the difference between buying a bottle of whiskey and not finding a single place that sells alcohol. Municipalities with a population of 700 or more can hold their own referendums independently of the surrounding county, which sometimes creates islands of wet territory inside otherwise dry counties.

Open Container and Public Intoxication

Drivers can’t consume alcohol or possess an open container while operating a motor vehicle anywhere in the state. An open container is treated as being in the driver’s possession when no passenger claims it and it isn’t stored in a closed glove compartment, trunk, or another area outside the passenger cabin.⁸ A violation is a Class C misdemeanor, fine only.

Public intoxication is a separate Class C misdemeanor. You can be charged if you appear in a public place under the influence of any intoxicating substance to a degree that you endanger yourself, endanger others or property, or unreasonably annoy people nearby.⁹ Many cities add their own ordinances restricting drinking in parks, on sidewalks, or in entertainment districts outside designated areas.

DUI Limits and Penalties

Tennessee draws the line at a blood alcohol concentration of 0.08% for adult drivers. At or above that level, you’ve committed a per se DUI regardless of whether your driving appeared impaired. Commercial vehicle operators face a stricter 0.04% limit.¹⁰ Impairment from drugs, marijuana, or any combination also counts, so a DUI charge is possible below 0.08% if your ability to drive is compromised.

Fines escalate sharply with each conviction:¹¹

First offense: $350 to $1,500 in fines, a minimum of 48 hours in jail (up to 11 months and 29 days), one-year license revocation, and mandatory roadside litter removal.
Second offense: $600 to $3,500 in fines with increased jail time.
Third offense: $1,100 to $10,000 in fines.
Fourth or subsequent offense: $3,000 to $15,000 in fines.

If a child under 18 is in the vehicle, the court adds $1,000 to the fine at any offense level. The minimum fine is mandatory and can’t be reduced or suspended unless the court specifically finds the defendant is indigent.

High BAC Enhancement

As of July 1, 2025, a first-offense DUI with a BAC of 0.15% or higher triggers enhanced penalties, including a minimum of seven consecutive days in jail rather than 48 hours. Before that date the enhancement threshold was 0.20%. The legislature didn’t add a matching enhancement for second or later offenses, so judges keep broad discretion when sentencing repeat offenders with elevated BAC.

Underage Drivers

Drivers under 21 face a zero-tolerance standard. A BAC of just 0.02% is enough for a charge of underage driving while impaired. For an offender aged 18 to 20, the charge is a Class A misdemeanor carrying a one-year license suspension, a $250 fine, and possible community service. For those under 18, the same penalties apply, but the case is handled as a delinquent act in juvenile court.¹²

Implied Consent and Test Refusal

By driving in Tennessee, you’re deemed to have consented to breath tests, blood tests, or both when a law enforcement officer has probable cause to believe you’ve committed a DUI offense.¹³ Before testing, the officer must warn you that refusal means license revocation.

Refusal is not itself a criminal offense, but the license consequences are steep:¹⁴

No prior conviction: one-year revocation.
Prior conviction: two-year revocation.
Refusal after a crash causing serious bodily injury: two-year revocation.
Refusal after a fatal crash: five-year revocation.

The revocation for refusing runs consecutively with any license suspension from the underlying DUI if the driver has certain prior offenses within five years. In practice, refusing almost always makes the overall license penalty worse, not better.

Boating Under the Influence

Tennessee’s BUI law tracks the DUI statute closely. Operating any vessel on Tennessee waters while impaired is illegal, and a BAC at or above 0.08% is a violation, the same threshold that applies on the road.¹⁵ A BAC of 0.05% or less creates no presumption of impairment, but officers can still bring charges based on observed behavior.

Refusing a chemical test on the water carries a 12-month suspension of boating privileges. Unlike the DUI refusal statute, a BUI refusal is handled by the same court that resolves the underlying boating offense. Commercial vessel operators are held to the stricter 0.04% federal limit on federally controlled waters.

When a Bar or Host Can Be Sued

Tennessee lets injury victims sue alcohol sellers, but the standard of proof is among the toughest in the country. A plaintiff must convince a 12-person jury beyond a reasonable doubt that the sale was the proximate cause of the injury and that the seller either sold to someone known to be under 21 or sold to a visibly intoxicated person.¹⁶ That is the same standard used in criminal trials, which makes these civil claims exceptionally difficult to win. Most states use the lower preponderance-of-the-evidence standard for dram shop cases.

Social hosts get even more protection. State law generally doesn’t impose civil liability on a private individual who furnishes alcohol to an adult guest. The exception involves minors. An adult who permits underage drinking at their home owes a duty of care to those minors, and if an intoxicated minor leaves and causes a crash, the host can be liable for the resulting injuries or deaths, even if the host didn’t personally hand the minor a drink but merely allowed the drinking to happen.
