A DUI conviction in Tennessee hits your wallet harder than most people expect. The court-ordered fine is only the starting point. When you add up insurance increases, ignition interlock fees, license reinstatement costs, lost wages, and attorney fees, even a first-offense DUI can cost well over $10,000.
If you’ve been arrested for DUI in Memphis or anywhere in Tennessee, here’s what you’re actually looking at financially, broken down by offense.
Court-Ordered Fines by Offense Level
Tennessee Code Annotated § 55-10-403 sets mandatory fine ranges for DUI convictions. These minimums cannot be reduced or suspended unless the court determines you are indigent.
- 1st offense: $350 to $1,500
- 2nd offense (within 10 years): $600 to $3,500
- 3rd offense (within 10 years): $1,100 to $10,000
- 4th or subsequent offense (Class E felony): $3,000 to $15,000
If a child under 18 was in the vehicle at the time of the offense, Tennessee law adds a mandatory $1,000 to any of those fines (TCA § 55-10-403(a)(1)(B)).
These are just the base fines. Court costs, fees, and surcharges can add $500 to $1,000+ on top.
Additional Mandatory Fees
Beyond the fine itself, Tennessee law imposes several additional costs on every DUI conviction under TCA § 55-10-413:
- Alcohol and Drug Addiction Treatment (ADAT) fee: $100
- Blood Alcohol Concentration (BAC) test fee: Assessed per conviction
- Ignition interlock fee: Assessed when a restricted license with IID is ordered
- Court costs and litigation tax: Varies by county, typically $250 to $500+
These fees are not optional. They are tacked on automatically by the court.
Ignition Interlock Device (IID) Costs
Under TCA § 55-10-417, many DUI offenders are required to install an ignition interlock device on every vehicle they own or operate. For second and subsequent offenses, interlock is mandatory.
Here’s what IID costs typically look like:
- Installation: $100 to $225
- Monthly lease, monitoring, and calibration: $70 to $125 per month
- Annual administrative fee: $12.50
- Program development fee (for restricted license applicants): Set by the court
Over the course of one year, total interlock costs often exceed $1,000 to $1,500. If your revocation period is two years or more, that number doubles.
SR-22 Insurance and Higher Premiums
After a DUI conviction, Tennessee requires you to file an SR-22 certificate of financial responsibility before your license can be reinstated. You must maintain SR-22 coverage for three to five years.
The SR-22 filing itself typically costs $15 to $50, but the real cost is the insurance premium increase. A DUI moves you into high-risk driver territory.
- Average annual insurance cost after a Tennessee DUI: Roughly $2,000+
- Typical increase over pre-DUI rates: 40% to 80% or more
- Duration of increased rates: 3 to 5+ years
Over three years, the insurance impact alone could cost $3,000 to $6,000+ compared to what you were paying before.
License Reinstatement Fees
Getting your license back after a DUI revocation involves multiple steps and fees:
- Reinstatement fee: $65 to $100
- SR-22 filing fee: $50
- Failure-to-surrender fee (if applicable): $75
- Possible written and/or road skills test fees
Tennessee also requires proof of DUI school completion and, in many cases, an alcohol and drug assessment before reinstatement is approved.
DUI School and Alcohol Assessment Costs
Under TCA § 55-10-402, every DUI conviction requires participation in an alcohol and drug safety DUI school and/or a drug and alcohol assessment. Courts may also require treatment.
- DUI school: Typically $150 to $300
- Alcohol and drug assessment: $100 to $250
- Treatment program (if ordered): $500 to $5,000+, depending on type and duration
If the court orders inpatient treatment, the cost can climb significantly higher.

- Bail/bond fees: $500 to $5,000+, depending on the charge and county
- Towing and vehicle impound fees: $200 to $500+
- Lost employment or reduced job prospects: A DUI can disqualify you from jobs requiring driving, security clearances, or professional licenses
- CDL revocation: Commercial drivers face a one-year disqualification for a first DUI and lifetime disqualification for a second
- Child custody complications: Family courts may view a DUI as a factor in custody decisions
- Vehicle seizure and forfeiture: Tennessee law allows seizure of vehicles used in a second or subsequent DUI (TCA § 55-10-414)
