| Temporary lockout code | up to $25 |
| Annual administrative fee | $12.50 |

What Tennessee requires
Tennessee runs the program through the court: you need an Order for Restricted Driver License signed by a judge before any provider will fit the device, plus SR-22 insurance. The order is also what the provider uses to calculate how long you serve, so the paperwork sets the clock.
- First offense: Set by the court order for a restricted license (form ORDL signed by the judge), which the provider uses to calculate your time in the program
- Lockout threshold: Set by the preset limit in the certified device: the state defines it as blocking the vehicle at or above that reading
- Program run by: The sentencing court, with the restricted license issued by TN Department of Safety
Why Tennessee orders these devices
An interlock order is not a judgment about you personally — it is what the state does with every case of this kind, and the reason sits in the crash record.
Source: NHTSA Fatality Analysis Reporting System, 2020–2022. The count covers fatal crashes where police recorded that a driver had been drinking, which is narrower than the federal 0.08 BAC measure and therefore understates the real figure. Marshall County runs at or below the Tennessee average — the requirement is set state-wide regardless. What the device changes is measurable too: a car fitted with one cannot be started over the limit, which is why the order attaches to driving privileges rather than to the sentence.

Interlock questions in Lewisburg
Where can I get an ignition interlock device installed in Lewisburg, TN?
We index 1 certified installation point in Lewisburg, run by RoadGuard Interlock, Smart Start. Addresses are listed above. Book with the provider your paperwork names, not the nearest one — a device approved in one state is not automatically approved in the next, and switching brands mid-term means a second installation fee.
How much does it cost to have an ignition interlock device installed in Tennessee?
Tennessee publishes its own figures rather than leaving it all to vendors: up to $225 to fit the device and up to $125 a month while it stays on the car, and the monthly figure is a ceiling an approved provider may not exceed. Removal is billed separately at the end of the term.
Can I drink one beer and still start the car in Tennessee?
Almost certainly not. Tennessee does not print one fixed number in the statute — the level is set by the certifying agency in the device standard, typically between 0.02% and 0.025% BAC, far below the 0.08% driving limit. The device is not testing whether you are impaired, it is testing whether you drank. One drink shortly before a test is enough on most programs, and the fail is recorded whether or not you try again.
What does an ignition interlock device do?
An ignition interlock is a breath-alcohol tester wired into your car ignition. You blow into it before starting the engine; if your breath alcohol is above the state threshold, the engine will not start.
While you are driving, the device asks for rolling retests at random intervals. Every sample, skipped test, and lockout is recorded and sent to the agency monitoring your case.
