The fees nobody quotes you over the phone
These are charged on top of the three above, and they are where a cheap-looking Mississippi quote turns expensive.
| Fee | Amount |
|---|---|
| State ignition-interlock fee (paid when you collect the license) | $175 |
| Ignition-interlock-restricted driver license | $56 |
| Reinstatement to a regular license afterwards | $175 |
- These are state charges on top of whatever your provider bills for the device itself.
What Mississippi requires
Mississippi treats the interlock as the way to keep driving at all. The license is seized at the stop and the paper receipt works as a permit for 30 days; after that an administrative suspension runs unless the court has ordered an interlock-restricted license instead. Refusing the chemical test suspends a Class R license for 90 days on its own, and a year if you have a prior.
- First offense: Set by the court order for an interlock-restricted license, which is what avoids the administrative suspension in the first place
- Lockout threshold: Set by the approved device; the interlock-restricted license is issued on a court order
- Program run by: Mississippi Department of Public Safety, on the court order
Why Mississippi 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. Neshoba County runs above the Mississippi average, which is part of why the interlock requirement here is enforced the way it is. 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 Philadelphia
Where can I get an ignition interlock device installed in Philadelphia, MS?
We index 2 certified installation points in Philadelphia, run by Low Cost 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 Mississippi?
Mississippi does not publish provider prices — they are set by the approved provider, not by the state. Nationally, nHTSA puts installation at $70 to $90 and monitoring at about $70 a month, roughly $3 to $4 a day. The state publishes only its own charges: State ignition-interlock fee (paid when you collect the license) $175, Ignition-interlock-restricted driver license $56, Reinstatement to a regular license afterwards $175. Quotes in Philadelphia will sit around that unless the provider is charging for something the state does not require.
Can I drink one beer and still start the car in Mississippi?
Almost certainly not. Mississippi 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.
