Mississippi requires ignition interlock devices for most hardship license holders. Installation runs $70–$150, monthly monitoring $60–$90, and removal $50–$100—total first-year cost often exceeds $1,000.
What Mississippi Charges for IID on a Hardship License
Mississippi hardship license holders pay three separate IID fees: installation ($70–$150), monthly monitoring ($60–$90), and removal ($50–$100). The court order or DMV suspension notice determines your IID duration, not the hardship license itself. Most drivers are required to maintain the device for 90 days minimum on a first DUI, but subsequent offenses or aggravating factors push that to 1–3 years.
Monitoring fees are your ongoing cost. At $75/month average, a 90-day requirement costs $225 in monitoring alone. A one-year requirement costs $900. Installation and removal add another $120–$250 to the total. Budget $500–$1,200 for a 90-day requirement and $1,200–$1,500+ for a full year.
The device must stay installed for the entire court-ordered period, even if your hardship license expires earlier or you regain full driving privileges. Removing it early resets your compliance clock to zero and typically results in immediate hardship license revocation.
Who Installs IID Devices in Mississippi and What They Charge
Mississippi-approved IID providers include Smart Start, Intoxalock, LifeSafer, and Guardian Interlock. Installation costs vary by provider and location but typically range $70–$150. The provider drills into your ignition system, calibrates the device, and trains you on breath submission protocol. Most installations take 60–90 minutes.
Monthly monitoring includes device calibration every 30 days, data download, and compliance reporting to the Mississippi Department of Public Safety. Miss a calibration appointment and the device locks you out after 7 days in most cases. The provider reports the missed appointment to DPS, which can trigger hardship license suspension.
Removal fees run $50–$100 once your court-ordered IID period ends and you receive written confirmation from DPS or the court. Do not remove the device based on your own calendar. Removal without written clearance is treated as noncompliance and extends your requirement.

How IID Duration Affects Your Total Mississippi Hardship License Cost
Your total IID cost depends entirely on how long the court or DMV orders you to maintain it. Mississippi law sets a 90-day minimum for first-offense DUI hardship licenses, but judges routinely order 6 months to 1 year, especially if your BAC was .15 or higher or if a minor was in the vehicle. Second and third offenses carry 1–3 year IID requirements.
A 90-day requirement costs approximately $500 total: $100 installation, $225 monitoring (3 months at $75), and $75 removal. A one-year requirement costs approximately $1,200–$1,500: $100 installation, $900–$1,080 monitoring (12 months at $75–$90), and $100 removal. Add $200–$400 more if you miss calibration appointments and incur lockout fees or device reset charges.
The hardship license application itself costs $100 in Mississippi, plus $50 reinstatement fee when you transition back to a full license. Combined with SR-22 insurance premiums (typically $40–$80/month added cost for high-risk drivers), your first-year compliance cost often runs $2,000–$3,500.
SR-22 Requirement Runs Parallel to IID on Mississippi Hardship Licenses
Mississippi requires SR-22 filing for the entire hardship license period and typically for 3 years total from your DUI conviction date. The SR-22 is a liability insurance endorsement filed by your carrier directly with the Mississippi Department of Public Safety. It proves you carry at least state minimum liability: $25,000 bodily injury per person, $50,000 per accident, and $25,000 property damage.
SR-22 insurance does not cost extra as a filing fee (most carriers charge $15–$25 per year to file the form), but your underlying auto insurance premium increases 70–150% after a DUI conviction. Expect to pay $120–$200/month for SR-22 liability coverage as a hardship license holder, compared to $50–$80/month for clean-record drivers in Mississippi. That premium stays elevated until the violation drops off your record, typically 3–5 years.
Non-standard carriers that write hardship license SR-22 policies in Mississippi include Bristol West, Direct Auto, Dairyland, GAINSCO, The General, and Safe Auto. Progressive and GEICO may also write you but typically at higher rates than your pre-conviction premium. Expect quotes from 4–6 carriers before finding the lowest rate.
What Happens If You Miss an IID Calibration or Violate Device Terms
Mississippi IID devices require calibration every 30 days. The device warns you 5–7 days before the deadline. If you miss the appointment, the device enters lockout mode after 7 days in most cases, preventing the vehicle from starting. The provider reports the missed appointment to DPS within 48 hours, and DPS typically suspends your hardship license within 10 business days.
Violations include failed breath tests (BAC above .02), missed rolling retests while driving, or tampering with the device. A single failed test does not automatically revoke your hardship license, but the data downloads to DPS at each calibration. Three failed tests in a 30-day period typically triggers a violation notice and hardship license review hearing. Tampering or attempting to bypass the device results in immediate hardship license revocation and extension of your IID requirement by 6–12 months.
Lockout fees run $50–$100 to reset the device after a missed calibration. If your hardship license is suspended for noncompliance, you restart the entire application process, pay another $100 hardship license fee, and the court may extend your IID requirement. Budget 60–90 days to regain driving privileges after a compliance suspension.
Mississippi Hardship License Eligibility and IID Interaction
Mississippi allows hardship license applications 30 days after a DUI suspension begins for first offenders, or 90 days for second offenses. You must show proof of enrollment in an alcohol safety education program, proof of SR-22 insurance, proof of IID installation (if required by your court order), and a letter from your employer stating your need to drive for work.
The hardship license restricts you to driving for employment, medical appointments, education, and court-ordered program attendance only. The Department of Public Safety issues the license with specific approved hours and routes based on your employer letter. Driving outside those hours or for non-approved purposes is a misdemeanor and results in immediate hardship license revocation.
IID must remain installed for the court-ordered period even after your hardship license ends. If you were ordered to maintain IID for 1 year but your hardship license was only approved for 6 months, the device stays in your vehicle until the full year is complete. Removing it early resets your IID clock and delays full license reinstatement.
