Mississippi DUI Penalties & Costs
A DUI conviction in Mississippi costs far more than the fine amount listed in the statute. Court costs, assessments, program fees, insurance increases, and license reinstatement fees add up quickly. This page breaks down the full financial picture.

The True Cost of a First-Offense DUI
The statutory fine is only a fraction of the total cost. Here is a typical breakdown for a first-offense DUI in Mississippi:
Insurance Impact
A DUI conviction typically results in a significant auto insurance rate increase. In Mississippi, drivers convicted of DUI are generally required to file an SR-22 certificate of financial responsibility for approximately 3 years.
- Insurance premiums commonly increase 50% to 200% or more after a DUI conviction.
- Some insurers will drop coverage entirely, forcing you to find a high-risk carrier.
- The SR-22 requirement itself adds administrative costs and must be maintained continuously — a lapse can restart your suspension period.
- The insurance impact is often the single largest financial consequence of a DUI.
Ignition Interlock Device Costs
For second and subsequent offenses (and sometimes first offenses with high BAC), Mississippi may require an ignition interlock device (IID). Typical costs:
- Installation: $70 – $150
- Monthly rental/monitoring: $60 – $90 per month
- Removal: $50 – $100
- Calibration (periodic): $25 – $50 per visit
- Total for a 1-year IID requirement: approximately $900 – $1,400
