What Mississippi law requires

Mississippi's ignition interlock, SR-22, and reinstatement rules are set by the statute and agency rules cited below. The values in the tables on this page are taken from those sources and are not interpretations of how they apply to any particular case.

Primary source: Miss. Code Ann. § 63-11-31

Ignition interlock requirement

For a first DUI conviction or nonadjudication, Miss. Code Ann. § 63-11-23(5) suspends the license for 120 days unless the person obtains an interlock-restricted license or the court orders the person to drive only under an interlock-restricted license. The Driver Service Bureau describes the first-offense outcome as either a 120-day suspension or a 120-day restriction with an ignition-interlock device. The court decides whether to order the interlock-restricted license; it is not mandatory for every first offender.

Removal: Compliance-based, with proof submitted to the Department of Public Safety and the court able to extend the period. Full rule and source

SR-22 requirement

An SR-22 is a certificate an insurer files with the state to confirm that a driver carries the liability coverage the state requires. Some states use an FR-44 or a different form for alcohol-related offenses; where Mississippi does, the sources below say so.

Miss. Admin. Code Title 31, Part 1, Rule 16.1 requires proof of financial responsibility (high-risk insurance, SR-22 or the like) in effect for not less than three years for reinstatement after an Implied Consent suspension, citing Miss. Code Ann. § 63-15-61. The Driver Service Bureau states first-offense reinstatement requires MASEP completion and proof of insurance for three years.
