When is an ignition interlock required after a Rhode Island DUI?

Under R.I. Gen. Laws § 31-27-2(d)(1)(iii), a first-offense conviction with a BAC of .15 or above (or under the influence of drugs) requires the judge or magistrate to prohibit driving a vehicle not equipped with an ignition interlock and/or blood and urine testing. For first offenses below .15 the court 'may' impose it. Second and subsequent convictions 'shall' carry the prohibition (§ 31-27-2(d)(2)–(3)).

How long does the interlock period last?

R.I. Gen. Laws § 31-27-2.8(b) sets ranges: three months to one year for a first violation of § 31-27-2(d)(1); six months to two years for a second violation (§ 31-27-2(d)(2)) or a first refusal; one to four years for a third violation or second refusal; and two to ten years for a third refusal.

Who issues the interlock restriction and hardship license?

The RI DMV states that 'Only a Rhode Island court can issue a hardship license or ignition interlock restriction upon conviction of an alcohol related offense in accordance with RIGL 31-27-2.8,' and that the DMV 'only ensures that the hardship and interlock restrictions are added to the Rhode Island driver's license.' Under 280-RICR-30-15-9, the DMV places a 'U' restriction on the record and license.

What DMV fees apply after an alcohol-related suspension?

The RI DMV Adjudication Fees table lists License Reinstatement and Refusals (DUI) at $353.50, an Ignition Interlock Device fee of $100.00, Registration Reinstatement at $253.50, and Alcohol Education at $405.00, each including a $3.50 technology surcharge. The DMV's Hardship License Instructions also list a $27.50 fee to update the license with the interlock restriction. The DMV states it does not offer payment plans.

Ignition interlock requirement

Ignition interlock requirements in Rhode Island by offense
Item	Rhode Island rule
IID on first offense	Required only above a high-BAC threshold
Minimum IID period, first offense	3 months to 1 year (first offense under § 31-27-2(d)(1), per § 31-27-2.8(b)(1)); 6 months to 2 years for a first refusal (§ 31-27-2.1(c)(1), per § 31-27-2.8(b)(2))
Minimum IID period, repeat offense	6 months to 2 years (second offense under § 31-27-2(d)(2), per § 31-27-2.8(b)(3)); 1 to 4 years for a second refusal (§ 31-27-2.8(b)(4)); 1 to 4 years for a third or subsequent DUI (§ 31-27-2.8(b)(5))

Threshold: BAC of 0.15 or above (or under the influence of drugs). Under R.I. Gen. Laws § 31-27-2(d)(1)(iii), for a first offense with BAC .15 or above the sentencing judge or magistrate 'shall prohibit that person from operating a motor vehicle ... that is not equipped with an ignition interlock system and/or blood and urine testing as provided in § 31-27-2.8.' For a first offense below .15 (§ 31-27-2(d)(1)(i)–(ii)) the judge or magistrate 'may' impose the interlock (discretionary). Separately, § 31-27-2.8(b) lets any mandatory suspension be reduced 'upon request' by imposition of an interlock, and § 31-27-2.8(c) provides that a hardship license 'shall only be granted in conjunction with the installation of an ignition interlock device and/or blood and urine testing.' The interlock is ordered by the court, not the DMV; the DMV adds the restriction to the license.

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 Rhode Island does, the sources below say so.

The RI DMV's GU-1338 Special Financial Responsibility Insurance Certificate page states: 'Please be advised that Financial Responsibility (SR-22) is no longer required by the State of Rhode Island.' The GU-1338 certificate is required only for certain business plate types and minors registering vehicles; a DUI conviction is not among the listed triggers.
