RI Ignition Interlock

The failed reading is logged and reported to the DMV. Multiple failures or tampering attempts can extend the interlock period, trigger a Traffic Tribunal hearing, or result in additional charges.

Generally no. The interlock requirement applies to every vehicle the offender drives, unless the court makes specific findings allowing operation of an employer's vehicle in the course of employment under § 31-27-2.8(i). Driving any non-equipped vehicle while under interlock order is itself a violation.

When the interlock is used to shorten the suspension, § 31-27-2.8(b) sets 3 months to 1 year for a first offense, 6 months to 2 years for a second offense, and 1 to 4 years for a third offense (felony).

It is mandatory if the BAC was 0.15 or higher under § 31-27-2(d)(1)(iii). For lower BAC tiers, the interlock is discretionary and may or may not be ordered by the sentencing judge.

The ignition interlock cost in Rhode Island is set by the approved vendor, not by statute. The driver pays the installation, monthly monitoring and removal fees out of pocket for as long as the interlock order lasts, so ask the vendor for its current fee schedule before installation.
