Primary source: Nev. Rev. Stat. § 484C.460
Ignition interlock requirement
| Item | Nevada rule |
|---|---|
| IID on first offense | Required |
| Minimum IID period, first offense | 185 days |
| Minimum IID period, repeat offense | 1 year (second violation within 7 years); 3 years for felony DUI or DUI causing death/substantial bodily harm |
NRS 484C.460(1)(a) requires the court to order a person convicted of a first DUI violation within 7 years (NRS 484C.110) to install an ignition interlock device, at the person's own expense, in any vehicle the person operates as a condition of obtaining an ignition interlock privilege under NRS 483.490, for 185 days. NRS 484C.460(2) lets the court except a first offender who cannot provide a deep-lung breath sample (physician/APRN certification) or who lives more than 100 miles from a manufacturer or its agent. Separately, NRS 484C.210(3) requires a driver under a 185-day administrative (per se 0.08) revocation to install an interlock to obtain an interlock privilege; the DMV describes this as an early-reinstatement option.

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 Nevada does, the sources below say so.
| SR-22 filing required after a DUI | Yes |
|---|---|
| Filing period | 3 years |
SR-22. The Nevada DMV states an SR-22 Certificate of Liability Insurance must be maintained for 3 years (36 consecutive months); the three-year period begins upon reinstatement of the Nevada license, a lapse restarts the three years, and an SR-22 obtained before reinstatement does not count.
