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.

Exemptions and special cases
Four questions readers ask once an interlock is ordered — motorcycles, employer vehicles, medical inability to give a breath sample, and reduced-cost programs — answered as Nevada's interlock program page or statute states them.
| Question | Nevada rule |
|---|---|
| Motorcycles | Not addressed on the official pages read NRS 484C.460 and NRS 484C.210 require the device 'in any motor vehicle which the person operates' and do not mention motorcycles; the DMV DUI page, the DMV Suspensions/Revocations & Reinstatement page (Ignition Interlock Devices section) and the DMV restriction-code list do not address motorcycles. |
| Employer-owned vehicle | Exempt with conditions Under NRS 484C.460(5), a person required to operate a motor vehicle in the course and scope of employment may operate an employer-owned vehicle without a device if the employee notifies the employer that an ignition interlock privilege has been issued and has proof of that notification in his or her possession or the notice (or a facsimile copy) is with the vehicle. The exemption does not apply to a vehicle owned by a business that is all or partly owned or controlled by the person. What the source says“(a) The employee notifies his or her employer that the employee has been issued an ignition interlock privilege; and (b) The employee has proof of that notification in his or her possession or the notice, or a facsimile copy thereof, is with the motor vehicle.” |
| Unable to provide a breath sample | Available For a first misdemeanor DUI, NRS 484C.460(2) lets the court provide an exception to the interlock order if the person is unable to provide a deep lung breath sample as certified in writing by a physician or advanced practice registered nurse (or resides more than 100 miles from a manufacturer or its agent). For the administrative revocation, NRS 484C.210(4) lets the DMV provide an exception and issue a restricted license under NRS 483.490(1) on the same grounds if the person is not a repeat intoxicated driver as defined in 23 C.F.R. 1275.3(k). What the source says“if the court determines that: (a) The person is unable to provide a deep lung breath sample for analysis by an ignition interlock device, as certified in writing by a physician or an advanced practice registered nurse of the person” |
| Reduced-cost / indigent program | Available NRS 484C.480(1)(d) requires Department of Public Safety regulations that make the manufacturer or its agent waive the cost of installing or removing the device and adjust the lease, calibration or monitoring fee: to 50 percent of the fee for a person with income at or below 100 percent of the federal poverty level, and to 75 percent of the fee for a person who receives supplemental nutritional assistance, was determined indigent under NRS 171.188, or has income at or below 149 percent of the federal poverty level. The statute does not name the program; the DMV pages do not describe it. What the source says“if the person required to install an ignition interlock device pursuant to NRS 484C.210 or 484C.460: (1) Has an income which is at or below 100 percent of the federally designated level signifying poverty, to 50 percent of the fee” |
| Distance exception (more than 100 miles from a provider) | The same court (NRS 484C.460(2)(b)) and DMV (NRS 484C.210(4)(b)) exceptions also apply where the person resides more than 100 miles from a manufacturer of an ignition interlock device or its agent. What the source says“(b) The person resides more than 100 miles from a manufacturer of an ignition interlock device or its agent.” |
| Employer exemption - excluded vehicles | The employer-vehicle exemption does not apply to a vehicle owned by a business all or partly owned or controlled by the person subject to the interlock requirement. What the source says“This exemption does not apply to a motor vehicle owned by a business which is all or partly owned or controlled by the person otherwise subject to this section.” |
| Reduced fee - 75 percent tier | The second tier of NRS 484C.480(1)(d) adjusts the fee to 75 percent for SNAP recipients, persons found indigent under NRS 171.188, or income at or below 149 percent of the poverty level. What the source says“(2) Receives supplemental nutritional assistance, as defined in NRS 422A.072, was determined indigent pursuant to NRS 171.188 or has an income which is at or below 149 percent of the federally designated level signifying poverty, to 75 percent of the fee.” |
| DMV restriction Y | The DMV issues a license with Restriction Y after proof of installation; the DMV describes the interlock as an early reinstatement option for DUI-related suspensions and states that once reinstated with an interlock the person is no longer eligible to request an administrative hearing on the revocation. What the source says“DMV will issue a license with Restriction Y after proof of installation and meeting other requirements.” |
