Who has to install one in Nevada
Program run by: Nevada Committee on Testing for Intoxication (NV State Police Office of Traffic Safety); DMV handles license side · agency page
Law: NRS 484C.320 et seq. (cite from memory, unverified); NAC 484C.160 (device standards, NHTSA spec) · read it
For the rule that applies to you, read your court order or the letter from the DMV.
A judge can order an interlock in other cases too. Your court order or DMV letter is what binds you.
Where each company can install in Nevada
You'll go back to the same company's locations for service for the whole order, so check that one is close to where you live and work before you book.
Locations as each company lists them on its own locator (Smart Start, Intoxalock, LifeSafer, Low Cost Interlock, RoadGuard), pulled Oct 2026. Some shops serve more than one company. Alcohol Detection Systems doesn't publish a locator we could read.

From the state's approved list (read it). Use a company on this list, or the install won't count. 12-month figures are lease, install and removal from each company's filed or published fee schedule, not Nevada prices; see how we add them up.
