Where each company can install in North Dakota
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 (Intoxalock, LifeSafer, RoadGuard), pulled Oct 2026. Some shops serve more than one company. Alcohol Detection Systems doesn't publish a locator we could read.
