What New Hampshire requires

New Hampshire runs the program through the DMV and the courts together: a court or the Commissioner of Safety orders the device, and you may drive only vehicles fitted with a New Hampshire-approved one. The certificate of installation goes to the DMV yourself, not through the vendor. If you cannot afford it, RSA 265-A:36 allows a hearing for a credit of up to 75% of installation and service costs.

  • First offense: Ordered by a New Hampshire court or by the Commissioner of Safety under RSA 265-A:36; you may only drive vehicles fitted with a NH-approved device
  • Lockout threshold: Set by the preset level in the approved device: RSA 259:43-a defines it as blocking the engine unless the sample is below that level
  • Program run by: NH Division of Motor Vehicles, or the court

Why New Hampshire orders these devices

An interlock order is not a judgment about you personally — it is what the state does with every case of this kind, and the reason sits in the crash record.

Cheshire County, 2020–2022

Source: NHTSA Fatality Analysis Reporting System, 2020–2022. The count covers fatal crashes where police recorded that a driver had been drinking, which is narrower than the federal 0.08 BAC measure and therefore understates the real figure. Cheshire County runs at or below the New Hampshire average — the requirement is set state-wide regardless. What the device changes is measurable too: a car fitted with one cannot be started over the limit, which is why the order attaches to driving privileges rather than to the sentence.

Questions

Interlock questions in Keene

Where can I get an ignition interlock device installed in Keene, NH?

We index 3 certified installation points in Keene, run by Intoxalock, Smart Start, RoadGuard Interlock. Addresses are listed above. Book with the provider your paperwork names, not the nearest one — a device approved in one state is not automatically approved in the next, and switching brands mid-term means a second installation fee.

How much does it cost to have an ignition interlock device installed in New Hampshire?

New Hampshire does not publish a price, so the honest answer is the national one: NHTSA puts installation at $70 to $90 and monitoring at about $70 a month, roughly $3 to $4 a day. Quotes in Keene will sit around that unless the provider is charging for something the state does not require.

Can I drink one beer and still start the car in New Hampshire?

Almost certainly not. New Hampshire does not print one fixed number in the statute — the level is set by the certifying agency in the device standard, typically between 0.02% and 0.025% BAC, far below the 0.08% driving limit. The device is not testing whether you are impaired, it is testing whether you drank. One drink shortly before a test is enough on most programs, and the fail is recorded whether or not you try again.

What does an ignition interlock device do?

An ignition interlock is a breath-alcohol tester wired into your car ignition. You blow into it before starting the engine; if your breath alcohol is above the state threshold, the engine will not start.

While you are driving, the device asks for rolling retests at random intervals. Every sample, skipped test, and lockout is recorded and sent to the agency monitoring your case.
