NAC484C.170. Calibration, testing and examination; requirements; tampering.

     1. Each device that prevents an intoxicated person from starting a vehicle must be calibrated, tested and examined by the manufacturer or his or her agent at least once every 90 days.

     2. The calibration must include:

     (a) Verification by the manufacturer or his or her agent of the response and accuracy of the device at no less than two levels of alcohol, within the range that corresponds to a concentration of alcohol in the breath of 0.02 to 0.10 grams, inclusive, of alcohol per 210 liters of breath. The accuracy of the device must be within 10 percent of the value of the standard alcohol solution for each level.

     (b) The response of the device to breath samples that do not contain alcohol.

     (c) Verification that the device prevents the motor vehicle in which it is installed from starting if the concentration of alcohol in a person’s breath is equal to or greater than 0.02 grams of alcohol per 210 liters of breath.

     3. Each device must meet the following requirements established by the Committee:

     (a) Ability to sample a minimum volume of expired breath that is required to test a person’s breath;

     (b) Ability to test a minimum concentration of alcohol in the breath that is required to prevent the motor vehicle from starting and a minimum concentration of alcohol in the breath that is required for subsequent tests of the person’s breath while the person is driving the motor vehicle;

     (c) Requirements for calibrating a device before installation;

     (d) Options for restricting the hours of operation of the vehicle;

     (e) The frequency with which the device will require a person’s breath to be tested while driving the motor vehicle; and

     (f) The ability of the device to prevent a person who has the device installed in his or her motor vehicle from starting the vehicle if the person:

          (1) Fails to submit the device for a mandatory calibration;

          (2) Tampers with the device; or

          (3) Receives a result on the test of the person’s breath that is at or above a prohibited level.

     4. If any evidence of tampering with the device is found, the device must not be used.
