.02 Definitions.

A. In this chapter, the following terms have the meanings indicated.

B. Terms Defined.

(1) "Administration" means the Motor Vehicle Administration.

(2) "Administrator" means the Administrator of the Motor Vehicle Administration.

(3) "Alcohol" means the generic class of organic compounds known as alcohols and, specifically, the chemical compound ethyl alcohol. For the purpose of ignition interlock devices, there is no requirement expressed or implied that the device be specific for ethyl alcohol.

(4) "Alcohol concentration" (BAC) means the amount of alcohol in a person's blood or breath determined by chemical analysis, which shall be measured by grams of alcohol per:

(a) 100 milliliters of blood; or

(b) 210 liters of breath.

(5) "Alveolar air" (also called "deep lung air") means an air sample which is the last portion of a prolonged, uninterrupted exhalation and which gives a quantitative measurement of alcohol concentration from which blood alcohol concentration can be determined. The alveoli are the smallest air passages in the lungs, surrounded by capillary blood vessels and through which an interchange of gases occurs during respiration. Alcohol in the blood is eliminated from the lungs via the alveoli.

(6) "Approved service provider" has the meaning stated in Transportation Article, §16-404.1, Annotated Code of Maryland.

(7) "BAC" in this chapter means either breath alcohol concentration or blood alcohol concentration.

(8) "Device" or "ignition interlock device" means an ignition interlock system as defined in Transportation Article, §21.902.2, Annotated Code of Maryland.

(9) "Interlock" means the mechanism by which a motor vehicle is prevented from starting when the test result of a person's breath alcohol analysis exceeds a preset BAC level.

(10) "Manufacturer" means any person engaged in the manufacturing or assembling of ignition interlock devices.

(11) "Monitoring" means the approved service provider's action of downloading the information obtained in the device's data logging mechanism and submitting this information to the Administration for review.

(12) "Program" means the Ignition Interlock System Program established by the Administration under Transportation Article, §16.404.1, Annotated Code of Maryland.

(13) "Purge" means the process by which a device cleanses or removes a previous breath test sample from the device and specifically removes residual alcohol.

(14) "Security" means the protection and safeguards incorporated into ignition interlock devices to ensure proper performance and to ensure against failure caused either by inherent defects or human tampering which causes the device not to operate as designed.
