PURPOSE: This rule defines the terms used in the breath alcohol ignition interlock device certification and operational requirements.

1. (1) Definitions.

   1. (A) The following words and terms as used in 7 CSR 60-2.010 through 7 CSR 60-2.060 have the following meaning:

      1. 1. Alcohol retest setpoint—The breath alcohol concentra-

tion at which the ignition interlock device is set for the running retest;

1. 2. Alcohol setpoint—The breath alcohol concentration at

which the ignition interlock device prevents the vehicle from starting;

1. 3. Alveolar air—Deep lung air or alveolar breath, which is

the last portion of a prolonged, uninterrupted exhalation;

1. 4. Authorized service provider (ASP)—The entity designated

by the manufacturer to provide services to include but not be limited to installation, monitoring, maintenance, and removal of the breath alcohol ignition interlock device;

1. 5. Bogus breath sample—Any sample other than an

unaltered, undiluted, and unfiltered alveolar air sample from a driver;

1. 6. Breath alcohol concentration (BrAC)—The amount of

alcohol in a given amount of breath, expressed in weight per volume (% weight/volume) based on grams of alcohol per two hundred ten (210) liters of breath;

1. 7. Breath alcohol ignition interlock device (BAIID)—A

breath testing device, including all parts necessary for operation, e.g., handset and camera, installed in a vehicle that prevents it from operating if breath test results show a BrAC that meets or exceeds the alcohol setpoint. The device also requires the driver to continue to pass repeated breath tests while the vehicle is running to ensure that the driver remains below the alcohol setpoint. However, the interlock device will not interfere with the normal operation of the vehicle while it is in use;

1. 8. Breath—Expired human breath containing primarily

alveolar air;

1. 9. Calibration—The process which ensures an accurate

alcohol concentration reading on a device;

1. 10. Camera—A feature of the device that incorporates

photo identification or digital images of the person who is providing the breath test;

1. 11. Circumvention—To bypass the correct operation of

a BAIID by starting the vehicle by any means without first providing a breath test;

1. 12. Commission—The Missouri Highways and Transporta-

tion Commission created by article IV, section 29, Constitution of Missouri;

1. 13. Department—The Missouri Department of Transporta-

tion created by article IV, section 29, Constitution of Missouri;

1. 14. Designated monitoring period—The period of

time indicated by the Department of Revenue for required monitoring of the driver’s ignition interlock use by the manufacturer;

1. 15. Device—Breath alcohol ignition interlock device;
2. 16. Division—The Highway Safety and Traffic Division

under the department that is delegated the authority to administer the provisions of 7 CSR 60-2.010 through 7 CSR 60- 2.060;

1. 17. Download—The transfer of information from the

interlock device’s memory onto disk or other electronic or digital transfer protocol;

1. 18. Emergency service—Unforeseen circumstances in the

use and/or operation of a breath alcohol ignition interlock device, not covered by training or otherwise documented, which requires immediate action;

1. 19. Filtered breath sample—A breath sample which has

been filtered through a substance in an attempt to remove alcohol from the sample;

1. 20. Global positioning system (GPS)—A feature of the

device that will log the location (longitude and latitude), date, and time of each breath sample including any refusal, any circumvention attempt, and any attempt to tamper with the ignition interlock device;

1. 21. Initial breath test—A breath test required to start a

vehicle to ensure that the driver’s BrAC is below the alcohol setpoint;

1. 22. Installation—Mechanical placement and electrical

connection of a breath alcohol ignition interlock device in a vehicle by a technician;

1. 23. ISO—International Organization for Standardization;
2. 24. Lockout—A condition of the device which prevents

a vehicle’s engine from starting unless it is serviced or recalibrated;

1. 25. Manufacturer—A person or company responsible for

the design, construction, and/or production of a BAIID;

1. 26. Mechanical override code—Method of overriding the

breath sample requirement during the mechanical servicing of a vehicle by a mechanic utilizing a unique code provided by the manufacturer;

1. 27. Mobile service—A portable operation of an authorized

service provider, whether contained within a vehicle or temporarily erected on location, which includes all personnel and equipment necessary to conduct ignition interlock device related business and services, separately and simultaneously with its parent fixed location service centers. The mobile service center shall comply with all of the requirements provided for an authorized service provider herein;

1. 28. Operator—Any person who operates a vehicle that has

a court-ordered or Department of Revenue-required breath alcohol ignition interlock device installed;

1. 29. Override lockout code—Method of overriding a lockout

condition by providing a unique code;

1. 30. Permanent lockout—A condition in which the device

will not accept a breath test until serviced by an ASP;

1. 31. Pure breath sample—Expired human breath containing

primarily alveolar air and having a breath alcohol concentration below the alcohol setpoint of twenty-five thousandths (.025);

1. 32. Real-time reporting—The near real-time transmission

of ignition interlock data between the manufacturer’s server and the operator’s ignition interlock while the device is in use;

1. 33. Refusal—The failure of a driver to provide a breath

sample and complete the breath test when prompted by the device;

1. 34. Relative within second degree of consanguinity or

affinity—A spouse or domestic partner, parent, step-parent, child, step-child, grandparent, step-grandparent, grandchild, step-grandchild, brother, step-brother, sister, step-sister, mother-in-law, father-in-law, grandparent-in-law, grandchildin-law, brother-in-law, or sister-in-law;

1. 35. Retest—Two (2) additional chances to provide a breath

sample below the alcohol setpoint when the first sample failed; or three (3) chances to provide a breath alcohol sample below the alcohol setpoint on the running retest;

1. 36. Running retest—A subsequent breath test that must be

conducted within five (5) minutes after starting the vehicle and randomly during each subsequent thirty- (30-) minute time period thereafter while the vehicle is in operation;

ignition interlock device that occurs when the operator fails to have the device serviced during a certain period of time and results in a permanent lockout condition;

1. 38. Start or starting—To manipulate a vehicle’s inputs or

systems or to activate a motor, thereby initiating the transition of a stationary vehicle into motor-powered, driver-controlled motion;

1. 39. Tampering—An overt, purposeful attempt to physically

alter or disable an ignition interlock device, or disconnect it from its power source, or remove, alter, or deface physical antitampering measures, so a driver can start the vehicle without taking and passing an initial breath test and/or blocking, moving, or disabling the camera, if required;

1. 40. Technician—A person trained by the authorized service

provider to possess the skills necessary to install, service, calibrate, and/or remove ignition interlock devices;

1. 41. Temporary lockout—A condition in which the device

will not allow the vehicle to start for fifteen (15) minutes after two (2) failed attempts to blow a pure breath sample within a ten- (10-) minute period; and
