(C) Alcohol set point to start vehicle—
1. Have an alcohol set point below twenty-five thousandths
(.025) for initial breath test to start the vehicle;
2. Require the operator to provide a second breath sample
that shall be below the alcohol set point within ten (10)
minutes after the operator’s initial breath sample provided it is
at or above the alcohol set point;
3. Permit a maximum of two (2) attempts to blow a breath
sample below the alcohol set point within a ten- (10-) minute
period;
4. Cause a fifteen- (15-) minute temporary lockout when
two (2) failed startup attempts occur within a ten- (10-) minute
period;
5. Present a violations reset message when two (2) fifteen-
(15-) minute temporary lockouts occur within a thirty- (30-) day
period;
6. Require the manufacturer in the event of two (2) temporary lockout occurrences within a thirty- (30-) day period
to report such occurrences as a violation as required in 7 CSR
60-2.040(4);
(D) Alcohol retest set point and running retest.
1. Provide a running retest feature.
2. Have an alcohol retest set point of twenty-five
thousandths (.025).

the start of the vehicle and randomly during each subsequent
thirty- (30-) minute time period thereafter while the vehicle is
in operation.
4. Activate the vehicle’s horn, or other installed alarm, until
the operator shuts off the engine when a device calculates a
breath sample at or above the alcohol retest set point of twentyfive thousandths (.025) or when a device records a failure to
provide a running retest sample within five (5) minutes.
A. Any aftermarket alarm or siren installed in a vehicle
by the Authorized Service Provider (ASP) will be installed inside
the passenger compartment of the vehicle.
B. Upon request of the driver, aftermarket lighting shall
be installed within the vehicle by the ASP to notify hearing
impaired drivers of a requested breath test. Such lighting shall
be demonstrated to the division upon request.
5. Present a violations reset message when three (3) running retest breath samples at or above the alcohol retest set
point occur within a thirty- (30-) day period or when three (3)
running retest refusals are recorded within a thirty- (30-) day
period;
(E) Violations reset message.
1. Instruct the operator to obtain device service within
seven (7) days following receipt of the message.
2. Cause the vehicle to enter a permanent lockout condition
when a device is not serviced within seven (7) days;
(F) Device calibration.
1. Utilize calibration devices that are listed on the “Highway
Safety Programs; Conforming Products List of Calibrating
Units for Breath Alcohol Testers” established by the United
States Department of Transportation, National Highway Traffic
Safety Administration, 77 FR 64588-64590 as published in the
Federal Register on October 22, 2012 by the National Highway
Traffic Safety Administration, 1200 New Jersey SE, Washington,
DC 20590 and effective October 22, 2012, which are hereby
incorporated by reference and made a part of this rule. This
paragraph does not incorporate any subsequent amendments
or additions to this publication.
2. Calibrate devices at least every thirty (30) days, +/- seven
(7) days, or during each monitoring service.
3. Be calibrated for accuracy by using a wet bath or dry
gas alcohol standard with a reference value between 0.02 and
0.050 g/dL BrAC. The solution or gas should have a certificate of
analysis that is traceable to the National Institute of Standards
and Technology (NIST).
4. The device calibration must be within +/- 0.005 BrAC of
the calibration standard reference value.
5. House and use wet bath simulators in environmentally
stable, temperature controlled settings. Utilize wet bath

digital thermometers and read thirty-four (34) degrees Celsius,
+/- 0.2 degrees Celsius. Tubing length connecting the simulator
to the interlock device will not exceed six (6) inches in length.
6. Store dry gas alcohol standard tanks in an environment
where the temperature range remains between fifty and one
hundred and four (50–104) degrees Fahrenheit and secured in
a manner as to prevent harm to the public. The reference value

or affected by unintended data corruption, low vehicle
battery voltage, loss of power supply, or disengagement or
disconnection of the device.
3. Store data in a manner so that it can be printed in a
report format that can be reasonably understood without
reference to other information or documents.
4. Capture the date and time of any use or attempted use
of a vehicle, any act or attempt to tamper or circumvent the
device, device malfunctions, running retest refusals, when
a violation reset message was presented, and any device
servicing.
5. Capture the date, time, and breath alcohol concentration,
in grams per two hundred ten (210) liters of air, of each breath
sample provided to the device.
6. Provide photo identification or digital images and
global positioning data when the features are enabled as
required by the court supervising authority, Department of
Revenue, or Missouri statute;

person providing a breath sample and his/her position in the
vehicle can be clearly identified.
4. Provide a photo or digital image of sufficient quality
and resolution so that the operator can be clearly identified
in all lighting conditions including but not limited to extreme
brightness, darkness, and low light conditions.
5. Provide a photo or digital image for each successful
completion of the initial breath test, successful completion
of any running retest breath test, unsuccessful delivery of the
initial breath test, unsuccessful delivery of any running retest
breath test, any refusal to take the breath test, and for any
circumvention or tampering.
6. Indicate the date, time, and BrAC reading when the
photo or digital image was taken; and
(I) Real-Time Reporting.
1. Effective on and after January 1, 2019, incorporate realtime reporting capabilities on all new installations of devices
that require a camera by statute or court order.
2. Effective on and after August 1, 2019, incorporate realtime reporting capabilities on all currently installed devices
that require a camera by statute or court order except when
the operator is within three (3) months of removal of the device
unless they have received a violations reset during that time
period.
3. Provide near real-time data transmission between the
operator’s device and the manufacturer’s server while the
device is in use.
4. Make available for viewing, when a violation occurs, all
data, including photos or digital imaging and global positioning
system coordinates, if required, on the manufacturer’s website
within ten (10) minutes from when the data was recorded on
the device or as soon as cellular transmission will permit. This
includes any last event data recorded after power off or as
power is restored (e.g., skipped running retest data).
5. Make available for viewing, during normal operation
without violations, all data, including photos or digital imaging
and global positioning system coordinates, if required, on the
manufacturer’s website within twelve (12) hours from when
the data was recorded on the device or as soon as cellular
transmission will permit. This includes any last event data
recorded after power off or as power is restored (e.g., skipped
running retest data).
6. Provide the date of the last upload on the operator’s web
account.
7. Utilize a cell phone company as well as a cellular
contract that includes roaming services or a data transmission
service. In cases where there is no cellular reception or data
transmission, the device will store the data and send it as soon
as reception is available or restored.
