Mississippi Administrative Code › Title 31 - Public Safety › Part 505 - CRIME LAB - IGNITION INTERLOCK DEVICE PROGRAM › Chapter 3 - Ignition Interlock Device Requirements › Rule 31-505-3.1 - Ignition Interlock Device Requirements

Current through June 25, 2024
The ignition interlock device must be tested by an
				  independent alcohol testing laboratory, and the results submitted to the MSDPS
				  with all costs of the test being the responsibility of the manufacturer or
				  service provider. All ignition interlock devices must, at a minimum, meet or
				  exceed the United States Department of Transportation, National Highway Traffic
				  Safety Administration (NHTSA) specifications as published in the Federal
				  Register Volume 78, Number 89, Wednesday, May 8, 2013 pages 26849 26876. In
				  addition to the NHTSA specifications any proposed IID must be based upon
				  electro-chemical fuel cell sensor technology. These specifications include, but
				  are not limited to the following:
1.
				The ignition interlock device shall be able to analyze a specimen of alveolar
				breath for alcohol concentration.
2. The ignition interlock device shall
				indicate when a sufficient sample of breath has been collected and shall
				indicate this by audible or visual means.
3. The results of the test shall be noted
				through the use of pass/fail signals. There shall be no numerical BrAC level
				displayed.
4. The ignition
				interlock device shall lockout a driver when an alcohol concentration of .02
				grams of alcohol/210 liters or higher of breath is detected.
5. The ignition interlock device shall have
				the ability to detect and record attempts to tamper, alter, or bypass the
				device and any violations such as an alcohol concentration of above 0.02 grams
				of alcohol/210 liters of breath (BrAC).
6. The ignition interlock device shall have
				the ability to prevent operation of the motor vehicle by a participant who
				fails to retest or fails to appear at a scheduled monitoring
				appointment.
7. The ignition
				interlock device shall issue a warning of an impending lockout.
8. The ignition interlock device must be
				capable of random re-testing and timed re-testing. A subsequent breath test
				will be conducted within 5 minutes after starting the vehicle and every 30
				minutes while the vehicle is in operation. During the rolling retest, the
				retest set point shall be the same as the startup set point. A warning light
				and/or tone shall alert the driver of 5 minutes until retest. If the engine is
				shut down after or during the 5 minute warning but before retesting, the retest
				clock shall not be reset.
9. The
				startup set point value for the interlock device shall be an alcohol
				concentration of 0.02 g/210 liters of breath. The accuracy of the device shall
				be plus or minus 0.005 g/210 liters of breath.
10. A negative breath alcohol test shall
				enable the ignition relay. The IID shall allow two (2) minutes from the time
				the ignition is enabled to start the vehicle. In the event of a stall, the
				device will allow the vehicle to be restarted within two (2) minutes without a
				retest.
11. If the initial test
				results in a lockout is due to the operator's BrAC level, the device shall not
				allow an additional attempt for fifteen (15) minutes. If the operator's BrAC
				remains too high, the machine shall lockout for an additional fifteen (15)
				minutes.
12. Failure to take a
				retest is a violation and is recorded by the device.
13. If the result of the retest is higher
				than the fail point, the device shall enter the violation lockout which shall
				be reported to the MSDPS by the service provider.
14. The ignition interlock device must be
				capable of thwarting attempts at evasion or circumvention with the use of bogus
				or filtered breath.
15. The IID
				shall have the following operational features:
a. The device shall be designed to permit a
				free restart of a motor vehicle's ignition within two (2) minutes after the
				ignition has been shut off, without requiring a further alcohol
				analysis.
b. The device shall also
				automatically purge alcohol before allowing subsequent analyses.
c. The device shall have a data storage
				system of sufficient capacity to record and maintain all daily driving
				activities for the 30 day monitoring period.
