(a) If a law enforcement officer has reasonable suspicion to believe that a person is violating or has violated Section 11-501 or a similar provision of a local ordinance, the officer, prior to an arrest, may request the person to provide a sample of his or her breath for a preliminary breath screening test using a portable device approved by the Illinois State Police. The person may refuse the test. The results of this preliminary breath screening test may be used by the law enforcement officer for the purpose of assisting with the determination of whether to require a chemical test as authorized under Sections 11-501.1 and 11-501.2, and the appropriate type of test to request. Any chemical test authorized under Sections 11-501.1 and 11-501.2 may be requested by the officer regardless of the result of the preliminary breath screening test, if probable cause for an arrest exists. The result of a preliminary breath screening test may be used by the defendant as evidence in any administrative or court proceeding involving a violation of Section 11-501 or 11-501.1.
(b) The Illinois State Police shall create a pilot program to establish the effectiveness of pupillometer technology (the measurement of the pupil’s reaction to light) as a noninvasive technique to detect and measure possible impairment of any person who drives or is in actual physical control of a motor vehicle resulting from the suspected usage of alcohol, other drug or drugs, intoxicating compound or compounds or any combination thereof. This technology shall also be used to detect fatigue levels of the operator of a Commercial Motor Vehicle as defined in Section 6-500(6), pursuant to Section 18b-105 (Part 395-Hours of Service of Drivers) of the Illinois Vehicle Code. A State Police officer may request that the operator of a commercial motor vehicle have his or her eyes examined or tested with a pupillometer device. The person may refuse the examination or test. The State Police officer shall have the device readily available to limit undue delays.
If a State Police officer has reasonable suspicion to believe that a person is violating or has violated Section 11-501, the officer may use the pupillometer technology, when available. The officer, prior to an arrest, may request the person to have his or her eyes examined or tested with a pupillometer device. The person may refuse the examination or test. The results of this examination or test may be used by the officer for the purpose of assisting with the determination of whether to require a chemical test as authorized under Sections 11-501.1 and 11-501.2 and the appropriate type of test to request. Any chemical test authorized under Sections 11-501.1 and 11-501.2 may be requested by the officer regardless of the result of the pupillometer examination or test, if probable cause for an arrest exists. The result of the examination or test may be used by the defendant as evidence in any administrative or court proceeding involving a violation of 11-501 or 11-501.1.
The pilot program shall last for a period of 18 months and involve the testing of 15 pupillometer devices. Within 90 days of the completion of the pilot project, the Illinois State Police shall file a report with the President of the Senate and Speaker of the House evaluating the project.
