§ 11-501.9.
Suspension of driver's license; failure or refusal of validated roadside chemical tests; failure or refusal of field sobriety tests; implied consent. (a) A person who drives or is in actual physical control of a motor vehicle upon the public highways of this State shall be deemed to have given consent to (i) validated roadside chemical tests or (ii) standardized field sobriety tests approved by the National Highway Traffic Safety Administration, under subsection (a-5) of Section 11-501.2 of this Code, if detained by a law enforcement officer who has a reasonable suspicion that the person is driving or is in actual physical control of a motor vehicle while impaired by the use of cannabis. The law enforcement officer must have an independent, cannabis-related factual basis giving reasonable suspicion that the person is driving or in actual physical control of a motor vehicle while impaired by the use of cannabis for conducting validated roadside chemical tests or standardized field sobriety tests, which shall be included with the results of the validated roadside chemical tests and field sobriety tests in any report made by the law enforcement officer who requests the test. The person's possession of a registry identification card issued under the Compassionate Use of Medical Cannabis Program Act alone is not a sufficient basis for reasonable suspicion. For purposes of this Section, a law enforcement officer of this State who is investigating a person for an offense under Section 11-501 of this Code may travel into an adjoining state where the person has been transported for medical care to complete an investigation and to request that the person submit to field sobriety tests under this Section. (b) A person who is unconscious, or otherwise in a condition rendering the person incapable of refusal, shall be deemed to have withdrawn the consent provided by subsection (a) of this Section. (c) A person requested to submit to validated roadside chemical tests or field sobriety tests, as provided in this Section, shall be warned by the law enforcement officer requesting the field sobriety tests that a refusal to submit to the validated roadside chemical tests or field sobriety tests will result in the suspension of the person's privilege to operate a motor vehicle, as provided in subsection (f) of this Section. The person shall also be warned by the law enforcement officer that if the person submits to validated roadside chemical tests or field sobriety tests as provided in this Section which disclose the person is impaired by the use of cannabis, a suspension of the person's privilege to operate a motor vehicle, as provided in subsection (f) of this Section, will be imposed. (d) The results of validated roadside chemical tests or field sobriety tests administered under this Section shall be admissible in a civil or criminal action or proceeding arising from an arrest for an offense as defined in Section 11-501 of this Code or a similar provision of a local ordinance. These test results shall be admissible only in actions or proceedings directly related to the incident upon which the test request was made. (e) If the person refuses validated roadside chemical tests or field sobriety tests or submits to validated roadside chemical tests or field sobriety tests that disclose the person is impaired by the use of cannabis, the law enforcement officer shall immediately submit a sworn report to the circuit court of venue and the Secretary of State certifying that testing was requested under this Section and that the person refused to submit to validated roadside chemical tests or field sobriety tests or submitted to validated roadside chemical tests or field sobriety tests that disclosed the person was impaired by the use of cannabis. The sworn report must include the law enforcement officer's factual basis for reasonable suspicion that the person was impaired by the use of cannabis. (f) Upon receipt of the sworn report of a law enforcement officer submitted under subsection (e) of this Section, the Secretary of State shall enter the suspension to the driving record as follows: (1) for refusal or failure to complete validated roadside chemical tests or field sobriety tests, a 12-month suspension shall be entered; or (2) for submitting to validated roadside chemical tests or field sobriety tests that disclosed the driver was impaired by the use of cannabis, a 6-month suspension shall be entered. The Secretary of State shall confirm the suspension by mailing a notice of the effective date of the suspension to the person and the court of venue. However, should the sworn report be defective for insufficient information or be completed in error, the confirmation of the suspension shall not be mailed to the person or entered to the record; instead, the sworn report shall be forwarded to the court of venue with a copy returned to the issuing agency identifying the defect. (g) The law enforcement officer submitting the sworn report under subsection (e) of this Section shall serve immediate notice of the suspension on the person and the suspension shall be effective as provided in subsection (h) of this Section. If immediate notice of the suspension cannot be given, the arresting officer or arresting agency shall give notice by deposit in the United States mail of the notice in an envelope with postage prepaid and addressed to the person at his or her address as shown on the Uniform Traffic Ticket and the suspension shall begin as provided in subsection (h) of this Section. The officer shall confiscate any Illinois driver's license or permit on the person at the time of arrest. If the person has a valid driver's license or permit, the officer shall issue the person a receipt, in a form prescribed by the Secretary of State, that will allow the person to drive during the period provided for in subsection (h) of this Section. The officer shall immediately forward the driver's license or permit to the circuit court of venue along with the sworn report under subsection (e) of this Section. (h) The suspension under subsection (f) of this Section shall take effect on the 46th day following the date the notice of the suspension was given to the person. (i) When a driving privilege has been suspended under this Section and the person is subsequently convicted of violating Section 11-501 of this Code, or a similar provision of a local ordinance, for the same incident, any period served on suspension under this Section shall be credited toward the minimum period of revocation of driving privileges imposed under Section 6-205 of this Code.
