(1)    Definitions. In this section:

     (b)    “Drive” means the exercise of physical control over the speed and direction of a motor vehicle while it is in motion.

     (c)    “Operate” means the physical manipulation or activation of any of the controls of a motor vehicle necessary to put it in motion.

   (2)   Implied consent. Any person who is on duty time with respect to a commercial motor vehicle or drives or operates a motor vehicle upon the public highways of this state, or in those areas enumerated in s. 346.61, is deemed to have given consent to one or more tests of his or her breath, blood or urine, for the purpose of determining the presence or quantity in his or her blood or breath, of alcohol, controlled substances, controlled substance analogs or other drugs, or any combination of alcohol, controlled substances, controlled substance analogs and other drugs, when requested to do so by a law enforcement officer under sub. (3) (a) or (am) or when required to do so under sub. (3) (ar) or (b). Any such tests shall be administered upon the request of a law enforcement officer. The law enforcement agency by which the officer is employed shall be prepared to administer, either at its agency or any other agency or facility, 2 of the 3 tests under sub. (3) (a), (am), or (ar), and may designate which of the tests shall be administered first.

   (3)   Requested or required.

     (a)    Upon arrest of a person for violation of s. 346.63 (1), (2m) or (5) or a local ordinance in conformity therewith, or for a violation of s. 346.63 (2) or (6) or 940.25, or s. 940.09 where the offense involved the use of a vehicle, or upon arrest subsequent to a refusal under par. (ar), a law enforcement officer may request the person to provide one or more samples of his or her breath, blood or urine for the purpose specified under sub. (2). Compliance with a request for one type of sample does not bar a subsequent request for a different type of sample.

     (am)    Prior to arrest, a law enforcement officer may request the person to provide one or more samples of his or her breath, blood or urine for the purpose specified under sub. (2) whenever a law enforcement officer detects any presence of alcohol, a controlled substance, a controlled substance analog or other drug, or a combination thereof, on a person driving or operating or on duty time with respect to a commercial motor vehicle or has reason to believe the person is violating or has violated s. 346.63 (7). Compliance with a request for one type of sample does not bar a subsequent request for a different type of sample. For the purposes of this paragraph, “law enforcement officer” includes inspectors in the performance of duties under s. 110.07 (3).

     (ar)   

        1.    If a person is the operator of a vehicle that is involved in an accident that causes substantial bodily harm, as defined in s. 939.22 (38), to any person, and a law enforcement officer detects any presence of alcohol, a controlled substance, a controlled substance analog or other drug, or a combination thereof, the law enforcement officer may request the operator to provide one or more samples of his or her breath, blood, or urine for the purpose specified under sub. (2). Compliance with a request for one type of sample does not bar a subsequent request for a different type of sample. A person who is unconscious or otherwise not capable of withdrawing consent is presumed not to have withdrawn consent under this subdivision and one or more samples specified in par. (a) or (am) may be administered to the person. If a person refuses to take a test under this subdivision, he or she may be arrested under par. (a).

        2.    If a person is the operator of a vehicle that is involved in an accident that causes the death of or great bodily harm to any person and the law enforcement officer has reason to believe that the person violated any state or local traffic law, the officer may request the operator to provide one or more samples of his or her breath, blood, or urine for the purpose specified under sub. (2). Compliance with a request for one type of sample does not bar a subsequent request for a different type of sample. A person who is unconscious or otherwise not capable of withdrawing consent is presumed not to have withdrawn consent under this subdivision and one or more samples specified in par. (a) or (am) may be administered to the person. If a person refuses to take a test under this subdivision, he or she may be arrested under par. (a).

     (b)    A person who is unconscious or otherwise not capable of withdrawing consent is presumed not to have withdrawn consent under this subsection, and if a law enforcement officer has probable cause to believe that the person has violated s. 346.63 (1), (2m) or (5) or a local ordinance in conformity therewith, or s. 346.63 (2) or (6) or 940.25, or s. 940.09 where the offense involved the use of a vehicle, or detects any presence of alcohol, controlled substance, controlled substance analog or other drug, or a combination thereof, on a person driving or operating or on duty time with respect to a commercial motor vehicle or has reason to believe the person has violated s. 346.63 (7), one or more samples specified in par. (a) or (am) may be administered to the person.

     (c)    This section does not limit the right of a law enforcement officer to obtain evidence by any other lawful means.

   (4)   Information. At the time that a chemical test specimen is requested under sub. (3) (a), (am), or (ar), the law enforcement officer shall read the following to the person from whom the test specimen is requested:

   “You have either been arrested for an offense that involves driving or operating a motor vehicle while under the influence of alcohol or drugs, or both, or you are the operator of a vehicle that was involved in an accident that caused the death of, great bodily harm to, or substantial bodily harm to a person, or you are suspected of driving or being on duty time with respect to a commercial motor vehicle after consuming an intoxicating beverage.

   This law enforcement agency now wants to test one or more samples of your breath, blood or urine to determine the concentration of alcohol or drugs in your system. If any test shows more alcohol in your system than the law permits while driving, your operating privilege will be suspended. If you refuse to take any test that this agency requests, your operating privilege will be revoked and you will be subject to other penalties. The test results or the fact that you refused testing can be used against you in court.

   If you take all the requested tests, you may choose to take further tests. You may take the alternative test that this law enforcement agency provides free of charge. You also may have a test conducted by a qualified person of your choice at your expense. You, however, will have to make your own arrangements for that test.

   If you have a commercial driver license or were operating a commercial motor vehicle, other consequences may result from positive test results or from refusing testing, such as being placed out of service or disqualified.”

   (5)   Administering the test; additional tests.

     (a)    If the person submits to a test under this section, the officer shall direct the administering of the test. A blood test is subject to par. (b). The person who submits to the test is permitted, upon his or her request, the alternative test provided by the agency under sub. (2) or, at his or her own expense, reasonable opportunity to have any qualified person of his or her own choosing administer a chemical test for the purpose specified under sub. (2). If the person has not been requested to provide a sample for a test under sub. (3) (a), (am), or (ar), the person may request a breath test to be administered by the agency or, at his or her own expense, reasonable opportunity to have any qualified person administer any test specified under sub. (3) (a), (am), or (ar). The failure or inability of a person to obtain a test at his or her own expense does not preclude the admission of evidence of the results of any test administered under sub. (3) (a), (am), or (ar). If a person requests the agency to administer a breath test and if the agency is unable to perform that test, the person may request the agency to perform a test under sub. (3) (a), (am), or (ar) that it is able to perform. The agency shall comply with a request made in accordance with this paragraph.

     (b)    Blood may be withdrawn from the person arrested for violation of s. 346.63 (1), (2), (2m), (5) or (6) or 940.25, or s. 940.09 where the offense involved the use of a vehicle, or a local ordinance in conformity with s. 346.63 (1), (2m) or (5), or as provided in sub. (3) (am) or (b) to determine the presence or quantity of alcohol, a controlled substance, a controlled substance analog or any other drug, or any combination of alcohol, controlled substance, controlled substance analog and any other drug in the blood only by a physician, registered nurse, medical technologist, physician assistant or person acting under the direction of a physician.

     (c)    A person acting under par. (b), the employer of any such person and any hospital where blood is withdrawn by any such person have immunity from civil or criminal liability under s. 895.53.

     (d)    At the trial of any civil or criminal action or proceeding arising out of the acts committed by a person alleged to have been driving or operating a motor vehicle while under the influence of an intoxicant, a controlled substance, a controlled substance analog or any other drug, or under the influence of any combination of alcohol, a controlled substance, a controlled substance analog and any other drug, to a degree which renders him or her incapable of safely driving, or under the combined influence of an intoxicant and any other drug to a degree which renders him or her incapable of safely driving, or having a prohibited alcohol concentration, or alleged to have been driving or operating or on duty time with respect to a commercial motor vehicle while having an alcohol concentration above 0.0 or possessing an intoxicating beverage, regardless of its alcohol content, or within 4 hours of having consumed or having been under the influence of an intoxicating beverage, regardless of its alcohol content, or of having an alcohol concentration of 0.04 or more, the results of a test administered in accordance with this section are admissible on the issue of whether the person was under the influence of an intoxicant, a controlled substance, a controlled substance analog or any other drug, or under the influence of any combination of alcohol, a controlled substance, a controlled substance analog and any other drug, to a degree which renders him or her incapable of safely driving or under the combined influence of an intoxicant and any other drug to a degree which renders him or her incapable of safely driving or any issue relating to the person’s alcohol concentration. Test results shall be given the effect required under s. 885.235.

     (e)    At the trial of any civil or criminal action or proceeding arising out of the acts committed by a person alleged to have been driving or operating a motor vehicle while having a detectable amount of a restricted controlled substance in his or her blood, the results of a blood test administered in accordance with this section are admissible on any issue relating to the presence of a detectable amount of a restricted controlled substance in the person’s blood. Test results shall be given the effect required under s. 885.235.

   (6)   Requirements for tests.

     (a)    Chemical analyses of blood or urine to be considered valid under this section shall have been performed substantially according to methods approved by the laboratory of hygiene and by an individual possessing a valid permit to perform the analyses issued by the department of health services. The department of health services shall approve laboratories for the purpose of performing chemical analyses of blood or urine for alcohol, controlled substances or controlled substance analogs and shall develop and administer a program for regular monitoring of the laboratories. A list of approved laboratories shall be provided to all law enforcement agencies in the state. Urine specimens are to be collected by methods specified by the laboratory of hygiene. The laboratory of hygiene shall furnish an ample supply of urine and blood specimen containers to permit all law enforcement officers to comply with the requirements of this section.

     (b)    The department of transportation shall approve techniques or methods of performing chemical analysis of the breath and shall:

        1.    Approve training manuals and courses throughout the state for the training of law enforcement officers in the chemical analysis of a person’s breath;

        2.    Certify the qualifications and competence of individuals to conduct the analysis;

        3.    Have trained technicians, approved by the secretary, test and certify the accuracy of the equipment to be used by law enforcement officers for chemical analysis of a person’s breath under sub. (3) (a), (am), or (ar) before regular use of the equipment and periodically thereafter at intervals of not more than 120 days; and

        4.    Issue permits to individuals according to their qualifications.
