(c) and (d).

350.095(2)(c) (c) For every snowmobile manufactured after July 1, 1972, and before July 2, 1975, the noise level standard for exhaust and engine noise shall be 90 decibels as measured in accordance with the procedures established for the measurement of exhaust sound levels of stationary snowmobiles in the January 2004 Society of Automotive Engineers Standard J2567.

350.095(2)(d) (d)

350.102(1) (1) Requirement. A person shall provide a sample of his or her breath for a preliminary breath screening test if a law enforcement officer has probable cause to believe that the person is violating or has violated the intoxicated snowmobiling law and if, prior to an arrest, the law enforcement officer requested the person to provide this sample.

350.102(2) (2) Use of test results. A law enforcement officer may use the results of a preliminary breath screening test for the purpose of deciding whether or not to arrest a person for a violation of the intoxicated snowmobiling law or for the purpose of deciding whether or not to request a chemical test under s. 350.104. Following the preliminary breath screening test, chemical tests may be required of the person under s. 350.104.

350.102(3) (3) Admissibility. The result of a preliminary breath screening test is not admissible in any action or proceeding except to show probable cause for an arrest, if the arrest is challenged, or to show that a chemical test was properly required of a person under s. 350.104.
