(2) (c) or, at his or her own expense, reasonable opportunity to have any qualified person administer a chemical test of his or her breath, blood or urine for the purpose of authorized analysis.

30.684(3)(b) (b) Optional test. If a person is arrested for a violation of the intoxicated boating law and if the person is not requested to provide a sample or to submit to a test under sub.

Results of these chemical tests shall be given the effect required under s. 885.235. This section does not limit the right of a law enforcement officer to obtain evidence by any other lawful means.

30.684(5) (5) Refusal. No person may refuse a lawful request to provide one or more samples of his or her breath, blood or urine or to submit to one or more chemical tests under sub. (1). A person shall not be deemed to refuse to provide a sample or to submit to a chemical test if it is shown by a preponderance of the evidence that the refusal was due to a physical inability to provide the sample or to submit to the test due to a physical disability or disease unrelated to the use of an intoxicant. Issues in any action concerning violation of sub. (1) or this subsection are limited to:

30.684(5)(a) (a) Whether the law enforcement officer had probable cause to believe the person was violating or had violated the intoxicated boating law.
