The result of this preliminary breath screening test may be used by the law enforcement officer for the purpose of deciding whether or not the person shall be arrested for a violation of s. 346.63 (1), (2m), (5) or (7) or a local ordinance in conformity therewith, or s. 346.63 (2) or (6), 940.09 (1) or 940.25 and whether or not to require or request chemical tests as authorized under s. 343.305 (3).

Following the screening test, additional tests may be required or requested of the driver under s. 343.305 (3). The general penalty provision under s. 939.61 (1) does not apply to a refusal to take a preliminary breath screening test.
