Upon a positive test administered under subpart 2 of a motorcycle road guard, or a test refusal of a motorcycle road guard, a peace officer shall:
When the commissioner is notified under subpart 3 that a person who holds a motorcycle road guard certificate has violated this part or that a person who holds a motorcycle road guard certificate has refused a test under subpart 2, the commissioner shall:
For purposes of this part, "reason to believe" means from the manner in which a motorcycle road guard is driving, operating, controlling, or acting upon departure from a motor vehicle, or has driven, operated, or controlled a motor vehicle, or grounds put forth in good faith which are not arbitrary, irrational, unreasonable, or irrelevant and which make the proposition asserted more likely than not. Grounds upon which reason to believe are based include:
