Yes. The benefits of refusing the PBT outweigh the risks of consenting to a PBT. Refusal to take the PBT is a civil infraction and does not result in points or license sanctions (unlike refusing a DataMaster Test). The civil infraction is punishable only by a fine of one hundred dollars. MCL 257.625a(2)(d).
On the other hand, the results of the PBT test may give the police probable cause to arrest you, and it arms the police with a more objective measure to prove intoxication than the standard field sobriety tests. The police may still find probable cause through their subjective observations of the field sobriety tests, so there is no reason to give them “extra ammunition” by way of the objective PBT. The benefits of denying this piece of evidence outweigh the risks of incurring a civil infraction for refusing to take the PBT.
