Bill > HB4390

This bill expands Michigan's vehicle code to include "other bodily fluid" as a method of testing for intoxication or impairment, specifically focusing on oral fluid tests. The bill modifies definitions and provisions related to commercial driver's licenses, allowing peace officers (instead of only certified drug recognition experts) to conduct preliminary oral fluid analyses to detect the presence of controlled substances. The changes impact how the Secretary of State handles license suspensions and revocations, particularly for commercial drivers who refuse chemical tests or are found responsible for certain traffic violations. The bill broadens the types of bodily fluids that can be used for testing from blood, breath, and urine to now include oral fluid and other bodily fluids capable of revealing the presence of controlled substances or their metabolites. The amendments apply to various scenarios involving commercial motor vehicle operation, including serious traffic violations, alcohol-related offenses, and instances of refusing chemical testing. The bill will take effect 90 days after enactment and is contingent on the passage of a related House Bill (HB 4391).
