The bill amends the Michigan Vehicle Code to enhance the authority of peace officers in arresting individuals suspected of operating a vehicle under the influence of alcohol or drugs. Key updates include the introduction of preliminary oral fluid analysis as an additional tool alongside the existing preliminary chemical breath analysis, allowing officers to use results from either test in criminal prosecutions. The bill also establishes that individuals who refuse to submit to these tests may face civil infractions or misdemeanors, and it outlines the procedures for administering these tests, including informing individuals of the consequences of refusal. Additionally, the language throughout the sections has been modified to use gender-neutral terms, and the definition of bodily fluids eligible for testing has been expanded to include blood, breath, urine, and other bodily fluids.

Moreover, the bill specifies that individuals with certain medical conditions, such as hemophilia or diabetes, are not considered to have consented to blood withdrawal. It updates the language regarding the administration of tests to indicate that they "must" be administered as outlined in section 625a(6), replacing the previous wording of "shall." The bill also details the procedures for peace officers when a person refuses a chemical test or when test results are pending, including the immediate confiscation of the individual's driver's license and the issuance of a temporary license. It clarifies definitions related to controlled substances and establishes the validity period for temporary licenses based on prosecution status. The enactment of this bill is contingent upon the passage of House Bill No. 4390.
