HB 6151 modifies Michigan's vehicle code to adjust how noise violations are classified and penalized, directly affecting vehicle owners and dealers. The bill establishes that certain noise infractions will be treated as civil offenses with fines ranging from $500 to $1,000, while other specific violations remain misdemeanors with higher penalties. It also clarifies that dealers who knowingly install non-compliant exhaust systems are liable for fines and legal fees if a customer receives a citation. Additionally, the legislation updates record-keeping requirements for courts to ensure detailed reports on vehicle noise violations are sent to the secretary of state.
