An act relating to excessive motor vehicle noise

This bill prohibits operating motor vehicles with inadequate or modified exhaust systems, such as those lacking interior baffles, gutted mufflers, or amplification devices, on Vermont highways. It directly affects vehicle owners and drivers by requiring their vehicles to meet specific mechanical noise standards. The law allows exceptions for vehicles used in authorized public racing or speed demonstrations and prevents non-compliant vehicles from passing state inspections. Violations carry escalating civil penalties ranging from $100 for a first offense to $350 for subsequent violations, with the changes taking effect on July 1, 2023.
