What is the maximum allowable noise level from a vehicle’s exhaust system during inspection?

The maximum allowable noise level from a vehicle’s exhaust system is established to ensure that vehicles operate within acceptable limits that minimize noise pollution and contribute to road safety. A noise level of 95 decibels is the standard limit set for vehicle exhaust systems during inspections. This level is significant as it aligns with regulations designed to protect both public health and the environment.

Maintaining such a threshold helps to reduce the risk of excessive noise that may contribute to hearing loss in surrounding populations and create disturbances in residential areas. While it is important for vehicles to operate effectively, managing noise levels is equally essential for contributing to a more peaceful urban and suburban experience. Thus, vehicles exceeding this noise level may require repairs to their exhaust systems to meet compliance.
