Is there an Illinois law that states classic cars can have loud exhaust?

There is no Illinois state law that explicitly allows classic cars to have loud exhaust. However, there are several regulations and laws that outline the maximum noise levels that vehicles are permitted to emit. It is important to note that these regulations may vary depending on the location and specific vehicle type.

According to the Illinois Vehicle Code, Section 12-288, "No person shall drive a motor vehicle with any equipment so designed or so used as to emit excessive or unusual noise." This section provides a general prohibition against excessive noise from any motor vehicle.

In addition, the Illinois Environmental Protection Agency (IEPA) has specific noise pollution regulations that apply to vehicles, including classic cars. These regulations set limits on the maximum sound levels that vehicles are allowed to emit. The IEPA also has the authority to issue permits for certain vehicles, including classic cars, that may exceed these limits.

Therefore, while there is no specific Illinois law that states that classic cars can have loud exhaust, it is important to comply with the general noise regulations and laws outlined by the state and the IEPA to avoid potential fines or penalties for excessive noise.
