Policy Position

The United States has a 50-state patchwork of exhaust noise laws, with every state having its own metric for determining whether a car is too loud. Many states have subjective laws that say a car is too loud if it makes "excessive noise" without defining what that means. When states enact overly vague or poorly worded laws pertaining to vehicle noise, it can have a chilling impact on the ability of SEMA members that produce aftermarket exhaust products to sell and install their products. On the other hand, California has implemented SEMA's model legislation, which sets a limit of 95 decibels using an objective testing method to determine if a car is too loud. SEMA supports this model and advocates that other states adopt similar laws regarding noise ordinances.

Noise cameras are an emerging technology that's increasingly used to determine whether a vehicle is in compliance. SEMA has raised concerns about this technology and does not support its premature implementation for two reasons. First, like a red light camera, these noise cameras take photos when a vehicle is above the specified decibel level. However, if multiple cars are simultaneously on the road, there is no definitive way to determine which car is in violation. This can result in unfair ticketing of drivers. Secondly, when implemented in urban areas, tall buildings can reflect and amplify the sound, making it even more challenging to determine if a vehicle is in violation.

SEMA supports further research into this technology and believes that it should only be introduced once all the concerns associated with the pilot are addressed.

Policy Position

The Car Allowance Rebate System (CARS), better known as "cash for clunkers," was a 2009 Federal program that provided financial incentivizes for people to trade in older cars and purchase new vehicles.

SEMA wants to ensure that no similar incentives would compel people to destroy or trade in their old. The aftermarket, restoration market, auto enthusiasts, and millions of Americans rely on older vehicles for their professions, recreation, and affordable transportation. While there are no introduced bills that currently provide similar incentives, SEMA will proactively fight for this to remain the case and for older vehicles to be kept on the road.

Conversely, SEMA supports legislation that incentivizes preserving old cars or upcycling. SEMA is sponsoring a California bill that provides a rebate of up to $4,000 for those who convert an existing internal-combustion car or truck to an EV. This rebate allows older vehicles to stay on the road while ensuring technological advancements.
