Recognizing the Protection of Motorsports Act of 2018 (RPM Act)

The RPM Act is common-sense, bi-partisan legislation to protect law-abiding citizens who convert cars, trucks and motorcycles into racing vehicles.  The bill clarifies that it has always been legal to make emissions-related changes to a street vehicle that has been converted into a racecar used exclusively in competition.  It also confirms that it is legal to produce, market and install racing equipment.  

In July 2015, the EPA issued a proposed regulation declaring that the Clean Air Act prohibits converting a motor vehicle into a racecar.  Manufacturing, selling and installing race parts for the converted vehicle would also be a violation.  Although the EPA did not finalize the proposed rule, the agency stands by this interpretation.  SEMA contends it contradicts 45 years of previous EPA practice. 

Converting street vehicles into dedicated race vehicles is an American tradition dating back decades which has negligible environmental impact.  While California is known for having the strictest emissions laws, the state exempts racing vehicles from regulation. 

There are about 1,300 race tracks across the country.  Most cater to thousands of organized amateur racing events which involve converted vehicles.  These drivers, race teams and spectators—all help drive local economies.  They fill up motel rooms and restaurants, shop at local stores.  These activities translate into tens of thousands of jobs and billions of dollars in economic activity, including about $1.6 billion in annual sales of racing equipment. 

The RPM Act does not interfere with the EPA’s authority to enforce against individuals who illegally install race parts on vehicles driven on public roads and highways and the companies that market such products.  This is called tampering and is a clear violation of the Clean Air Act.

The RPM Act will provide the racing community with certainty and confidence in the face of an EPA regulatory action that threatens to devastate an American pastime and eliminate jobs in our communities. 

Tell Your Elected Officials to Protect Motorsports and Pass the RPM Act


Recently, the House Energy & Commerce Subcommittee on Environment passed the RPM Act.  Republicans and Democrats alike expressed a desire to provide certainty to racers and the motorsports parts industry. However, there is much more to be done before the RPM Act becomes law.

Use our Action Center to send a message to your Senators and Representative to ask them to support the RPM Act.
