The RV Industry Association (RVIA) has clarified that its seal signifies members' self-certification to adopted standards for the living quarters portion of RVs and participation in annual unannounced audits. The vehicle portion of both towable and motorized RVs is regulated by the National Highway Traffic Safety Administration (NHTSA) under Federal Motor Vehicle Safety Standards (FMVSS). RVIA does not inspect or enforce FMVSS but requires members to provide NHTSA registration documentation and offers educational seminars on compliance. The RVIA seal indicates voluntary adherence to additional standards for electrical, plumbing, heating, and fire safety.
