www.DIESELmotorsports.US without permission

October 2007, DIESEL Motorsports (NADM) the only legal sanctioning body for diesels was founded with the purpose and vision of unifying and solidifying the diesel industry via sanctioned events and promotional support of all racing sanctioning bodies, organizations, clubs, manufacturers, vendors and individual enthusiasts. DIESEL Motorsports will petition industry leaders in the diesel aftermarket for guidance insuring progressive growth, expansion, and prosperity for the industry's future. DIESEL Motorsports promotions will culminate in the offering of DIESEL Motorsports sanctioned events including diesel drag racing and sled pulls. In cooperation with existing diesel organizations, DIESEL Motorsports will compliment the existing schedules and help coordinate a nation-wide diesel event schedule. This event calendar is open to all organizations seeking to advertise their events and will be hosted on the DIESEL Motorsports website. Further goals include the support or sponsorship of events throughout the country via existing organizations. The goal of DIESEL Motorsports is not to supply every diesel event in the country, but assist in promotion of diesel events on a national level. Competitive class structures and rules for DIESEL MOTORSPORTS sanctioned events are in this rulebook, and will remain for the season. Should the need arise for an amendment; all competition members will be notified in writing via e-mail. Rule set goals are to promote safety, provide a competitive field that allows participants to easily compete in multiple organizations and support efforts to stabilize existing rule sets. DIESEL Motorsports has formed an official "Advisory Panel" of the association. This panel will be composed of elected DIESEL Motorsports business members that will represent all areas of member interest. All media and photographers must obtain permission to be on tracks during events and all photos, videos and media become the property of DIESEL Motorsports. DIESEL Motorsports has the rights to use the media, photographs and video taken during events of competitors to further promote sponsors, events and DIESEL Motorsports.
