AS per one standard across the US--"be carefull what you wish for." Because of the Interstate Commerce clause in our constitution Congress and the feds set Interstate rules for Tracter trailers. To have them jump into the regulation of Motorhome/trailer rigs used by racers may have many other consequences i.e.CDL requirements for all, stopping at all weight scales etc.
It appears the issue has only surfaced in a handfull of states. I suggest that we racers contact a friend in our respective state legislatures and seek a resolution using the North Carolina model. State legislatures belong to a national association and have access to codes in all states. We have statistics on our side as fortunately few race rigs are envolved in major accidents. Track operators and motor sports councils (if your state has one) are good allies. Don't forget the circle track guys who (while lacking focus and a since of directiion) use a lot of big race rigs. former state senator- Mike Withers
