Two important parts to consider before your getting nuts. Is your truck rated over 10,000 lbs. This exempts most open trailers with a car. Are you deducting the gas,insurance on vehicle, race car itself and/or maintenance fees? If not then this does not affect you. COMMERCIAL USE is the key factor. If you add your race winnings to your total income and do not use the mentioned above deductions, then you are not affected.If you want to get around this, then have your local U.S. congressman and senator change the laws governing the IRS status of "race cars" and the tax code. The tax laws for racing are so screwy at best. If they change those laws and allow for the deduction on maintenance, then this new mandate of your truck/trailer may be just a little glitch.
