Again here are some of the issues that exist for racers. There is the Fed law and then there are the state laws. Fed laws are uniform throughout the 50 states. State laws vary according to each state. For racers the problem arises-are you racing for money doing it as a business. Other than professional teams the feds and states look for tell tale signs. First, does the car, trailer, motorhome or tow vehicle have lettering that indicates a business venture...Bob's Texaco, Silver Plating Inc., High Flying Cuda etc. If you get pulled over and they ask you to open the enclosed trailer, will they find a lettered car. The old sign"NOT FOR HIRE " is not antedote for being pulled over. The follow up is, if you are given a citation you may need to prove to the contrary. As per the IRS... 8,000.00 in car expenses and only a $50.00 check for round money makes you a business. IRS rules about auto racing are very screwy. In the state of PA only state troopers were allowed to pull over and cite trucks, truck/trailers. Now local townships can do this if there are trained. As I said before, this is a real money maker for local government. As you go through different townships on your way to race, look for police cars that are stationed near turnpikes and major roads. They are usually looking for tractor trailers, flat bed tow trucks and P.O.S. There are usually posts on line when there is a large race reminding drivers to be updated with driver regs. Does this mean that everyone will be stopped? No. But government is always hungry for $. Things have really changed. SEMA is working on this issue for motorhomes. Racers as a group in general need to work together on this issue. This is not to scare anyone. Just info that needs to be known
