TriHonu, every thing you say is correct, but I would like to add that is not just Mn. everything you posted if federal. That is the law all over the US. state and local laws might even add to these, but these are federal laws at minimum. one thing you didn't cover was any combination of vehicles rated over 10,000 lbs. used commercially, meaning ANY compensation or pay, falls under the rules of the federal highway motor carrier administration. What that means is for anyone who receives any form of payment for using the equipment being hauled you are considered as a commercial vehicle and you have to play by the same rules as someone who drives for a living. That includes complying with keeping and obeying hours of service regulations, 1 million dollar liability insurance on tow vehicle, driver qualification file, vehicle inspection and maintenance records, the list goes on. You might say it doesn't apply to what you or I do, but if you get paid in any way, it does. I went threw this in a different way but the rules are the same. I had a dirt race car. The motor carrier inspectors where and still do target racers because we are considered a commercial motor carrier, that is because we got prize money (compensation) for racing. Never mind it may well cost you $200 a night to race and you might get back only $100 or so, it's still considered pay. Racing is a hobby (a expensive one) but you technically get "paid" to do it. The exact same thing with your skid steer movements, you go do work for some one and get ANY pay, you are now a commercial motor vehicle. I can't tell you all the rules and regs, and I drive truck commercially for over 30 years. I just suggest everyone learns about this stuff before something happens not only can it make a bad day talking to a motor carrier enforcement officer, if you get in a wreck (not necessarily even your fault) they WILL crawl up your butt looking at your records and qualifications. Here is a link to the the FMCSA site, it's a confusing and frustrating site but all the rules are in there, just hard to find, http://www.fmcsa.dot.gov/mission/about-us
