Geoff or others (Geoff I know this thread will get your attention) - I have an F-800 with Air brakes that is legally (registered and actual door plate) 24,500 GVW. I was afraid to have non-cdl drivers in it (including myself), but according to the CT DMV the truck is a commercial vehicle, but no-CDL required unless it hooks up to an over 10,000 lb. trailer. so "your grandmother could drive it". I actually had them get in the truck and inspect it to be sure. Over 18,000, under 26,000 you need a medical card but not a CDL. And, you are supposed to have DOT #s (at least in CT). In fact, a friend just set up a F-650 under CDL with Air Brakes too. Am I missing some info on the regs? Is there a federal law which supercedes a state Regulation, and if so who enforces it? BTW - it has a 10' Fisher, but I don't plow driveways with it, we use the 2.5 yd. wheel loader exclusively for Driveways from now on!!!!!
