Interstate Driving Rules and Regs. One man's view.
The following information is based on my own research of the appropriate laws and regulations, several conversations with people at the Federal Motor Carrier Safety Administration at their offices in Texas and Missouri, as well as the main office. I also had several conversations with several different Texas DPS officers that work in Commercial Vehicle Enforcement. The following is what I understand to be required, of me, in my situation, to be in compliance with the law.
My situation: I own a farm in Missery (on the map it appears to be spelled Missouri, but if you have ever lived here…

) I also now own a farm in Paradise (on the map it appears to be spelled Texas

). I own the truck in my signature, rated and licensed for 11,500 pounds and a gooseneck trailer rated and licensed for 14,000 pounds with a gross combined weight of 25,500 pounds. If I am hauling anything that could be farm related, across state lines, I am engaging in interstate commerce and must comply with federal interstate commerce laws. In my case that would be paragraph B2, below. If I move farm equipment from one place to the other, it is interstate commerce, even if I am just going to use it at the other farm. If I cut hay on my property in Missery, bale it, load it on my trailer, haul it to my farm in Texas and feed it to my cattle, that is still interstate commerce. I must comply with the things outlined in paragraph B2 below. If I load some hay, or tools, or branding equipment in my truck alone, and drive across state lines, I am subject to interstate commerce rules, since my truck is licensed over 10,001 pounds.
I have a hobby of restoring old metal working machinery (Mills, Lathes, Shapers, etc. ). Since I do not do this for profit, or even to sell them, I do not have to comply with the interstate commerce rules. If I am hauling my own personal property, such as clothing, furniture, books, etc, I am not engaged in any commercial activity and do not need to comply with the interstate commerce rules. That does not mean that I won’t get pulled over and checked, but it does mean that I am not required, BY THE LAW, to comply.
A. Texas Intrastate
Within 150 air miles (172 statute miles) of farm – up to 48,000 pounds without class A license. Farm tagged trailers can only be used for ag purposes, as outlined in Tx law, within the 150 mile limit, as above. Farm tagged trucks are not limited to 150 miles, or ag. uses, but cannot be used to travel to a paying job. Hauling for hire, for any compensation is not farming.
B. Interstate
Crossing a state line, whether farming, or not, doing any sort of business activity, or anything that can be called “in the furtherance of a commercial enterprise”, immediately subjects you to the
Federal Motor Carrier Safety Administration rules. If you are hauling for your own business, they apply. If you are hauling for someone else’s business, they apply. If you are a farmer, some of them apply.
If you are hauling for your own, or someone else’s business, you must have a USDOT number, UCR registration, Operating Authority, possibly the fuel card, drivers Medical card, insurance of at least $750,000, Commercial Vehicle Inspection (DOT inspection) on the truck and trailer, fire extinguishers, triangles, log book for hours of service, Name and USDOT number on both sides of vehicle, etc.
If you are a farmer it is more confusing and depends on your gross combined vehicle weight. This only applies if you are hauling your own farm supplies and equipment. If you haul anything for hire, you no longer fall under these rules. If someone else is paying for the fuel, or buying lunch, or compensating you in any way, shape or form, you are For Hire and no longer farming.
1. Under 10,001 pounds GVW or GCVW. Nobody seems to care what you do. If you have a ½ ton truck and trailer, if you are under 10,001 pounds you do not seem to need to meet any commercial rules, unless you are hauling hazardous materials.
2. 10,001 to 26,000 pounds gross combined vehicle weight (GCVW). There are 3 ways they will check this. Licensed weight, Manufacturers rated weight, or actual weight. You must have a USDOT number and
Unified Carrier Registration (UCR). They don’t tell you this, but when you get the DOT number you must get the UCR. The DOT number is free, but the UCR is around $70, depending on how many vehicles you register with DOT. You do not need operating authority and, because of this and being under 26,001, you can use your regular liability insurance. The trucks and trailers that you will use must have a Commercial Vehicle Inspection (DOT Inspection). You must have fire extinguishers, warning triangles and your farm name and USDOT number on both sides of the power unit (Truck). The driver does NOT need a CDL, but must have the
Med Card, and logbook to show compliance with the
Hours of Service (HOS) as outlined in the FMCSA rules.
3. Over 26,000 pounds GCVW. All the above requirements apply with the addition of the following: Operating authority is required and with that goes the requirement for a minimum insurance of $750,000. Probable registration with the
International Fuel Tax Association (IFTA). The driver needs to have a class A CDL. Possible requirement for apportioned plates, but I am not sure.
This is, by no means, meant to be a comprehensive listing and guide to the federal regulations. I am merely trying to show the complexity and far reaching scope of the joys of complying with interstate travel, as experienced by one TDR member. I am certain that I have left something out, due to pure ignorance of the requirements. I am equally sure that there are those out there that will disagree with something I have written. Please keep in mind that these are the things that I have been told I must do, by professional law enforcement officers and FMCSA administrators, to be in compliance.
