I know this is an old thread but I will like to add my two cents. I'm a retired as Special Agent for the U.S Department of Transportation. Weight stations are designed to weight commercial vehicles to make sure that those vehicles meet the weight restriction. Every state has their own definition of weight restrictions in their highways, but with that said the key word in here is COMMERCIAL. The Federal Motor Carrier Safety Regulation (FMCSR), have two definitions as to what is a commercial vehicle.
The first definition is on 49 CFR Part 390.5 and it read as follow:
Commercial motor vehicle means any self-propelled or towed motor vehicle used on a highway in interstate commerce to transport passengers or property when the vehicle— (1) Has a gross vehicle weight rating or gross combination weight rating, or gross vehicle weight or gross combination weight, of 4,536 kg (10,001 pounds) or more, whichever is greater; or(2) Is designed or used to transport more than 8 passengers (including the driver) for compensation; or(3) Is designed or used to transport more than 15 passengers, including the driver, and is not used to transport passengers for compensation; or(4) Is used in transporting material found by the Secretary of Transportation to be hazardous under 49 U.S.C. 5103 and transported in a quantity requiring placarding under regulations prescribed by the Secretary under 49 CFR, subtitle B, chapter I, subchapter C.
Also 49 CFR 390.3(f) clearly state that “Unless otherwise specifically provided, the rules in this subchapter do not apply to— (3) the occasional transportation of personal property by individuals not for compensation nor in the furtherance of a commercial enterprise.
So there you have it. If you are just RVing or driving a truck for your own pleasure the regulations are not applicable to you.
The other definition is regarding CDL license. While CDL licenses in the U.S. are issued by the each individual state, every state has to abide by the federal definition in 49 CFR Part 383.
49 CFR 383.3(a) (a) state as follows: The rules in this part apply to every person who operates a commercial motor vehicle (CMV) in interstate, foreign, or intrastate commerce, to all employers of such persons, and to all States.
So as you can see if there is not commerce, the regulations are not applicable to you:
Examples 1: John drives a 36,000 lbs RV for his pleasure from Alaska to Wyoming. He is not engaging in any commerce whatsoever. The regulations do not apply to him.
Example 2: Jane drives a 36,000 lbs RV to take it from the factory in Ohio to the dealership in Florida. She gets paid to do this. Because she is charging to do the work, the regulations are fully applicable to her including the CDL requirements. She would need a Class B CDL license.
Example 3: Martha drive tractor with a trailer to carry her horses to a show. (GVWR of the tractor 30,000 LBS with a trailer with a GVWR of 14,000 LBS) She doesn't get any money or prizes to do so. Also she doesn't have any sponsors. She does this for pure pleasure. Once again no commerce not regulated.
Example 4: Stephen drives a tractor with a trailer to carry his horses. (GVWR of the tractor 30,000 LBS with trailer with a GVWR of 14,000 LBS) He doesn't actually get any money to do so. But he competes and he may win a prize of $500, if he comes on first place. Also he has a sponsor that provides feed for his horses in exchange for him to put their name on his trailer. The DOT don't care whether you win the prizes or not, but to the DOT the fact that you may make some money is enough to prove commerce in this case, additionally because he actually advertise for the feed company in exchange for the feed for his horses, the monetary value of the feed is considered a factor in determining his compliance with the regulation. Also because the combination of the tractor and trailer is over 26,000 LBS with a trailer over 10,000 lbs, he will need a Class A CDL license. :1888fbbd:
