I doubt it for just a purchase.
No you do not need a CDL for this. You will need to have a license plate and registration for the trailer along with opperating tail and brake lights.
Anything defined as a CMV will require a CDL, regardless. So if it's pulling a trailer, yes, it will require a CDL.
Yes, you would. Without the trailer, you could operate it with either a Class A or Class B CDL.
Depends on the GVW of the trailer and the Gross Combined Weight Rating of the truck and trailer.
If the total weight rating of the combination (power and trailer) is over 26,000 lbs., and it's not a vehicle under exemption for CDL requirements, then yes.
If the Gross Combined Weight Rating (Weight Rating of Truck + Weight Rating of Trailer) come out to 26,0001 lbs. or higher, then yes - you would need a Class A CDL.
no only if you are a cdl licensed driver hauling product to be sold
IF it is for commercial/business purposes and IFthe trailer and tow vehicle come up to a Gross Combination Weight Rating in excess of 26,000 lbs., then yes, you need a Class A CDL.
Not necessarily, but specifics matter in regard to this question.
If the Gross Vehicle Weight Rating of the trailer doesn't bring the Gross Combined Weight Rating of the entire combination in excess of 26,000 lbs, you don't need a CDL for it.
That depends. CDL requirements depend on the weight rating of the vehicle, not the weight it actually is. If you need a CDL for it when it's loaded, then you need a CDL for it when it's empty. If it's a single vehicle or a combination rated at more than 26,000 lbs, and in which the vehicle in tow is rated at 10,000 lbs. or less, then you need a Class B CDL. If the trailer is rated at more than 10,000 lbs., and the total Gross Combination Weight Rating is more than 26,000 lbs., then you need a CDL.
Yes. In most cases you will need a CDL Class B license because of the weight of the truck. However, if you would be driving a semi with a dump trailer, you would need a CDL Class A license.
