Kenny,
It is too cold outside to go out and finish spreading and smoothing gravel I have had delivered or delivered myself to rebuild winter damaged driveways so I'm bored and browsing websites.
I had a question about converting my own TX CDL A license to a TX Class A operator license since I won't be hauling commercially again and found an old website I had saved years ago that lists the requirements for driving or towing large and heavy recreational vehicles in the various states.
RV Driver's License Requirements
While scanning down the list to find TX I ran across the facts for NY state.
I was surprised to realize that you were posting incorrect information about your own state of NY as well as SC and federal. NY does not require a CDL for vehicles under 26k as you claimed.
According to NY's own driver license website NY rules are identical to US DOT for CDL. Here is the link to NY Class D OPERATOR's LICENSE:
NYS DMV - Driver's Manual - Chapter 1
I see now why you argued so stubbornly about things I knew to be incorrect. Just because a vehicle is defined as a commercial vehicle does NOT mean the driver must have a CDL.
You are confused about the distinction between a commercial vehicle which can be a vehicle over 10,000 lbs. used for business but the need for a commercial (CDL) driver license only begins when the single or combined weight exceeds 26,000 lbs.
