Anything whose purpose is commercial in nature would be a commercial vehicle. To that end, rental cars are commercial vehicles. If you're talking about the FMCSA definition of a Commercial Motor Vehicle, it would depend on year, make, model, and if it's used on a for-hire basis. If it's used for commercial purposes and has a Gross Vehicle Weight Rating in excess of 10,000 lbs., it's a Commercial Motor Vehicle, and, IIRC, the current models of the Ford F350 and other one ton chassis have a Gross Vehicle Weight Rating in the 12 - 13,000 lb, range, meaning they would be CMVs, and they would require the FHWA annual inspection sticker, etc. The operator would also be required to keep a current DOT medical card in interstate operations.
Yes,to drive a one ton dump truck a commercial driver's license is required;
To answer that question I believe because of the gross vehicle weght the half/ton would not be considered a commercial vehicle, but however check with your local DMV.
Depends on make, mode, and configuration. A commercial truck is simply a truck used for commercial purposes... for the purposes of meeting the FMCSR criteria to be defined as a Commercial Motor Vehicle (CMV), it simpy has to be a vehicle used for commercial purposes which has a Gross Vehicle Weight Rating in excess of 10,000 lbs, which a one-ton pickup does exceed.
No.
That depends on what type of transmission the dump truck has. A dump truck could be anything from a one ton pickup to a Class 8 truck, all the way up to the articulated dump trucks used for sitework and the off-road dump trucks used in rock quarries and such.
A dump truck can be as small as a one ton pickup or as large as Caterpillar 797F, which is capable of hauling 400 short tons.
Alternator would have to be tightened if it is an older vehicle that allows you to do so.
Somewhere in the vicinity of one ton.
12 ton
You would have to go to the DMV in your state and apply for a CDL license. However, in order to get a license to drive a dump truck, you first have to take and pass a course for commercial trucking.
Commercial trucks with a Gross Vehicle Weight Rating of 10,001 lbs. or more. So, basically, a one ton pickup and larger, when used for commercial purposes.
about 5 ton depending on how much the truck weighs and what the truck is plated for in your state
