No. To be exempt from CMV requirements and regulations, the vehicle must be registered as a recreational vehicle.
It is possible to obtain a CDL with diabetes, provided it's not too severe for you to be able to obtain a DOT medical card.
CDL stands for Commercial Drivers Licence. It's the licence you must hold to operate a CMV. CMV stands for Commercial Motor Vehicle, and is the vehicle itself.
You would need a commercial vehicle policy.
If you operate a vehicle requiring a CDL, if you operate a Commercial Motor Vehicle of 10,001 - 26,000 lbs. GVWR across state lanes, or if you operate a vehicle which would normally require a CDL, but is operated under an exemption (farm vehicles, emergency vehicles, RVs).
In certain states there are different qualifications for individuals to operate motor vehicles. Some things to take into consideration in answer this is the type of vehicle driven and what type of materials is being hauled.
It depends. If the lack of a defroster will make the vehicle unsafe, it puts the bus out of service.
It depends on the size and weight capacity of the fork lift in question. Also, unless you are speaking of a licensed and road-worthy vehicle which operate on the public streets, I do not believe that the light or heavy commercial status applies.
If you operate a commercial vehicle with a Gross Vehicle Weight Rating of more than 10,000 lbs., you're supposed to have the DOT Medical Card.
You could get licenced, but you can't operate a commercial vehicle while taking it.
If you don't have a CDL, you can't operate a commercial vehicle. You can't even so much as be in actual physical control of the vehicle (in the driver's seat with the motor running). Even if you possess a non-CDL Class A or B licence, this holds true - a non-CDL Class A/B only permits you to operate vehicles which fall under the exemptions for CDL requirements.
You can get a CDL at 18. However, you'd be restricted to operating a commercial vehicle in your home state. To operate a commercial vehicle interstate, and/or to get a hazardous materials endorsement, you must be 21.
