All you'd ever need to know about becoming a teacher for CDL certification can be found at www.ctc.ca.gov/credentials/teach.html. In addition, make sure to check out private companies that can help you become certified to teach.
There is no such thing as a cdl training that pays you. You will have to pay them for a cdl training. Unless of course you will be teaching the class, then you will get paid.
Each state is going to have different CDL requirements. I would recommend checking with your local Department of Motor Vehicles for your state requirements.
The D.O.T. website has a section devoted entirely to Commercial Driver's License requirements. You can see it all here: http://www.fmcsa.dot.gov/registration-licensing/cdl/cdl.htm
There are different requirements for each state. I would recommend contacting your local department of motor vehicles for the requirements specific to your state.
The requirements pertaining to all classes of CDL (A, B, and C) are established by federal guidelines. However, the licences themselves are state issued.
No. U-Haul doesn't rent out trucks higher than Class 6, which have a GVWR under the weight requirements for a CDL.
Not sure what you mean, exactly. Class A is considered the "higher" classification, yes. If you have a Class A CDL, you can operate vehicles requiring that class of licence or any class below that. You could operate a vehicle requiring a Class B CDL, for example, but a driver with a Class B CDL wouldn't be permitted to operate a combination requiring a Class A CDL.
Depending on your state, there may not be any non-CDL Class A, B, and C licenses - CDLs are federally regulated... other license types are not. In states which do have that system, the weight rating equivalents are the same as they are for the corresponding class of CDL.
No. Motor homes are exempted from CDL requirements (for better or worse). Some states, however, may require residents to obtain a non-commercial equivalent licence (Class A or B) for non-commercial vehicles matching the weight requirements for the equivalent CDL licence.
Firefighting and emergency response vehicles are exempt from CDL requirements under federal law. The state may, however, require that a non-CDL Class A or B licence be held by the driver of the vehicle, and individual department policies may require a CDL, rather than a non-CDL licence.
CDL classes are A, B, and C - there is no Class D CDL.
Depends on which Class of CDL. A driver with a Class C CDL is not licensed on that vehicle. A driver with a Class B CDL can drive that combination only if the GVW of the trailer is less than 10,000 lbs. A driver with a Class A CDL can drive it.
