You could teach classes pertaining to the written tests, but you couldn't teach the on-road portion or any other portion of the training which involved actually operating the vehicle. CDL students on a permit must be supervised by a fully licensed CDL driver, and you can't even be in actual physical control of a CMV without a CDL.
Yes, you would. Without the trailer, you could operate it with either a Class A or Class B CDL.
Depends. You can drive up to a Class 6 truck (up to 26,000 lbs. GVWR) without a CDL. Class 7 or Class 8 trucks require 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.
It can be done.
If you are aware of the laws and have had practice, you can always try to get your CDL without taking a class. It's definitely not recommended though and would be better to help you pass it the first time by taking the class.
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.
When I had my own business, they needed a Class A CDL and hazmat endorsement.
Class 3 truck with a rollback body? No, it doesn't require a CDL.
Yes.
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.
Yes, you can obtain a CDL Class A license without first having a Class C license. The Class A CDL allows you to drive a combination of vehicles with a gross combination weight rating (GCWR) of 26,001 pounds or more, including trailers. However, it’s important to meet the specific requirements of your state, as regulations can vary. Generally, you'll need to pass written and driving tests to secure your CDL.
