Before you get a CDL, you will. You cannot legally operate any vehicle requiring a CDL on a public roadway without either holding the appropriate class of CDL (plus endorsement when necessary) or the appropriate class of CDL permit while being supervised by a licensed CDL holder.
When you get a CDL permit, you still retain your regular driver's licence. So, if your state's standard drivers licence is Class D, and you got a Class A permit, it would read something like "DPA" - it would still function as a Class D licence, and you'd still be able to drive your own personal vehicle on your own, but you would only be permitted to operate a commercial vehicle while being supervised by a fully licenced driver.
You do it while you're being supervised by a fully licenced driver.
Your CDL permit is in addition to the class of licence you had beforehand. So long as you were licenced to drive a car before you got your CDL permit, you can drive your own car while you possess a CDL permit.
In order to obtain a CDL permit, you have to pass a driving test and get your license. When you get your license for a CDL permit, then you will be ble to drive trailer trucks and/or buses whenever you want to.
Yes.
It's illegal to drive alone on a learner's permit at any age in any state. The only exception to this is for persons who have a CDL learner's permit - since they must already possess a regular license prior to getting a CDL, the CDL learner's permit serves as a regular license and a learner's permit for CMVs.
You can drive commercial vehicles while supervised by a fully licenced driver.
yesAdded: Use caution and check with the DMV's of the states into which you wish to drive. NOT ALL states honor out-of-state drivers permits.
Yes
What type of permit? A CDL permit is, yes. A regular learner's permit is not. As with a full CDL, you're required to maintain a current DOT medical card with a CDL permit.
No... to drive a bus unsupervised, you need an unrestricted, full-on CDL license, with a passenger endorsement. You may not legally operate a bus - loaded or empty - otherwise.
To drive a cement truck legally, you need a class B CDL (Commercial Drivers License). At 18, you can apply for a class B CDL.
Not by yourself. You MUST have a fully licensed driver with you at all times while operating a CMV on a permit.
Yes, and they must be in the seat beside you.
