I have pretty specific taste preferences when it comes to tobacco. There are a fairly large number of blends that I do not care for.
A commercial driver license is a license issued in accordance with Federal Regulations that allows an individual to operate a commercial vehicle. Federal regulations require that an applicant be 18 years or older to apply for a commercial driver license (CDL) and be issued a commercial instruction permit.
Medical licensing may also hinge on completion of internships, fellowships, and residency. With that in mind, a learner's permit is permission to drive even though it comes with certain restrictions. It is still permission and therefore it is a license even though it is a limited license. Indeed, the same could be said with a regular drivers license.
