How much does it cost to get a cdl license in Tennessee?

Varies depending on what class CDL and what endorsements you wish to have, as well. A pricing guide is provided by the State of Tennessee (see related link). Note that the costs listed only cover the actual licencing fees, and do not cover the cost of driving school. Note also that you will first have to get a learner's permit for the appropriate class CDL you're testing for, unless you're transferring an existing CDL from another state. You will have to be a resident of Tennessee for 30 days before they will issue you a CDL, but the 30 day requirement does not apply to permits.
