Free Tennessee CDL Permit Practice Test: General Knowledge 2025

Truck drivers should find plenty of work in the great state of Tennessee because of its agriculture and manufacturing sectors and the state’s role as a major regional logistics hub. The largest manufacturing sector is automotive manufacturing. Hundreds of automotive suppliers are also represented. Other large manufacturing sectors are chemicals and food and drink production. FedEx is located here; its Memphis hub processes over 180,000 packages per day. One of the largest employment sectors is research and development, leveraging the Oak Ridge science complex. Numerous high-tech firms need truck drivers to deliver equipment and supplies to them. The Port of Memphis is the fifth largest inland port in the country, equipped for heavy intermodal transportation. Seaports, like airports, have secure areas. You’ll need a Transportation Worker Identification Credential (TWIC) card to pick up cargo there.

Tennessee is also the 11th most visited state in the country. Tourists flock to the Great Smoky Mountains National Park, the Tennessee River Valley, Elvis Presley’s birthplace in Memphis, and other points of interest, creating a demand for bus drivers.

Several highways support Tennessee’s role as a regional logistics hub: Interstate 40 starts in southern California, goes through Memphis, Nashville, and Knoxville, and then terminates in North Carolina. Interstate 65 runs from northern Indiana through Nashville and then south to Mobile, Alabama. Interstate 75 runs from northern Michigan at the Canadian border through Knoxville and Chattanooga and then south to suburban Miami, Florida.

To practice commercial driving under supervision, you must obtain a Commercial Learner’s Permit (CLP). You must meet several requirements, including passing an official knowledge test on commercial driving theory. You should read the official Tennessee Commercial Driver License Manual (Tennessee CDL Handbook 2025) because the official knowledge test is based on it. However, the manual isn’t that easy to learn from. Some aspiring drivers read the manual but failed the knowledge test anyway.
