Free Tennessee CDL Combination Practice Test 2025

  • Perfect for first-time and renewal CDL/CLP applicants, and those adding endorsements.

Drivers of combination vehicles, such as semi-trucks and tractor-trailers, should find plenty of job opportunities in the great state of Tennessee. Good opportunities should exist in the state’s agriculture and manufacturing sectors and in the state’s role as a major regional logistics hub. Tennessee’s agriculture sector has a rather steady demand for truckers to transport products like grains, cotton, tobacco, and lumber. The state is home to several large automotive manufacturers as well as hundreds of automotive suppliers. Other large manufacturing sectors are chemicals and food and drink production. 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 FedEx World Hub is located in Memphis, where it processes over 180,000 packages per day. The Port of Memphis is the fifth largest inland port in the country, equipped for heavy intermodal transportation. Truckers experienced in logistics and intermodal transportation may be able to take advantage.

Highways that support Tennessee’s role as a major logistics and intermodal hub include Interstates 40, 55, 65, 69, and 75.

To obtain a Commercial Driver’s License (CDL), you must pass a medical examination, an official knowledge exam on general commercial driving theory, and a three-part skills test. To be allowed to drive combination vehicles, you must also pass an official Combination Vehicles knowledge test on the theory of operating combination vehicles.

You’ve probably been reading the official Tennessee Commercial Driver License Manual (Tennessee CDL Handbook 2025) because the Combination Vehicles knowledge test is based on it. But maybe you doubt that’s enough? Maybe you’d like some additional help to be sure you pass that test. Great! We can help, just as we’ve already helped thousands of other aspiring drivers.

This free Tennessee CDL Combination practice test is based on the official state manual, just like the official knowledge test. It’s up to date as of November 2025. There are 25 multiple-choice questions and answers on such topics as combination braking systems, combination driving techniques, coupling and uncoupling, and pre-trip inspections. Unlike the official knowledge test, this practice test comes with our automated assistant, which can help you out on a question by giving you a hint and an explanation of the correct answer. What this practice test doesn’t have is a time limit. Take your time to improve your chances of passing the test while learning as much as you can from the experience.
