Free New Jersey CDL Combination Practice Test 2025

Here is a free New Jersey CDL Combination practice test! This practice test, one of several we offer, will help you prepare to pass the official Commercial Driver’s License (CDL) Combination Vehicles knowledge test. You must pass this knowledge test to operate combination vehicles, such as semi-trucks and tractor-trailers.

We’re sure that you were advised to study Section 6 (Combination Vehicles) of the official New Jersey Commercial Driver License Manual (New Jersey CDL Handbook 2025) to get ready for the Combination Vehicles knowledge test. This study guide contains all the material on which you’ll be tested. Now that you’ve read it, do you think you can pass the official Combination Vehicles knowledge test? If you feel you could use more help to pass it – well, that’s what we’re here for.

Answering the questions on this Combination practice test will help reinforce what you read in the CDL manual and make the material easier to remember. The practice test is based on the official state CDL manual, just like the official knowledge test. It is up to date as of March, 2025. There are 30 multiple-choice questions and answers to assess your understanding of such topics as combination braking systems, combination driving techniques, coupling, and pre-trip inspections. However, this practice test differs from the official knowledge test in its extra features to help you learn, including a hint and an explanation of the correct answer for each question, and an automated assistant for even more help.

Once you’ve passed all your required tests and have your Class A CDL in hand, you’ll be able to explore all the economic opportunities open to tractor-trailer and semi-truck drivers in New Jersey. The state’s proximity to New York City and Philadelphia, its warehousing and distribution centers, and its seaports create a high demand for truckers. Amazon, Walmart, and Target all have large distribution centers in New Jersey. Port Newark–Elizabeth Marine Terminal is the main container ship port for containerized cargo entering the New York metropolitan area and the northeast United States generally. Truckers pick up containers there for transport to various distribution centers. Finally, the state is home to numerous chemical, pharmaceutical, and refinery industries, all of which employ truckers to deliver equipment and supplies to them and transport their products. (A Hazardous Materials endorsement might come in handy here. Want to pass that official knowledge test? We have Hazardous Materials practice tests too.)

Interstate 95 (known in the state as the New Jersey Turnpike) is the most important north-south truck route on the Eastern Seaboard. Other important truck routes include Interstates 78 (east-west), 80 (east-west), and 295 (north-south); and U.S. 1/U.S. 9 (north-south).
