About this test

Available in EN and ES

Your knowledge of safe commercial driving, covering right-of-way rules, railroad and highway crossings, braking and backing techniques, dealing with special road and weather conditions, and much more, will be tested to help you pass your CDL exam and become a safer driver. Each of the 50 questions has a hint, if you need it, as well as an explanation, which we recommend that you read so that you are able to more efficiently answer any question on the same topic that the real CDL exam might contain. Good luck with this practice exam, take it as many times as necessary to feel comfortable with the topics, and drive safely!

Enhance your preparation with our comprehensive General Knowledge test collection, tailored to cover all key topics of the CDL exam. For a complete understanding of the expenses involved, check out our guide on CDL license cost, and for a step-by-step guide to getting your CDL, visit our CDL license guide.
