You get unlimited attempts and nonstop access to train whenever your schedule allows, adding flexibility to your learning journey. A minimum score of 80% is required to pass this practice test.
As you begin your first training session, you can use the test settings menu to customize your testing experience.

You can also use the language switcher and increase the font size by adjusting the slider. Every question includes a detailed explanation, which is revealed after you select an answer. This immediate feedback can help you learn from your mistakes shortly after they occur. For future reference, we recommend noting this feedback in a notebook or notebook app.

The pre-trip inspection involves a walk-around procedure, which you should perform the same way every time to make it easier to remember. The National CDL Manual (Iowa CDL Handbook 2026) is an official resource published by the Department of Transportation (DOT). You should read its contents several times during your learning phase, focusing especially on Section 11 (Vehicle Inspection). You can open this resource in another window while you train with this practice test. Although this approach will not be allowed on exam day, doing it now will allow you to learn more effectively.
Keep track of your scores and watch your performance improve as you become more familiar with the pre-trip inspection. Once you consistently obtain passing scores on this practice test, you can move on to our other tests. Check out our Free Iowa CDL Permit Practice Test. When used regularly, this tool can make the difference between failing and passing the official General Knowledge Exam.
