CDL Practice Test Overview
We've provided instructions to Get Your CDL Program job seekers so that you understand how the program works. Becoming a professional over-the-road truck driver requires getting your commercial drivers license (CDL). To obtain your CDL, you'll need to first get your commercial learners permit (CLP), and to do that, you'll need to pass three written tests at your local drivers' licensing office.
Use the free CDL practice tests on this page to check your knowledge and prepare for your written CDL exams. There are two types of commercial drivers license practice tests on our site.
The first set of commercial practice test has feedback, including explanations for the anwers. You can think of this practice CDL test as a CDL study guide.
The second group of CDL practice tests simulates taking the written CDL exam - no feedback, just the the questions and answers. You can check your knowledge and see if you are ready to get your CLP and CDL.
There are three different tests.
When you go to the driver licensing center, you must take and pass those three tests to get your CLP, so use these written sample tests as well as the resources from your state (including state-specific dmv cdl practice tests) and our site to prepare yourself!
Remember, these free tests are provided as a supplemental resource. You can also use the CDL Manual as a CDL study guide.
