CDL Practice Tests
There’s more to earning a Commercial Drivers License than just driving–you’ll first have to get a Commercial Learner’s Permit. You’ll also need to pass a General Knowledge test. The sooner you pass these written tests, the sooner you’ll be on the road earning money, so be as prepared as possible from the start.
To help you succeed, we’ve created CDL practice tests that mimic current DMV tests in both content and format. The subjects needed–General Knowledge, Air Brakes, Combination Vehicles–are all available.
Best of all, these CDL practice tests are free and you can take them as often as you like so you can feel confident when you take the official DMV tests. To get started, study your CDL Manual and then choose from any of our free CDL practice tests, listed below.
The practice quizzes are designed to give you a sampling of what to expect on the Commercial Learner's Permit (CLP) tests. Each quiz randomly presents 15-20 questions from a larger pool of questions, providing a different set of questions each time you take a quiz. Questions vary from quiz to quiz as well. Correct and incorrect answers are shown instantly. To review answers and learn more from the explanations provided for some of the questions, use the "Back" button before reaching the end of the quiz.
