Already convinced? Get it now!Upgrade to CDL Premium
CDL training schools may offer as little as one week of preparation for the knowledge test. There is so much to learn that you may not be ready to pass it in so short a time. CDL Premium provides a highly affordable way to fully prepare for the knowledge test and all endorsement exams. With your Commercial Learner Permit in hand, you may only have to purchase behind-the-wheel driving instruction or a refresher course from a regular CDL training school rather than spend thousands of dollars on a full course.

Customers agree: our questions are nearly identical to the real exam.
