Everything You Need to Pass Your CDL Exam Tests

BeginCDL is CDL test prep without the bloat: nothing to install, update, or change on your device, just log in securely and study.

We use the official CDL study guides for your state with our CDL test prep students, rebuilt so they can prepare section by section, on any device. The CDL practice tests use the full question bank for practice tests and CDL exam modes. The CDL practice test and CDL exam modes are designed to work with you at your pace. No filler lessons, no upsells, no subscription. Studying CDL classes and endorsements should be easy, not complicated. Let BeginCDL help you study for your career the right way.

Failing your CDL exam costs more than preparing.

CDL school costs thousands. Do not let the permit test hold you up. A failed CDL or endorsement test means paying for a retest, which is another trip to the testing site or school, and a later start on your new CDL career. Study it once, pass it the first time, and start your CDL career on schedule.

FAQ

Common CDL Questions

What CDL class do I need?

It depends on the vehicle weight rating, trailer weight, passenger use, school bus use, and whether hazardous materials are transported. The selector tool gives a starting point, and your state licensing agency makes the final determination.

Do I need ELDT before testing?

ELDT generally applies when you are getting a Class A CDL, Class B CDL, Class B-to-Class A upgrade, or a Passenger, School Bus, or HazMat endorsement for the first time.

Is HazMat ELDT different?

Yes. HazMat ELDT is theory training and must be completed before the hazardous materials knowledge test. The TSA security threat assessment is a separate requirement.

Can I study before buying training?

Yes. You can compare CDL classes, review endorsement topics, and use the selector tool first. Paid products add organized practice material, PDFs, audio, and training access.
