QUESTIONS

Before you buy.

Why is this cheaper-shorter than full Class A?

The FMCSA lets current Class B holders take a reduced upgrade curriculum - you already proved the shared material. This course is only the Class A additions.

Do I need to retake what I know?

No. That is the point of the upgrade path.

Do I have to redo all of Class A theory?

No. The FMCSA created a separate, shorter upgrade curriculum for Class B holders. That is what this course is.

I had a Class B before 2022. Do I still need this?

Yes. Class A is a new class of license, and ELDT applies to the upgrade regardless of when you got the Class B.

What else do I need?

A Class A learner permit (combination vehicles knowledge test), behind-the-wheel training in a tractor-trailer, and the Class A skills test.

What if I am not satisfied?

Full refund within 7 days if you have completed less than 10% of the course and taken no quizzes. Bought the wrong course? We swap it free. A course already filed with the FMCSA registry cannot be refunded.
