What Is CDL Class A Theory Training?

Understanding the Basics

CDL Class A theory covers all the essential knowledge needed before you begin hands-on behind-the-wheel training. It focuses on preparing drivers to safely and legally operate heavy commercial vehicles like tractor-trailers.

At Get Drivers Ed, our CDL Class A theory course dives into:
