Missouri CDL Class A Practice Exam 2026

The Missouri Class A CDL practice test prepares you for the biggest rigs on the road, the combination tractor-trailers that haul freight across I-70 and I-44. This class A drivers license practice test and class A permit practice test share the same written general knowledge exam every applicant takes, so the questions here build the foundation for your Class A credential.

What are the three types of CDL license? Understanding the CDL classifications matters: a Class A covers combination vehicles rated over 26,001 pounds towing a trailer over 10,000 pounds, a Class B is a single vehicle over 26,001 pounds, and a Class C handles smaller vehicles carrying hazmat or 16-plus passengers. Those different types of CDL decide what you can legally drive.

The general knowledge test itself is 50 questions with an 80 percent passing score, meaning 40 correct, and it feeds every class. With Kansas City and St. Louis anchoring Missouri's long-haul freight network, keep the Missouri Commercial Driver License Manual handy and drill this Class A practice test until you are ready.
