Here's the fact that makes CDL prep simpler than it looks: federal rules require every state's CDL manual to follow the same national model, so the written knowledge tests are overwhelmingly the same from state to state — same test lengths, same 80% pass mark. States differ mainly in fees, scheduling, and a few state-specific rules. Train on the national banks in our trainer, and confirm the state-specific details in your official state CDL manual.
Eight states have full hub pages with per-state test facts: Texas, California, Florida, New York, Illinois, Georgia, Ohio, and North Carolina. Texas gets extra depth for one reason: its Section 14 Special Requirements test is a separate pass/fail exam that most prep sites barely cover — and we built a dedicated bank for it.
