Texas CDL General Knowledge Practice Test 1: what to expect and what trips drivers up

This is the flagship Texas CDL practice test, and it is the right place to begin. Our free CDL practice test mirrors the structure of the real 2026 Texas CDL general knowledge exam, so treat it as your first honest scorecard. How many questions are on the Texas CDL general knowledge test? There are 50, and passing requires 80 percent, which means 40 correct answers. That standard comes from federal FMCSA rules, so it is identical in El Paso and in Texarkana.

The same exam earns your Commercial Learner's Permit, so anyone searching for the Texas CDL permit test is already in the right place: studying for your CLP and studying general knowledge are one job, not two. Where you intend to run shapes what comes next, whether that is Permian Basin oil and gas work, container and petrochemical freight through the Port of Houston, long-haul running on the I-35 corridor, or cattle and agricultural loads across the Panhandle.

Use this DMV CDL practice test online alongside the Texas CDL Manual, and repeat it until wrong answers become rare rather than random.

Keep going:

Every question traces back to the Texas CDL Manual - skim the right-of-way and signs chapters before your retake.
