Written Practice Plus Hands-On Logic
Permit questions help with the written test. The free CDL games help you understand inspection and air-brake logic before you practice with a real truck — try the Build the Pre-Trip trainer or the Air Brake Control Room simulator.
The real Texas CDL General Knowledge test has 50 questions — you need 40 correct (80%) to pass. This practice test has 40 questions covering the same core topics to help you prepare.
This is a study tool, not an official Texas DPS exam. Questions are designed to help you learn — not replicate the exact DPS question bank.
As of June 1, 2026, the real Texas CDL and CLP knowledge tests are administered in English only, and interpreters are not permitted. These exams were previously offered in English and Spanish. Practicing here in English helps you prepare for the format you will see at Texas DPS.
