Texas CDL General Knowledge Practice Exam 2026

The Texas CDL general knowledge test is the exam standing between you and a commercial career, and this simulator reproduces it end to end. Wondering about the count before you sit down? The commercial drivers license test contains 50 questions and demands 80 percent to pass, so 40 correct answers clear it and 11 misses do not. That threshold is set federally, not by Texas, which is why the CDL knowledge test looks the same in every state.

This full-length CDL exam simulation draws from the entire 2026 subject pool without labeling topics, so you get the same unpredictable sequencing the real test uses. Vehicle inspection, control systems, cargo, space and speed management, hazard perception, emergency response, and driver fitness all appear.

Passing this exam is also how you obtain your Commercial Learner's Permit, which is the legal step before any skills testing. Keep the Texas CDL Manual beside you between attempts, and only book with Texas DPS once this simulator stops surprising you.
