Getting Your CDL in Texas
To get a Commercial Driver License in Texas, start by studying the Texas Commercial Motor Vehicle Driver Handbook. The manual explains which sections match the knowledge tests, endorsements, restrictions, vehicle inspection test, basic control test, and road test.
Texas CDL Permit Test Focus Areas
Texas applicants should study the General Knowledge material first, then add sections for the vehicle they plan to drive. Air Brakes, Combination Vehicles, Passenger, School Bus, Hazmat, Tank Vehicles, and Doubles/Triples each require focused study when they apply.
The Texas CDL skills test also includes vehicle inspection, basic control, and road driving. That is why this page includes state-focused permit questions and links to pre-trip inspection practice.
Common Questions about the Texas CDL
Do I need to take all the tests?
No. The General Knowledge test is required for everyone. Other tests depend on the vehicle you plan to drive (e.g., Air Brakes if your truck has them, Combination if you drive a tractor-trailer).
How to Prepare
- Read the official Texas Commercial Motor Vehicle Driver Handbook manual carefully.
