Texas CDL Written Test — Questions, Cost & Study Tips (2026)

Studying for your Texas CDL written exam? Here is what applicants typically need to know before visiting Texas DPS.

How many questions on the Texas CDL test?

Texas general knowledge written exams commonly include about 50 multiple-choice questions for the core CDL knowledge test. Endorsements such as air brakes, combination vehicles, hazmat, and passenger are separate written tests if your license class requires them.

PassCDL mirrors this structure: start with general knowledge, then add endorsement practice for the tests you need.

Texas CDL test cost (approximate)

Written exam fees at Texas DPS are typically $25–$40 per attempt (varies by office and endorsement). Failing and retesting can cost more than a month of PassCDL Pro — many students prefer unlimited practice before test day.
