Texas CDL Test Questions 2026: Test Order and Study Guide
Texas CDL knowledge-test guide for 2026: mandatory test order, English-only testing, class and endorsement topics, and how to study from the official handbook.
Texas CDL knowledge testing is best understood by sequence rather than by memorizing unofficial question counts. DPS publishes the order in which the knowledge exams must be taken, and that order determines which test you face first and when the process can continue.
Texas Requires a Specific Test Order
- Texas Commercial Rules.
- General Knowledge.
- Combination Vehicles for Class A applicants.
- Air Brakes when applicable.
- Endorsement examinations.
Prepare for the tests you actually need for your intended class, brake system, and endorsements. Do not spend equal time on every handbook section if a section does not apply to your credential.
English-Only Testing
Effective June 1, 2026, all Texas CDL and CLP knowledge examinations are administered in English only. Spanish-language CDL knowledge testing was discontinued, and interpreters are prohibited. The skills test is also conducted in English.
Texas Commercial Rules
Texas places its state commercial-rules exam first. Study Texas-specific commercial licensing and operating rules rather than assuming the federal general-knowledge material alone is enough.
General Knowledge
General Knowledge covers the core concepts every commercial driver needs: inspections, basic vehicle control, safe operation, communication, speed and space management, hazards, emergencies, and cargo-related safety.
Combination and Air Brakes
Class A applicants must prepare for combination-vehicle operation, including coupling, trailer behavior, inspections, rollover and jackknife prevention, and safe control. Applicants who want to operate full air-brake vehicles should master the air-brake section so they do not create an avoidable restriction.
Endorsements
Additional examinations apply to endorsements such as Tank, Doubles/Triples, Passenger, School Bus, and Hazardous Materials. HazMat also carries federal training and security requirements beyond the DPS knowledge exam.
Do Not Treat Unofficial Question Counts as State Guarantees
Practice sites often publish fixed question counts and exact item predictions. Texas DPS's current application page is more useful because it publishes the required test sequence and official handbook. Use practice questions to measure understanding, but use the DPS handbook as the authority.
