Common Texas questions
- Which Texas CDL package should I buy?
- Match it to the vehicle: Class A for tractor-trailers, Class B for straight trucks and buses, Class C with Passenger for vans and small buses. Add HazMat + Tank for fuel and chemicals and School Bus for district work. The Complete package covers all of it if you are undecided. The free Texas CDL Selector asks a few questions and picks for you.
- Are these practice tests valid for the Texas CDL exam?
- Yes. CDL knowledge tests follow the federal standard in 49 CFR 383, so the material applies in Texas. Tests are administered by Texas Department of Public Safety; each product page lists the Texas specifics for that test.
- How long do I have access?
- 120 days from purchase for each product, with unlimited practice tests during that time. Most Texas applicants pass well inside that window, and a retake at Texas Department of Public Safety is still covered if needed.
