Sample practice questions
You should never use water on which fire?
Answer: Gasoline or electrical (Class B or C) — Water spreads liquid fires and conducts electricity; use a B:C or A:B:C extinguisher.
Which endorsement requires a TSA background check?
Answer: H (Hazardous Materials) — Only the Hazmat endorsement requires a federal TSA background check.
On a long downgrade, the correct braking method is:
Answer: Firm, brief snubs to ~5 mph below safe speed, then release to cool — Snub braking sheds less heat and prevents brake fade.

CDL licensing in Texas is administered by the Texas Department of Public Safety. Fees, scheduling, forms, and the official Texas CDL manual live on the official site: Texas DPS — official CDL page (verified 2026-08-09).
Truckcess is not affiliated with or endorsed by the Texas Department of Public Safety. Our practice tests cover the federal CDL knowledge standards (49 CFR Part 383) that every state exam is built on; exact question counts, fees, and procedures vary by state and change over time — the official site is always the authority.
How the Texas CDL process works
- Study the official Texas CDL manual from the Texas DPS — state exams draw from it.
- Pass the written knowledge tests to earn your Commercial Learner's Permit (CLP). You can take the CLP knowledge tests before completing ELDT.
- Complete Entry-Level Driver Training (ELDT) from a provider on the federal Training Provider Registry — required before your skills (driving) test. Truckcess provides the theory portion. (Exception: for the HazMat endorsement, ELDT theory is required before its knowledge test.)
- Pass the three-part skills test — vehicle inspection, basic control, and road driving.
The full prep course — every practice test, narrated lessons, the spoken pre-trip trainer — is one-time (Class A $69, Class B $59) with 12 months of access: mytruckcess.com/cdl.
