CDL Practice Test for Texas Drivers: 2026 Study Guide and DMV Info

If you're getting your CDL in Texas, you're going through one of the highest-volume CDL programs in the country — Texas issues more commercial driver's licenses than any state except California. The good news: the written CDL exam in Texas is built on the same federal FMCSA framework as every other state, so the practice questions you study don't need to be Texas-specific to be effective. What IS Texas-specific is the scheduling, fees, and where you take the test — the Texas Department of Public Safety (DPS), not a separate DMV.

This guide gives you the federal practice content that prepares you for the Texas CDL written exam, plus everything Texas-specific you need to know to schedule and pass.

How the Texas CDL written exam works

The Texas DPS uses the standard FMCSA-aligned CDL knowledge tests. You'll need to pass:

• General Knowledge (50 questions, 80% to pass) — required for every CDL class
• Air Brakes (25 questions, 80% to pass) — required if your test vehicle has air brakes
• Combination Vehicles (20 questions, 80% to pass) — required for Class A
• Endorsements — separate written exams for HazMat (H), Tanker (N), Doubles/Triples (T), Passenger (P), School Bus (S)

The questions come from the Texas Commercial Motor Vehicle Drivers Handbook, which itself is the FMCSA model manual with minor Texas annotations. Practice questions modeled on the FMCSA framework will prepare you fully — there are no Texas trick questions.

Texas-specific things you need to know

Where to take the test: Texas DPS Driver License Offices. Find the nearest one at txdps.state.tx.us. The largest metros (Houston, Dallas, San Antonio, Austin, Fort Worth) have multiple CDL-capable offices, but appointment availability varies — it can take 2-6 weeks to get a slot in major metros.

ELDT requirement: Federal Entry-Level Driver Training (ELDT) is required nationwide before you can take a CDL skills test. Texas is fully integrated with the FMCSA Training Provider Registry. You must complete a course from a registered provider before scheduling your road test — written exams can be taken before ELDT is done, but the road test cannot.

CDL fees in Texas (2026):

• Initial Class A or Class B CDL: approximately $97 (covers the license + initial application)
• Each endorsement: approximately $11 each
• Skills test (taken at DPS or third-party tester): approximately $25 at DPS
• ELDT course (theory + behind-the-wheel): typically $3,000-$7,000 at private CDL schools

Fees are subject to change — always confirm the current rate at txdps.state.tx.us before your appointment.

Texas medical certificate requirement: All CDL holders must self-certify their type of driving (interstate, intrastate, excepted, non-excepted) and submit a current Medical Examiner's Certificate (DOT physical) to Texas DPS. Without it on file, your CDL can be downgraded to a regular license.

Free CDL practice questions for Texas drivers

These are sample questions written in the exact federal CDL framework Texas uses. Try them yourself — answers follow.

Question 1. What's the most important thing to remember about your stopping distance in a fully loaded combination vehicle?

A. It's the same as a passenger car at any speed
B. It can be more than 300 feet at 55 mph — longer than a football field
C. Air brakes mean you can stop in half the distance of a regular truck
D. Stopping distance only matters in wet weather

Question 2. When the road is wet but not flooded, you should reduce your speed by about:

A. One-third
B. One-half
C. Three-quarters
D. Speed doesn't need to change

Question 3. What's the minimum tread depth for steering tires on a CDL vehicle?

A. 1/32 inch
B. 2/32 inch
C. 4/32 inch
D. 6/32 inch

Answers

1. B — Total stopping distance for a loaded tractor-trailer at 55 mph on dry pavement is roughly 290-330 feet (perception + reaction + brake lag + braking distance). This is foundational test material. 2. A — One-third on wet roads. Half if conditions are packed snow. 3. C — 4/32 inch on steering tires; 2/32 on all other tires.

How long does it take to get a CDL in Texas?

A realistic timeline for most Texas applicants:

• Week 1-3: Study for the written exams using federal-aligned practice questions and the eBook.
• Week 4: Take the written exams at a Texas DPS office. Get your Commercial Learner's Permit (CLP).
• Week 4-8: Complete ELDT (theory + behind-the-wheel) at a registered provider. You can drive on public roads with a CDL holder once you have the CLP.
• Week 8-10: Schedule and take your skills test at DPS or a third-party tester.
• Total: 6-10 weeks for most full-time students; 8-16 weeks for part-time learners.

Texas CDL FAQ

Can I take all my Texas CDL written tests in one DPS visit? Yes, in most cases. Bring your application, ID, proof of residency, and Social Security card. Plan for a 2-4 hour visit if you're testing for multiple endorsements.

How many times can I retake the Texas CDL written exam? Generally 3 attempts per visit, with a re-test fee. After the third failure, most offices require a waiting period before reapplying.

Does Texas accept out-of-state CDL training? Yes — ELDT credit transfers nationwide via the FMCSA Training Provider Registry. If you completed ELDT in another state, your training is valid in Texas.

Good luck with your Texas CDL. With consistent prep using federal-CDL practice questions, most applicants pass on the first try.

Where to take your Texas CDL test

Texas DPS administers CDL written and skills tests at Driver License Mega Centers and select regional offices across the state. The biggest CDL testing locations:

• Houston area: Rosenberg Mega Center, North Houston Mega Center, Pasadena, Spring (NE Houston)
• Dallas–Fort Worth: Garland Mega Center, Carrollton, Fort Worth, Lake Worth, Hurst
• San Antonio area: Leon Valley Mega Center, San Antonio Babcock, Universal City
• Austin area: Pflugerville Mega Center, Austin North Lamar, Round Rock
• El Paso: Hondo Pass, Northeast El Paso
• Lubbock, Midland-Odessa, Tyler, Beaumont, McAllen, Corpus Christi, Amarillo: regional offices

Mega Centers are designed specifically for high-volume testing and tend to have shorter waits than smaller offices. Schedule appointments at txdpsscheduler.com as early as possible — popular Mega Centers often book out 2-4 weeks during peak hiring seasons (March–June, August–October).

Texas CDL fees (2026)

Fees were last updated by Texas DPS in late 2025 and are accurate for 2026. Confirm current fees at the time of your visit at dps.texas.gov.

Texas-specific retake rules

If you fail any portion of the Texas CDL written exam, you can retake it the same day at most Mega Centers (subject to scheduling availability and the $25 retake fee). After three failed attempts on the same test, most DPS offices require a 30-day waiting period before you can reapply.

If you fail the skills test, retakes typically require a new appointment. Skills test slots fill up faster than written-test slots, so don't wait — schedule your retake immediately after a failure.

What separates Texas from other state CDL processes

A few practical differences worth knowing:

• Texas requires a Department of State Health Services (DSHS) medical examiner certificate to be uploaded to the FMCSA National Registry, then submitted to Texas DPS. The certificate must be from a Certified Medical Examiner listed on the FMCSA registry.
• Texas accepts the federal Single Tire Vehicle restriction: if you take your skills test in a vehicle with single rear tires (not duals), you'll have a restriction prohibiting you from driving vehicles with duals.
• Air Brakes restriction: same as federal — if you take your skills test in a vehicle without air brakes, you cannot drive air-brake-equipped vehicles.
• Texas residency proof: requires two documents (utility bill, lease, mortgage statement, etc.) from different sources, dated within the last 90 days.
• Spanish-language testing: Texas DPS offers the CDL written exam in Spanish for in-state drivers (federal HazMat must still be taken in English per TSA rules).

Final word for Texas applicants

Texas has the largest CDL workforce in the U.S. — over 350,000 active CDL holders — and a corresponding network of testing locations and CDL training schools. The federal exam content is identical to what drivers face in any other state, so practice with high-quality federal-CDL questions and you'll be well-prepared for whatever the Texas DPS examiner throws at you.

The state's main quirks are administrative (fees, residency proof, scheduling at Mega Centers) rather than test-content related. Get those squared away ahead of time and the test itself becomes the easy part.
