You’re planning to get your Commercial Driver’s License in Texas — and you picked the right state to do it. Texas leads the nation in trucking employment with over 200,000 commercial truck drivers on the road, moving freight worth billions of dollars every year through 3,240 miles of interstate highway. The trucking industry in Texas generates more revenue than in any other state, and the demand for qualified CDL holders keeps growing.
But before you can join the workforce driving an 80,000-pound combination vehicle through Dallas, Houston, or the long stretches of I-10 through West Texas, you need to pass the Texas CDL exam. The Texas Department of Public Safety (DPS) administers the CDL program under federal FMCSA guidelines, and the process is rigorous by design — because the stakes on the road are real.
This guide gives you everything you need to prepare for the Texas CDL test: exact test format, Texas-specific requirements, what’s different from other states, and free practice tests covering every knowledge exam you’ll face.

Texas CDL Requirements: What You Need to Know
Texas follows the federal CDL standards established by the FMCSA under 49 CFR Part 383, with some state-specific requirements administered by the Texas Department of Public Safety (DPS). Here’s exactly what Texas requires:
Age Requirements in Texas
| License Type | Minimum Age | Restrictions |
|---|---|---|
| Intrastate (Texas only) | 18 years | Cannot drive across state lines |
| Interstate (all states) | 21 years | No state-line restrictions |
| HazMat Endorsement | 21 years | Federal requirement — no exceptions |
Texas CDL Fees
| Fee Type | Amount | Details |
|---|---|---|
| CLP Application | $25 | Valid for 180 days |
| CDL (new or renewal) | $97 | Ages 18–84, valid 8 years |
| CDL with HazMat | $61 | Valid 5 years (HazMat requires renewal) |
| Age 85+ | $25 | Expires after 2 years |
Texas ELDT Requirements
Since February 7, 2022, all new CDL applicants in Texas must complete Entry-Level Driver Training (ELDT) through an FMCSA-approved training provider. This is a federal requirement — no state can waive it. Texas DPS verifies ELDT completion electronically through the FMCSA Training Provider Registry (TPR).
ELDT is required for:
- Original Class A or Class B CDL
- Upgrading from Class B to Class A
- First-time School Bus (S), Passenger (P), or HazMat (H) endorsements
You must hold your Commercial Learner’s Permit (CLP) for at least 14 days before taking the skills test. Your CLP is valid for 180 days in Texas.
Texas CDL Test Format: What to Expect
The Texas CDL exam has two parts: knowledge tests (written) and a skills test (driving). The knowledge tests are computer-based, multiple-choice, and administered at Texas DPS offices or approved testing facilities.
Knowledge Tests Overview
| Test | Questions | Pass Score | Required For |
|---|---|---|---|
| General Knowledge | 50 | 80% (40 correct) | All CDL classes |
| Air Brakes | 25 | 80% (20 correct) | Class A & B (if vehicle has air brakes) |
| Combination Vehicles | 20 | 80% (16 correct) | Class A |
| HazMat (H) | 30 | 80% (24 correct) | HazMat endorsement |
| Tanker (N) | 20 | 80% (16 correct) | Tanker endorsement |
| Passenger (P) | 20 | 80% (16 correct) | Passenger endorsement |
| School Bus (S) | 20 | 80% (16 correct) | School bus endorsement |
| Doubles/Triples (T) | 20 | 80% (16 correct) | Double/triple trailers |
All Texas CDL knowledge tests follow FMCSA content standards from the Texas Commercial Motor Vehicle Drivers Handbook (DL-7C). The passing score is 80% on every test — no exceptions.
Texas Skills Test: Three Parts
The Texas CDL skills test is administered by DPS-approved Third-Party Testers (TPTs) — not directly at DPS offices. You must provide your own vehicle for the test, and it must be the same class of vehicle you’re applying for.
| Section | What It Tests | Details |
|---|---|---|
| 1. Pre-Trip Inspection | Vehicle safety knowledge | Verbally identify and explain critical components: engine, brakes, tires, lights, coupling systems |
| 2. Basic Vehicle Control | Backing and maneuvering | Straight-line backing, offset backing, parallel parking, alley dock |
| 3. On-Road Driving | Real-world driving | Lane changes, turns, braking, gear usage, speed management, traffic law compliance |
Texas skills test retake policy: If you fail any section, you only retake the failed section. The waiting period is a minimum of 2 days between retakes. Passed segments remain valid for 90 days or until 3 failures — whichever comes first.
What Makes Texas CDL Different from Other States?
The core CDL exam is federally standardized — the General Knowledge, Air Brakes, and endorsement tests cover the same material in every state. But Texas has specific characteristics that make driving here unique:
Texas-Specific Driving Conditions
- Vast distances: Texas is the largest continental state — driving from El Paso to Houston is over 740 miles, nearly the distance from New York to Chicago
- Extreme heat: Summer temperatures regularly exceed 100°F — tire blowouts, engine overheating, and heat-related equipment failures are major concerns
- Oil and gas industry: Texas is the #1 petroleum producer — HazMat and tanker endorsements are especially valuable here, with unique oilfield driving conditions
- Hill Country terrain: The Texas Hill Country (Austin, San Antonio area) features winding roads and elevation changes requiring careful speed management
- High-traffic urban centers: Houston, Dallas-Fort Worth, San Antonio, and Austin all rank among the most congested cities for freight traffic in the US
- Border commerce: Texas shares a 1,254-mile border with Mexico — commercial border crossings at Laredo, El Paso, and Hidalgo require specialized knowledge
- Hurricane season: Gulf Coast driving from June through November requires preparation for sudden severe weather, flooding, and evacuation routes
While the CDL knowledge test itself won’t ask you Texas-specific questions beyond what’s in the standard handbook, understanding these conditions will make you a safer driver and help you contextualize the safety rules you’re learning.

Texas CDL Frequently Asked Questions
How many questions are on the Texas CDL General Knowledge test?
The Texas CDL General Knowledge test has 50 multiple-choice questions. You need to answer at least 40 correctly (80%) to pass. The test covers vehicle inspection, safe driving practices, cargo management, CDL regulations, and more.
How much does a Texas CDL cost?
The total cost includes a $25 CLP application fee and a $97 CDL fee (for ages 18–84, valid 8 years). If you’re adding a HazMat endorsement, the CDL fee is $61 (valid 5 years). Additional costs include your DOT medical exam (typically $75–$150) and ELDT training ($3,000–$8,000 if attending a school).
What happens if I fail a Texas CDL knowledge test?
If you fail a knowledge test, you can retake it. Texas DPS requires a waiting period between attempts. If you fail the same test three times, your application may be voided and you’ll need to start over. We recommend using our practice tests until you consistently score above 80% before attempting the real exam.
Can I get a Texas CDL at 18?
Yes. Texas allows you to get a CDL at 18 for intrastate driving only (within Texas). You cannot cross state lines until you turn 21. The HazMat endorsement requires you to be at least 21, regardless of your license type.
Where do I take the Texas CDL skills test?
Texas CDL skills tests are administered by DPS-approved Third-Party Testers (TPTs), not directly at DPS offices. You can find approved testers through the Texas DPS website. You must provide your own vehicle for the test — it must match the class of license you’re applying for.
Is the Texas CDL test the same as other states?
The knowledge tests are based on the same FMCSA standards and cover the same material as in every other state. The Texas DPS uses the Texas Commercial Motor Vehicle Drivers Handbook (DL-7C), which follows the federal CDL manual closely. Questions about vehicle inspection, safe driving, cargo securement, and endorsements are standardized nationally. Your Texas CDL is valid in all 50 states.
