Texas is the second-largest CDL-issuing state, and two structural quirks catch most candidates off guard. First, CDLs are handled by the Texas Department of Public Safety (DPS), not TxDMV — a split that diverges from the DMV model used in most states. Second, DPS leans heavily on a private network of Third Party Skills Testing (TPST) providers; if you train at a TPST-certified school, you may complete the entire CDL flow, knowledge tests included, without ever stepping into a state-run Mega Center.
The commercial knowledge test runs in English or Spanish only — there is no direct Spanish skills exam. Interpreters are prohibited during the drive test, though select offices offer interpreter-by-request for the knowledge portion at the DPS's discretion. Texas also maintains its own Class C commercial CDL definition for specific small-vehicle and passenger configurations, which differs from the federal Class C designation most other states use.
Fees are bundled: the original CDL fee is $97 for an 8-year term, or $61 for the 5-year HazMat-endorsed cycle. The CLP is a separate $25, valid 180 days and renewable once before expiration. See the fees table on this page for the full DPS-sourced breakdown.
License pathway and CLP mechanics
The license pathway itself is conventional. You apply for a Class A, B, or commercial Class C. You file form CDL-1, pick a medical self-certification category on CDL-4, CDL-5, or CDL-10, and pay the Commercial Learner Permit fee of $25. The CLP is good for 180 days and can be renewed once before expiration. You must hold the CLP for a minimum of 14 days before taking the skills test, and you must complete Entry Level Driver Training first, because ELDT has been a federal prerequisite to skills testing since February 7, 2022. Knowledge tests run in a fixed sequence: Texas Commercial Rules, General Knowledge, Combination (Class A only), Air Brakes if applicable, then endorsements.
Language rules — knowledge vs. skills
One place Texas diverges sharply from some peers is language. DPS offers the commercial knowledge test in English or Spanish, and nothing else — California, for comparison, offers commercial knowledge tests in six languages. Interpreters are prohibited during the skills test, and neither the applicant nor the examiner may communicate in a language other than English while the driving portion is running. The flip side is that Texas takes Spanish seriously at the study stage: the DL-7C handbook is published in a full Spanish edition, so bilingual candidates can study natively and sit the written exam in Spanish without penalty.
Farm exemption and Farm-Related Service Industry waiver
The farm exemption is broader in Texas than in most states, which matters for anyone operating a ranch or a family farm. A vehicle controlled and operated by a farmer, used to haul agricultural products or equipment within 150 air-miles of the farm, not operated for hire, and not placarded hazmat does not require a CDL. Ranchers count as farmers for this purpose, and the farmer's employees are equally exempt. You still need a non-commercial Class A or B driver license that matches the vehicle's GVWR, filed on the CDL-2 non-CDL application form. A narrower Farm-Related Service Industry (FRSI) waiver lets DPS issue a restricted Class B or Class C CDL to employees of custom harvesters, agri-chemical businesses, and livestock feeders without knowledge or skills testing.
Military waivers: CDL-3A and CDL-3B
Military applicants have a separate track. Form CDL-3A waives the skills test for service members who operated a CMV-equivalent military vehicle for at least the two years immediately preceding discharge, and CDL-3B waives both the knowledge and skills tests for a qualifying subset. Both waivers exclude the School Bus (S) and Passenger (P) endorsements, so veterans aiming at school bus or transit careers still sit both exams in person.
Out-of-state and international transfers
If you already hold a valid CDL from another U.S. state, U.S. territory, or Canada when you move to Texas, you have 90 days to convert it. The written and driving exams are waived and you pay the standard $97 CDL fee after a vision check.
Mega Centers and the TPST channel
The testing offices listed on this page are the five canonical Mega Centers we verified as administering CDL skills tests: Houston North, Dallas Garland, Fort Worth, Austin Pflugerville, and San Antonio Leon Valley. San Antonio Leon Valley is Class B only, so Class A candidates in the San Antonio metro typically schedule through a TPST provider. The TPST channel is the default path for most school-trained candidates; the state-run Mega Centers absorb walk-in applicants, military waiver cases, and candidates without access to a certified school.
