Texas Class C CDL Practice Questions

This Texas Class C CDL practice set contains 100 original English-language questions linked to the current saved question bank. It covers general knowledge, air brakes when applicable, hazardous materials, conditional tank-vehicle scenarios, passenger vehicles, and school buses. Texas Class C applies to vehicles that are not Class A or B when they are designed to transport 16 to 23 people including the driver or are used to transport hazardous materials that require placards. Because endorsements, air-brake equipment, and tank configurations depend on the intended operation, this mixed set is broader than the tests every individual applicant will take. Texas CDL and CLP knowledge examinations are administered in English only as of June 1, 2026. Use the explanations to review safety concepts and verify your own endorsement, medical, training, and test-vehicle requirements with Texas DPS.

LICENSING GUIDE

What to know before you test

Use this overview together with the latest official guidance linked below.

Know what Class C covers

Texas defines a Class C CDL for a single vehicle or combination that does not meet Class A or B definitions when the vehicle is designed to transport 16 to 23 people including the driver, or when it transports hazardous materials in quantities that require placarding. A vehicle designed for 24 passengers or more is placed in Class B, and qualifying heavy single vehicles or heavy combinations fall into Class B or A. Class C authority does not automatically provide passenger, school-bus, hazardous-materials, tank, or unrestricted air-brake qualifications; the needed endorsements and restrictions depend on the actual vehicle and operation.

Build the CLP and testing sequence

For a Texas Class C CDL that requires a commercial learner permit, hold the CLP for at least 14 days before the CDL skills test. Texas lists the knowledge-test order as Texas Commercial Rules, General Knowledge, Combination for Class A only, Air Brake when applicable, and endorsements. FMCSA does not list first-time Class C licensure by itself as an ELDT trigger, but first-time passenger, school-bus, or hazardous-materials endorsements are covered by ELDT, subject to stated exceptions. After the applicable waiting period and training, the driving test includes vehicle inspection, basic vehicle control, and a road test. Since June 1, 2026, Texas CDL and CLP knowledge examinations are in English only and interpreters are prohibited.

Prepare documents and medical status

Before visiting a Texas driver license office for a CLP or CDL transaction, review the current DPS requirements. Applicants generally need the CDL application, identity and citizenship or lawful-presence evidence, a Social Security number, the appropriate self-certification, and medical qualification when the selected operating category requires it. Texas receives medical certification information electronically through the National Registry II process and no longer accepts paper medical certificates. Medical and self-certification rules vary with interstate or intrastate and excepted or non-excepted operation, so choose the category that matches the work you will actually perform and confirm that required medical information has reached DPS.

Use the practice bank as a review tool

The 100 questions on this page use four answer choices because that is the site practice format, not a statement about the number or format of questions on a Texas examination. Review missed answers by module, then return to the Texas Commercial Motor Vehicle Driver Handbook and the relevant DPS or FMCSA guidance. For Class C, concentrate on general commercial-driver rules plus the endorsement or equipment modules that match your actual vehicle: passenger or school-bus operation, placarded hazardous materials, air brakes when equipped, and tank rules when a Class C hazardous-materials vehicle uses qualifying tanks. Passing knowledge tests is only one step; issuance also depends on applicable documents, CLP restrictions, training, and skills testing.

REQUIREMENTS OVERVIEW

Texas CDL Class C requirements

Requirements depend on the applicant and can change. Verify each item with the cited agency.

age

Texas CDL or CLP applicants whose operating category determines minimum age and medical status.

Texas DPS lists age 21 or older for non-excepted interstate commerce. Some excepted interstate and intrastate commercial categories may be available from age 18, subject to their restrictions and medical rules.

documents

Applicants seeking a Texas commercial learner permit or Class C CDL.

DPS requires the applicable CDL application and identity/citizenship or lawful-presence documentation; the CLP process also requires a Social Security number, self-certification, and valid medical qualification when the selected operating category requires it.

tests

Texas Class C CDL applicants and CLP holders preparing for passenger, school-bus, hazardous-materials, air-brake, or other applicable testing.

Texas identifies Commercial Rules and General Knowledge first, followed by Air Brake when applicable and required endorsement knowledge tests; Combination is listed for Class A only. The CDL driving test includes vehicle inspection, basic vehicle control, and a road test when a skills test is required. Knowledge examinations are in English only as of June 1, 2026.

passing

Applicants seeking issuance of a Texas Class C CDL or a related passenger, school-bus, or hazardous-materials endorsement.

Applicants must successfully complete the knowledge tests that apply to their license and endorsements and, when required, pass the CDL driving-test components after satisfying the CLP holding period and applicable training requirements. This page does not state an unsupported numeric passing score.

applicability

Texas Class C applicants and drivers adding P, S, H, air-brake, or tank qualifications.

Texas Class C applies to vehicles outside Class A and B that are designed for 16 to 23 people including the driver or transport placarded hazardous materials. FMCSA ELDT requirements apply to first-time S, P, or H endorsements, subject to listed exceptions; first-time Class C licensure by itself is not listed as a Class A/B ELDT trigger. Air-brake and tank material on this page applies only when the actual Class C vehicle or load makes those rules relevant.
