Delaware Class A CDL Mixed Practice Questions and Licensing Guide

Prepare for Delaware Class A commercial-driver licensing with 100 original mixed practice questions. The bank includes general knowledge plus air brakes, combination vehicles, hazardous materials, tank vehicles, doubles/triples, passenger, and school bus modules. Topics include inspection, braking, cargo, coupling, commercial operating rules, hazards, passenger safety, tank dynamics, signs, speed control, collisions, and licensing responsibilities. These are study questions, not official Delaware DMV exam items, and the 100-question format is not an official test blueprint. Delaware DMV says every CDL applicant takes at least the General Knowledge test, with additional tests depending on license class and endorsements. Use this bank alongside the current Delaware CDL manual, DMV licensing pages, and applicable FMCSA requirements.

LICENSING GUIDE

What to know before you test

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

Confirm that Class A is the correct CDL class

Delaware DMV defines Class A for a vehicle combination over 26,000 pounds when the towed vehicle is over 10,000 pounds, using registered, actual, or gross vehicle weight rating measurements described by the state. FMCSA's federal Class A definition similarly covers a combination with a gross combination weight rating or weight of at least 26,001 pounds when the towed unit exceeds 10,000 pounds. Delaware lists a minimum age of 18 with one year of driving experience for intrastate Class A, B, or C operation, while age 21 with one year of driving experience applies for broader operation such as interstate driving. Applicants should match the license class to the vehicle they intend to operate rather than treating every commercial vehicle as Class A.

Separate required Class A testing from conditional modules

Delaware states that every CDL knowledge-test applicant completes at least the General Knowledge test, with additional testing based on license class and endorsements. This mixed practice bank intentionally includes eight modules, so not every module represents a requirement for every Class A applicant. FMCSA identifies T for doubles/triples, P for passenger, N for tank, H for hazardous materials, X for combined tank and hazardous-material authority, and S for school bus. Passenger and school-bus endorsements require knowledge and skills testing, while the other listed endorsements use knowledge testing. Air brakes are not an endorsement; FMCSA describes restrictions that apply when an applicant does not qualify to operate a CMV with a full air-brake system.

Complete ELDT and prepare for the skills test when required

Federal Entry-Level Driver Training rules apply to drivers obtaining a Class A or Class B CDL for the first time, upgrading from Class B to Class A, or obtaining certain endorsements for the first time. Delaware explains that an entry-level applicant must complete required theory and behind-the-wheel training from a registered provider before taking the applicable CDL skills test; hazardous-material applicants must complete the applicable ELDT before the H endorsement knowledge test. Delaware's modernized CDL skills test includes three segments: pre-trip vehicle inspection, basic control skills, and the road test. DMV says applicants must pass the full skills test to receive the CDL, and the state began using the modernized test at all locations on February 26, 2025.

Handle CLP supervision, self-certification, and medical status

Delaware says a driver holding a commercial learner's permit must be accompanied by a properly licensed CDL driver while operating the commercial motor vehicle being used for training. The state also requires all CLP and CDL holders and applicants to self-certify their commercial driving status. Medical-certificate submission depends on the self-certification category, so applicants should use Delaware DMV's current category guidance for their operation rather than assuming one medical-document rule applies to every driver. A Delaware CLP is valid for one year and cannot be issued or extended beyond one year from the original issuance date. These administrative requirements are separate from the subject-matter practice in the 100-question bank and should be checked directly before applying or testing.

applicability

Delaware Class A applicants using this mixed practice bank

The mixed bank contains General Knowledge plus air brakes, combination vehicles, hazardous materials, tank vehicles, doubles/triples, passenger, and school-bus material. Not every module applies to every Class A applicant: endorsements and restrictions depend on the vehicle, cargo, passenger operation, brake system, and authority the driver seeks. Federal ELDT applies to first-time Class A applicants, Class B-to-A upgrades, and specified first-time endorsements under the federal rules.
