New Hampshire Class C CDL Practice Questions and Guide

Prepare for a New Hampshire Class C commercial driver license with 100 original practice questions tied to the saved question bank. The set covers general knowledge, air brakes, hazardous materials, tank vehicles, passenger vehicles, and school buses. Class C applies to qualifying vehicles that do not meet the Class A or B weight groups but meet specified passenger, hazardous-material, or New Hampshire tank conditions. The specialty modules in this bank apply only when the vehicle, endorsement, or intended operation makes them relevant; this is broad scenario-based study rather than one applicant’s exact test list. Use the explanations to review inspections, braking, operating rules, tank dynamics, passenger safety, and licensing responsibilities. New Hampshire requirements can change, so this guide summarizes official state rules and federal guidance checked on September 18, 2026.

LICENSING GUIDE

What to know before you test

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

Start with the Class C vehicle group and the endorsement you actually need

New Hampshire places certain vehicles or combinations rated at 26,000 pounds or less in Class C when they are required to be placarded for hazardous materials, are designed to transport 16 or more persons including the operator, or meet the rule’s specified attached-tank capacity condition. Vehicles meeting the heavier Class A or B weight groups require the appropriate higher class. Passenger, school-bus, hazardous-materials, tank, and air-brake requirements depend on the vehicle and privileges involved.

Meet age and learner-permit conditions

New Hampshire generally does not issue a CDL to a person under 18. Interstate commercial driving requires age 21 under the federal rule cited here, and New Hampshire rules also set age 21 for a driver who intends to transport hazardous materials. A commercial learner permit requires a valid driver license, may be issued for no more than 180 days, and allows highway practice only with a CDL holder valid for the type of vehicle in the immediately adjacent seat.

Apply ELDT to the credential, not automatically to Class C

Federal Entry-Level Driver Training rules do not list a first-time Class C CDL by itself as an ELDT trigger. They do apply to a first-time passenger, school-bus, or hazardous-materials endorsement, with the required training completed through a provider listed on the Training Provider Registry before the applicable State skills or knowledge test. A CLP holder who must take a CDL skills test must also satisfy the federal CLP waiting rule before skills-test eligibility.

Know the New Hampshire examination standards

New Hampshire sets an 80 percent passing grade for each CDL knowledge examination. The rules list a 50-question general knowledge test, a 25-question air-brake test, 20-question passenger, tank, and school-bus tests, and a 30-question hazardous-materials test when those examinations apply. For vehicle inspection, a Class B or C straight truck must score no more than 8 points, a coach or transit vehicle no more than 9, and a school bus no more than 10. Basic control skills allow no more than 8 points, and the road test allows no more than 30, subject to immediate-failure events in the rules.

Bring accurate application information and proof

The commercial license or learner-permit application must include identifying and residence information, date of birth, the Social Security number unless a stated statutory exception applies, a signature, driver-qualification certifications, and other information required by the department. New Hampshire rules also require positive proof of identification before an original CDL is issued. Use the current DMV application instructions for the exact evidence required for your credential and circumstances.
