Prepare for the General Knowledge section of your Commercial Learnerʼs Permit (CLP) test.
New Hampshire has a robust manufacturing industry because of its generally business-friendly economic policies and its proximity to Quebec and Massachusetts, specifically Montreal and the Port of Boston. Of course, truckers play major roles in transporting products manufactured in New Hampshire and transporting goods from the Port of Boston to the rest of New England.
Several major highways and secondary roads are important for commercial transportation. Interstate 93 is one of New Hampshire’s most heavily used commercial routes. It begins at Canton, Massachusetts, continues through Boston and then through Concord and Manchester in New Hampshire, and ends at Saint Johnsbury, Vermont. Unfortunately, this highway is notorious for traffic bottlenecks near Boston. Other major commercial routes include Interstate 95 and U.S. Routes 3, 4, and 202.
Want to drive these roads and earn money in the process as a licensed commercial driver? One of your most important early steps is to pass the official General Knowledge written test on commercial driving theory. This is a necessary step to becoming eligible for a Commercial Learner’s Permit (CLP), which will allow you to practice commercial driving under supervision. And once you’ve become proficient at commercial driving, you can take the official skills test for a Commercial Driver’s License (CDL).
To prepare to pass this knowledge test, you should read the official New Hampshire CDL Driver’s Guide (New Hampshire CDL Handbook 2026) if you haven’t already done so. This manual contains all the information on which you’ll be tested. However, we believe that you should take additional steps to ensure that you retain the information and answer test questions on it accurately.
This free New Hampshire CDL permit practice test, one of several we offer, is based on the official New Hampshire manual, just like the official knowledge test. It’s up to date as of June, 2026. There are 20 multiple-choice questions on such topics as cargo management, driving on downgrades, emergency preparedness, and vehicle components. Unlike the official knowledge test, each question on this practice test comes with an available hint to suggest the correct answer, and an explanation of the correct answer. What this practice test doesn’t have is a time limit. Take as much time as you need to learn as much as you can. Consider using the test like an open-book test. Have a copy of the CDL Driver’s Guide open as you take the test so you can look up the correct answers to questions that puzzle you. You’ll learn more that way than by random guessing.
What to review before the CLP knowledge test and CDL endorsement practice
Based on recent Driving-Tests.org answers for this test family.
Review tire condition, tread, inflation, lug nuts, rims, and wheel-end problems caught during inspection.
Review engine controls, shifting, gauges, retarders, and warning signs that need attention before or during a trip.
Review axle weights, load balance, center of gravity, and how weight affects braking, steering, and rollover risk.
Review emergency stops, warning devices, brake failure, tire failure, and safe roadside procedures.
CLP and General Knowledge requirements before skills testing and endorsements
Start with General Knowledge for your NH CLP. Add Combination Vehicles, Air Brakes, or endorsement tests only when they match the license class and endorsements you need.
Passing the written test does not give you a CDL. After your CLP is issued, federal rules require you to hold it for at least 14 days before the CDL skills test.
Pick the right medical self-certification category early. If you drive non-excepted interstate, keep your DOT medical certification current with the state licensing agency.
ELDT may be required before Class A or B skills testing, first-time Passenger or School Bus endorsements, or the HazMat knowledge test. Your training provider submits completion through FMCSA's Training Provider Registry.
Use General Knowledge as the base, then move into the CDL tests that match your license class and endorsements.
