New Hampshire licenses commercial drivers through the Division of Motor Vehicles, which sits inside the state's Department of Safety rather than standing alone as its own department. That is a different structure from a state that runs its DMV as an independent agency, and it means commercial licensing shares administration with the state's other safety functions.
Every figure below names the document it came from, so you can check it rather than take our word for it.
Fees change without notice, so we do not repeat them here. Check New Hampshire Division of Motor Vehicles for the current cost.
The knowledge tests are set by federal rule, so the questions are the same wherever you sit them. What changes is the paperwork above.
The combination license.
The heavy straight vehicle license. Group B covers a single vehicle rating 26,001 pounds or more, or one towing a unit of 10,000 pounds or less.
The small vehicle license.
The knowledge test every commercial driver takes, whatever class or endorsement they are after.
Required before you may drive any commercial vehicle with air brakes.
Required for a Class A license. Coupling and uncoupling, off-tracking, trailer brakes and the handling of a vehicle that is jointed in the middle.
The H endorsement. Placarding, shipping papers, loading and segregation rules, and what to do when something leaks.
The N endorsement. Surge, baffles, bulkheads, high center of gravity and the way a part-full tank changes how a vehicle stops and turns.
The T endorsement. Coupling and uncoupling multiple trailers, converter dollies, crack-the-whip and the inspection points a second trailer adds.
The P endorsement. Pre-trip and post-trip checks on a bus, loading and unloading, standee lines, and handling passengers on the road.
The S endorsement, taken alongside the passenger endorsement. Danger zones, mirror adjustment, loading and unloading students, and railroad crossings.
A study drill for the pre-trip inspection.
New Hampshire is one of the smaller states by area, and that changes the practical side of testing more than anything else. Distances between testing locations are short compared with a large, rural state, so travel is rarely the obstacle it can be elsewhere. What does not change is the content of the knowledge tests themselves: they are federal, set out in 49 CFR Part 383, so the questions you need to know are the same ones a driver in a much bigger state is studying.
General knowledge is the one every commercial driver sits, and the pass mark is 80 percent, a federal figure rather than something New Hampshire sets on its own. It covers the broad syllabus set out in 49 CFR 383.111: driver fitness, basic vehicle control, cargo handling and the rest of the material every commercial driver is expected to know before touching a truck. Beyond that, the vehicle you plan to drive decides the rest. Air brakes require the air brakes test; without a pass, your license carries a restriction that bars air-braked vehicles outright. A trailer over 10,001 pounds brings combination vehicles into it as well.
From there sit the endorsements: tank vehicles, doubles and triples, passenger, school bus, and hazardous materials. Hazmat is the one to plan for separately, because it adds a Transportation Security Administration background check on top of the written exam, and that check runs on federal timing you cannot shorten by preparing harder for the test itself.
You need a commercial learner permit before New Hampshire will let you take the skills test, and federal rule sets a 14-day minimum wait between the permit and that test. Because testing sites are close together here, the main risk is not distance but leaving the knowledge tests too late in that window to allow for a retake.
Age limits are federal as well: 18 lets you drive commercially within New Hampshire, 21 is required before you can take a commercial vehicle across a state line.
Fees are left off this page deliberately. They change, and New Hampshire is the authority on the current number, not us. Check with the Division of Motor Vehicles before you go. What this site does cover is the test material: practice questions for every New Hampshire knowledge exam, each one linked to the rule or handbook page behind it.
Every question on every one of these is free, and each answer names the handbook page it came from.
Every question names the handbook, section and page it was read from, so you can check the answer instead of taking our word for it.
