Did you know that New Hampshire law requires drivers to switch on their headlights whenever rain, snow, or fog impairs visibility? This rule helps improve visibility for everyone on the road. It also applies to commercial drivers, who carry an even greater responsibility for safety. Whether you transport passengers or haul hazardous materials, it is crucial to drive carefully whenever the weather reduces visibility. Safe driving practices and other aspects of commercial driving theory are thoroughly explained in the New Hampshire Commercial Driver’s License Manual (New Hampshire CDL Handbook 2025). This official resource should not be missing from your toolkit.

Our New Hampshire CDL Class B Practice Test closely reflects the content and format of the official general knowledge exam. Updated for December 2025, this intuitive tool has 50 questions. Each question has multiple answer choices, but only one is correct. You must score 80% or higher to pass, leaving little room for error.

I was turned away from the NH DMV because I needed ELDT training.
I was turned away from the NH DMV for a CDL C with Hazmat Endorsement because I needed ELDT training. I was super annoyed that I had to do this. Upon starting the courses, I learned it was a bunch more studying of the CDL Manual. I only studied what I thought was applicable to CDL C on my own. This prepared me way more than expected and thanks to driving-tests.org I learned a LOT and passed my CDL C and Hazmat Exams first try! I sent my brother a link and he signed up on this site as well. Anyone looking to be fully prepared to take a CDL exam or endorsement exams, I Highly recommend this site.

Easily passed the CDL Class A knowledge test.
I easily passed the CDL Class A knowledge test! The training material was incredibly helpful and the practice test questions were nearly identical to the actual exam. There is no reason to look anywhere else for training for your CDL knowledge tests!

The process was very easy to get started. It was step by step all the way through. I passed hazmat and tanker first try within just 2 days of using the software.

This program gave me all the tool….
This program gave me all the tool necessary to pass my hazmat and tankers endorsement tests. I was able to study and take the practice tests over and over right up to the morning of my tests and I passed on the very first try. I would highly recommend this program to anyone looking to obtain any kind of CMV license or endorsements. Thanks again to Driving-Tests

Thanks!
Most of the questions here are on the actual test, however the real exam has trickier questions in which multiple answers shown would be correct. Instead of being able to select all of the above they are looking for 1 specific answer. This should be reflected for realism on some of the questions and tests presented here. Also I encountered a question about turns with turn lane 1 and 2 presented at an intersection, or turning from a 4 lane Hwy to a 2 lane divided hywy. I passed all of the tests i.e. general knowlege at 40 out of 50 (due to trickier questions), air brakes 100% and combination vehicles 100%. The air brakes exam and the combination vehicles exam was just as presented in the testing practice package. Passing the tests and obtaining my cdl learners permit in a short amount of time should show the true power of this method of learning.

Really great explanation!
Great service! I bought 7 days for ELDT CDL A theory, just for learning and certification of ELDT. There is a video course with good pictures and voice in same time. And you can download the PDF for own it. After theory you must have finished testing marathon about 700 questions with 100% right. This marathon organized so cool. You don't need remember any wrong answers because they are saving for answering again later. After marathon you mast do exam. I did with 92% right. Awesome. But I did mistake about my schedule for study and I had to pay again for 7 days to save my progress and finish studying. You have to be accurate with it and will plan your study smarter than me. There is about 12 hrs of video and after that marathon with 700 questions. It may be necessary 5-7 full days of study. Or you can pay in advance for 30 days study. It's cost no to much. After exams they automatically send you certificate and data to TPR (DMV also) and you can check immediately. Thanks for a great service! I will recommend you!
