The Idaho DMV CDL General Knowledge Test is one of the primary gateways to operating a commercial motor vehicle (CMV). Every CDL applicant must pass this exam regardless of license class, and success depends on achieving a minimum score of 80% on the exam. Our Free Idaho CDL Test Questions & Answers General Knowledge Practice Test No. 11 is based on the most recent Idaho Commercial Driver License Manual and federal and state requirements and is designed to help you pass on your first attempt. Our other users completed 22 Idaho practice tests today and 714 this week. Why let them have this advantage over you? Give yourself that same edge with our practice tests.
Designed to mirror how the real exam is written and presented, our practice tests differ greatly from the static study guides or outdated PDF packets that were once the go-to tools for learning. Idaho’s official exams often employ tricky wording and occasional double negatives that can trip up even the most well-prepared test-takers. However, our practice tests prepare you for those challenges. By presenting exam-style multiple-choice questions, immediate AI-driven feedback, and clear explanations that reinforce understanding as you go rather than holding all comments until the end, our learning methods far surpass those of yesteryear.

The official knowledge exam covers pre-trip inspections, safe vehicle operation, speed and space management, braking and shifting on long grades, hazard recognition, railroad crossings, emergency response, skid control, and fatigue management. Idaho drivers will face mountain passes, sudden winter weather, high desert heat, and long rural stretches where help may be far away. These practice tests help prepare you for such situations.
Drivers are also expected to understand federal drug and alcohol rules, including participation in the FMCSA Drug and Alcohol Clearinghouse, as well as Idaho’s medical self-certification requirements. Serious traffic violations, railroad crossing errors, or alcohol-related offenses can result in lengthy or permanent disqualification from commercial driving. Without question, there is a lot to know for the official exam.
Our practice test experts have intentionally filtered out the fluff and removed untested content to focus on what you’ll actually face on the exam. One of our most effective tools is the Challenge Bank, which tracks questions you miss and automatically brings them back in future sessions until mastery.
