CDL Practice Test — CDL Help Pass your CDL exam on the first try. CDL Help is #1 CDL practice test app for Class A and Class B Commercial Driver’s License preparation. Study 1000+ real-style questions offline, in 10 languages, with detailed explanations for every answer. PRACTICE TESTS INCLUDED Core CDL Tests: • General Knowledge — Vehicle rules, safe driving, cargo handling, vehicle inspection. Required for all CDL applicants. • Combination Vehicles — Coupling/uncoupling, rollover prevention, combination vehicle inspection. Required for Class A. • Air Brakes — System components, dual air brakes, inspections, proper usage. Endorsement Tests: • HazMat (H) — Hazardous materials handling, placarding, and emergency response. • Tanker (N) — Safe loading/unloading, surge effects, and tanker driving techniques. • Doubles & Triples (T) — Multi-trailer coupling, safe driving, and inspection. Bonus: Pre-Trip Inspection guide with detailed walkaround procedures. SMART STUDY FEATURES • Express Mode (key questions) or Full Mode (all questions) • Flashcards for quick review and repetition • Reading Mode to study chapter by chapter • Text-to-Speech — hear questions read aloud to practice listening comprehension • Bookmark questions for later review • Frequently Missed — automatically tracks your weak spots • Shuffle mode to test true understanding • Set Your Exam Date — daily study goals with countdown • Weekly and daily stats — questions answered, accuracy, study time • Category breakdown — see exactly where you need more practice • State-specific CDL information for all 50 states • Detailed explanations based on federal FMCSA regulations LEARN CDL + LEARN ENGLISH — AT THE SAME TIME Starting in 2026, FMCSA requires all CDL exams to be taken in English only. Roadside inspectors now enforce English proficiency under 49 CFR 391.11 — over 13,000 drivers have already been placed out of service for failing the two-step ELP assessment. CDL Help is built for this new reality. Every question displays in English alongside your native language — so you learn CDL regulations and build English proficiency together. Toggle between languages with one tap to understand every term, every sign, and every rule — the same way you'll need to on the road. This isn’t just about passing a test. It’s about keeping our roads safer. When you can read highway signs, communicate with inspectors, respond in emergencies, and complete reports in English — you protect yourself, your CDL, and everyone sharing the road. Supported languages: English, Spanish, Russian, Chinese, Arabic, Portuguese, Korean, Turkish, Ukrainian, Uzbek. Start today — download CDL Help and earn your CDL with confidence.

It will be cool if you add a feature that shows whether the test passes or not. Right on the list of quizzes.Because sometimes I was confused about which quiz I passed.

This app is a complete disappointment and a potential safety hazard. I use CDL Help to prepare for the CDL test, and honestly, it’s infuriating.The test questions and answers are not just incorrect but DANGEROUS. For example, the app states that you can open a hot engine to check some fluid, and it marks this as the correct answer! But just below in the explanation, it contradicts itself and says you should never do that. How can such inconsistencies be allowed in a learning tool, especially when safety is at stake?I paid for this app expecting quality content, but instead, I get nonsense that could cost lives on the road. The questions are misleading, the answers make no sense, and studying becomes a frustrating battle against ridiculous instructions.Developers, fix these mistakes, because with this kind of “learning,” your users are more likely to cause an accident than pass their exams. Right now, CDL Help is nothing more than a paid trap for unsuspecting drivers, not a reliable study tool.

Thank you for your feedback! We understand that some questions might seem counterintuitive at first, but we assure you that all questions in CDL Help are based on official Commercial Driver Handbooks.To verify this information yourself, follow these steps:1. Open Google and search for "California Commercial Driver Handbook".2. Click on the first link, which should direct you to the official California DMV website.3. Open the PDF version of the handbook.4. Go to page 70 (you can use the page selector at the top if you are viewing the page on a computer).5. Find the section titled "Engine Coolant", where this information is explained in detail.Clarification of the question:The handbook states that some vehicles have sight glasses, see-through coolant overflow containers, or coolant recovery containers, which allow drivers to check the coolant level even when the engine is hot.This is why the correct answer in our app states that you can check the coolant level of a hot engine.However, this does NOT mean that you should remove the radiator cap while the engine is hot. The handbook explicitly warns against this, as it can be dangerous due to pressurized steam and boiling coolant.Why this question is included in our database:This specific question and answer format is commonly found on real CDL exams, which is why we have included it in our database in this exact form. While the explanations might need better clarification, the question and the answer are correct and can be found on various exams.Continuous Improvement:We have a very large database of questions, and thanks to valuable feedback like yours, we can identify inconsistencies and make improvements. Based on this, we will be enhancing the clarity of question descriptions and adding more detailed explanations where necessary.We acknowledge that this question may seem unclear at first, and we appreciate your feedback. Our team is constantly working on improving the clarity of our questions, and a major update is coming by the end of the month.If you need further clarification, feel free to reach out to us via email, and we’d be happy to provide additional resources. Your input helps us make CDL Help even better—thank you!

I subscribed for $31 for a whole month, the application worked for only 2 days and it is no longer possible to open it! I tried to update, there were no updates! Deleted and downloaded again, all tests are closed and the subscription just disappeared! They don't return the money!

- Language & translations - Fixed issues that could force the app into the wrong language, improving language selection and translation consistency. - Flashcards & reading - Fixed a bug where using bookmarks could unexpectedly jump you back to the first card. - Removed non-working “More” menu buttons from flashcards and reading screens to reduce confusion and clutter. - Quizzes & exams - Fixed an exam countdown timer issue where timers could overlap by canceling the previous countdown before starting a new one. - Improved completion tracking so the app no longer logs a “test abandoned” event after you’ve actually finished the entire quiz. - Added stronger error logging when images fail to load in quizzes and flashcards to help diagnose image display problems. - Links & safety checks - Added rate limiting for the “Rate the app” link to prevent it from being triggered too frequently. - Data update - Updated the database to improve how question image paths are stored and handled for more reliable image loading.
