What is the CDL Exam?
The CDL exam is the test you must pass to drive commercial vehicles in the United States. Every state requires it. The exam has two parts: written knowledge tests and a driving skills test.
Everyone starts with the General Knowledge written test. You may also need extra written tests for your vehicle type and endorsements. Pass all your written tests and you get a Commercial Learner's Permit (CLP). The permit lets you practice driving with a licensed CDL holder. Then you take the skills test.
You take the exam at your state DMV — the state office that issues driver's licenses. The questions follow federal rules from the FMCSA, the Federal Motor Carrier Safety Administration. Question counts, passing scores, and fees can vary a little from state to state.
How Do I Study for the CDL Exam?
1. Take Practice Tests
Test yourself with free practice questions right here on our website. This helps you identify weak areas and get comfortable with the exam format.
2. Download the App
The CDL Help app includes free practice sections — subscribe to unlock all 2,500+ questions, bookmarking, progress tracking, and study tools.
3. Focus on Weak Areas
Review questions you got wrong, read the explanations, and retake tests until you consistently score above the passing threshold (usually 80%).
4. Enroll in a CDL Truck Driving School
Once you pass the written permit exam, enroll in an accredited CDL training program to complete your behind-the-wheel training and prepare for the driving skills test.

Class C
Required for vehicles that don't fit Class A or B but are designed to transport 16+ passengers or carry hazardous materials. Includes small HazMat vehicles and passenger vans.
New English Language Proficiency Enforcement — We've Got You Covered
In 2025, federal authorities began strictly enforcing English language proficiency rules under 49 CFR §391.11. Drivers who cannot show enough English at a roadside inspection are placed out of service. Hundreds already have been.
CDL Help has included a built-in English practice feature since 2022 — long before the enforcement wave. It helps you genuinely learn the material and the language together. Road safety starts with comprehension: reading signs, answering inspectors, and communicating clearly on the job.

Your Path to a Commercial Driver's License
To get a CDL, you must first study for and pass the permit exam at the DMV. After you receive your permit, you can take commercial vehicle driving classes and complete the required training. The final step is passing the official driving exam to earn your CDL. Our practice tests help you prepare for the DMV permit exam with real-style questions, and we also provide extra study materials and helpful resources to guide you through the process.
