The CDL exam ensures that you’re ready to handle the unique responsibilities that come with driving large vehicles, from safety regulations to vehicle control. By passing this exam, you’re proving your readiness to take on one of the most vital roles in transportation.
What is the CDL exam?
The CDL exam is a comprehensive test designed to ensure you can safely and legally operate a commercial vehicle. Passing this exam is mandatory whether you’re looking to drive a truck, bus, or any other commercial vehicle. The test is split into two parts: a written knowledge test and a hands-on skills test. Both sections are designed to assess your readiness to handle the various challenges of commercial driving.
Here’s a quick overview of the types of CDL licenses and endorsements available:
- Class A: Allows you to operate any combination of vehicles with a total weight of over 26,000 pounds (with a towed vehicle weighing more than 10,000 pounds).
- Class B: Allows you to operate a single vehicle with a total weight of over 26,000 pounds or any such vehicle towing a vehicle not exceeding 10,000 pounds.
- Class C: For vehicles transporting 16 or more passengers or hazardous materials (hazmat).
In addition to your license, endorsements such as Tanker, Hazmat, and Passenger can help you qualify for even more driving opportunities, allowing you to specialize in specific areas.
CDL exam requirements
The requirements to take the CDL exam vary by state, but they all adhere to federal guidelines set by the Federal Motor Carrier Safety Administration (FMCSA). Meeting these requirements is the first step to becoming a commercial driver, whether you’re pursuing an intrastate or interstate career.
Here’s a breakdown of what you need to qualify for a Commercial Learner’s Permit (CLP) or a Commercial Driver’s License (CDL):
Minimum requirements for a CDL
To apply for a CDL or CLP, you must meet the following minimum requirements:
- Possess a valid, non-commercial driver’s license.
- Have one to two years of driving experience (depending on the state).
- Complete driver training from an FMCSA-approved provider if applying for a Class A or Class B CDL.
- Be at least 18 years old to drive within your state (intrastate driving).
- Be at least 21 years old to drive out-of-state (interstate driving) or transport hazardous materials.
- Provide proof of U.S. citizenship or lawful permanent residency. Accepted documents include:
- Social Security
- cardBirth certificate
- Valid passport
- Green card
- Be able to speak and read English proficiently (per 49 CFR 391.11(b)(2)).
- Submit a DOT medical card after passing a DOT physical exam.
- Have a clean driving record and pass required background checks, especially for certain endorsements.
Federal CDL application requirements
Before applying for a CDL, you must first hold a CLP for a minimum of 14 days (specific state requirements may differ). In addition to the written tests, you’ll need to pass a road skills test and any additional exams for endorsements.
Here are some key federal regulations to be aware of:
- One CDL Rule: You are only allowed to hold one CDL at a time to prevent drivers from hiding poor driving records by applying in multiple states.
- No Texting Rule: Texting while operating a commercial vehicle is prohibited.
- Medical Certification: Commercial drivers must self-certify their medical status and use authorized medical examiners listed on the FMCSA National Registry.
Physical and medical requirements
Driving a commercial vehicle comes with physical demands, such as long hours on the road and handling heavy cargo. To ensure drivers are medically fit, a DOT physical exam is mandatory. The medical examiner will check for the following:
- Vision: 20/40 visual acuity in each eye (with or without corrective lenses) and a field of vision of at least 70 degrees in each eye.
- Hearing: The ability to hear a forced whisper at a distance of at least five feet in one ear (hearing aids are permitted).
- Diabetes: Drivers who require insulin injections do not qualify; however, those on oral medications can still pass.
- Blood Pressure: Drivers with blood pressure below 140/90 will receive a two-year medical card. Higher blood pressure levels may lead to shorter certification periods or disqualification.
- Sleep Apnea: If you have sleep apnea, you must provide documentation showing the condition is under control, such as a recent sleep study or a note from your doctor.
Structure of the CDL exam
The CDL exam has two main sections: a written knowledge test and a skills test. Getting familiar with how each part works will make it easier for you to prepare and feel more confident on exam day.
The written knowledge test
The written part of the CDL exam checks your knowledge of topics such as general driving information, air brakes, and combination vehicles. You’ll answer multiple-choice questions on things like driving laws and safety procedures. The specific sections of the test can vary depending on your state, but typically include the following:
- General Knowledge: Covers topics like vehicle inspections, emergency procedures, driving in different weather conditions, mandatory rest breaks, and basic vehicle controls (braking, shifting, etc.).
- Air Brakes: Focuses on the components and operation of air brakes, including brake system parts, inspection, and usage.
- Combination Vehicles: Tests your knowledge of tractor-trailers and other combination vehicles, with questions about coupling/uncoupling, inspecting combination vehicles, and handling turns and backing procedures.
To pass the written test you’ll need to score at least 80% on each section. If you don’t pass on your first attempt, many states allow you to retake the exam after a waiting period, but it’s important to check your state’s specific guidelines.
The skills test
The next step is passing a skills test to get your full CDL. This is a hands-on test with three main parts:
- Pre-trip Inspection: This is where you’ll inspect critical vehicle systems—such as brakes, lights, and tires—to ensure the vehicle is road-ready.
- Basic Vehicle Control: Demonstrate your control of the vehicle through specific maneuvers, such as reversing, parallel parking, and making tight turns.
- On-road Driving: This section tests your ability to drive the vehicle in real-world conditions, including highways, city streets, and various road environments.
Each part of the test is meant to ensure you can safely operate a commercial vehicle, and you’ll need to pass all sections to earn your CDL.
Preparing for the CDL exam
Preparing thoroughly is essential to passing the CDL exam on your first try. With the right approach and resources, you can feel confident and ready.
Here are some helpful tips to guide you through your study and practice:
- Study materials: Your state’s CDL manual is your most important resource. Study it carefully, as it covers all the topics you’ll be tested on, from driving laws to vehicle safety procedures. Additionally, online practice tests and study guides can help you focus on the most important topics and get comfortable with the test format.
- Training programs: Many truck driving schools offer comprehensive CDL training programs. These programs not only prepare you for the written knowledge test but also provide hands-on experience with the skills test. FMCSA-approved training programs are especially useful for those pursuing Class A or Class B licenses.
- Hands-on practice: There’s no substitute for time behind the wheel. The more driving experience you gain, the more confident you’ll be during the skills test. Some training programs even offer simulation tests to help you prepare for specific maneuvers, like backing up or parking in tight spaces.
By sticking to a well-organized study plan and getting lots of hands-on practice, you can greatly increase your chances of passing the CDL exam on your first try. A clear plan helps you focus on what’s important, and real-world practice builds your confidence behind the wheel, setting you up for success on exam day.
Common CDL exam challenges and how to overcome them
Taking the CDL exam can feel overwhelming, but with the right preparation and mindset, you can tackle any challenges that come your way. Here are some common obstacles CDL applicants face and how to overcome them:
Test anxiety
Feeling nervous before an exam is completely normal. The key is to stay calm and focused. If you start feeling overwhelmed during the test, take a few deep breaths and remind yourself that you’ve prepared for this. Break the test down into smaller parts and focus on answering one question at a time.
Mastering the skills test
The skills portion of the CDL exam can be intimidating, especially if you’re new to driving commercial vehicles. Practice is your best friend here. Make sure you get plenty of time behind the wheel, especially focusing on maneuvers like backing up, parallel parking, and making tight turns. If certain skills are giving you trouble, target those areas in your practice sessions. And don’t hesitate to ask instructors for extra guidance—they’re there to help!
Understanding the material
There’s a lot of information to absorb for the CDL exam, from driving regulations to vehicle maintenance. It’s important to pace yourself and break the material down into smaller, manageable sections. Focus on areas where you’re struggling, and use study guides and practice tests to reinforce your understanding.
Tips for passing the CDL exam
Looking for some quick tips to help you pass the CDL exam? With the right preparation and strategy, you’ll be ready to succeed. Here are a few key pointers to guide you:
Get your state’s CDL manual and study it
Each state has its own CDL manual that covers everything you’ll need to know for the exam. Download your state’s manual from the Department of Motor Vehicles (DMV) website, or pick up a hard copy at your local DMV office. Once you have the manual, don’t just skim it—read it thoroughly at least once to familiarize yourself with the key concepts.
After that first read-through, break the manual down into smaller sections and start studying those in detail. Use CDL practice tests to reinforce your knowledge and identify areas where you might need extra focus.
Memorize and understand the pre-trip inspection
The pre-trip inspection is a crucial part of the CDL exam, and it’s easy to underestimate just how much detail goes into it. While memorizing the checklist is important, you also need to understand how each part of the truck works and why it’s essential for safety. Being able to explain how to check the brakes, tires, and lights—along with other key components—will help you ace this portion of the test.
Memorization can help with definitions, but real understanding will ensure you aren’t caught off guard by tricky questions or unexpected scenarios during the skills test.
Pick techniques that match your learning style
Everyone learns differently, so it’s important to find study strategies that fit your style. Some people benefit from using flashcards or practice tests, while others might prefer creating songs or rhymes to help memorize key terms. There are also plenty of study apps that can make learning easier and more engaging.
If you prefer a hands-on approach, consider asking a friend or family member to quiz you. Not only does this help reinforce what you know, but it also helps you get used to explaining concepts out loud—a skill you’ll need for the skills test.
Make sure you practice often
Just because you’ve taken one practice test doesn’t mean you’re all set! One of the best ways to fully prepare for the CDL exam is by taking multiple practice tests. Many online resources offer a variety of practice questions and test modes that simulate the real exam experience. Not only do these practice tests help you get familiar with the types of questions you’ll face, but they also give you the chance to test your knowledge in a low-pressure setting.
The more practice tests you take, the more comfortable you’ll be when exam day comes around.
What happens once you pass your CDL exam?
Once you pass the CDL exam, you’re officially on your way to starting your career as a commercial driver. But the journey doesn’t end here—there are a few more steps to complete before you hit the road.
First, you’ll receive your CDL, which qualifies you to drive commercial vehicles based on the class of license you obtained (Class A, B, or C). If you’re looking to specialize in a certain type of driving, now is the time to consider applying for additional endorsements, like Hazmat, Tanker, or Passenger.
Remember, having a CDL means you’ll need to stay compliant with DOT regulations. This includes keeping your medical card up to date, maintaining a clean driving record, and staying informed about any new regulations.
