Getting your Commercial Driver's License opens doors to a stable career with competitive pay. Whether you're eyeing long-haul trucking, delivery services, or passenger transportation, understanding the CDL process can save you time and money. Here's everything you need to know about obtaining your CDL in 2025.
CDL Classes Explained: A, B, and C Licenses
Before you start the application process, you need to know which CDL class fits your career goals. The Federal Motor Carrier Safety Administration (FMCSA) recognizes three main classes, each designed for different vehicle types.
Class A CDL: For Heavy Combination Vehicles
A Class A license is what you need if you're planning to drive tractor-trailers or any vehicle combination where the trailer weighs over 10,000 pounds. This is the most versatile CDL and what most people think of when they picture truck drivers. With a Class A, you can haul freight across state lines, operate tanker trucks, or drive flatbed trailers. You can also drive Class B and C vehicles with the proper endorsements.
Class B CDL: For Single Large Vehicles
Class B covers straight trucks, large buses, and segmented buses where the vehicle itself weighs 26,001 pounds or more. Think city buses, dump trucks, or delivery trucks. If you're interested in becoming a school bus driver or operating a cement mixer, this is your license. You'll also be able to drive Class C vehicles with the right endorsements.
Class C CDL: For Specialized Vehicles
Class C might seem like the "smaller" option, but it's required for vehicles carrying hazardous materials or designed to transport 16 or more passengers (including the driver). This includes passenger vans, small hazmat trucks, and certain specialty vehicles. Even though these vehicles are under the 26,001-pound threshold, federal regulations require a CDL due to safety concerns.
Understanding CDL Endorsements
Once you know your license class, consider what endorsements you'll need. Endorsements like H (Hazmat), N (Tank Vehicle), P (Passenger), S (School Bus), and T (Double/Triple Trailers) expand what you can legally drive. Each requires additional testing, but they significantly boost your employability.
The CDL Application Process Simplified
Getting your CDL isn't as complicated as it might seem, but it does require meeting specific federal and state requirements. Here's how the process typically unfolds.
Step 1: Meet the Basic Requirements
First, you must be at least 18 years old to drive commercially within your state, or 21 for interstate commerce. You'll need a valid regular driver's license, and your driving record should be relatively clean. Most states will disqualify applicants with recent DUI convictions or multiple serious traffic violations.
Step 2: Obtain Your Commercial Learner's Permit (CLP)
Before you can take the CDL skills test, you need a CLP. Visit your local DMV office with proper identification, proof of residency, and your Social Security card. You'll also need to pass a Department of Transportation (DOT) medical examination and carry a valid medical certificate.
At the DMV, you'll take the general knowledge written test and any additional knowledge tests for endorsements you're pursuing. The CLP allows you to practice driving commercial vehicles with a licensed CDL holder in the passenger seat.
Step 3: Complete CDL Training
While not always legally required, attending an accredited CDL training school is highly recommended. Many employers won't hire drivers without formal training, and it dramatically increases your chances of passing the skills test on the first try. Training programs typically last 3-8 weeks and cover both classroom instruction and behind-the-wheel practice.
Your training should meet the Entry-Level Driver Training (ELDT) requirements that became mandatory in 2022. Make sure your school is registered with the FMCSA's Training Provider Registry.
Step 4: Schedule and Pass the CDL Skills Test
After holding your CLP for at least 14 days (requirements vary by state), you can schedule your skills test. This three-part exam includes:
- Pre-trip inspection: Demonstrating you can identify vehicle problems
- Basic vehicle control: Proving you can maneuver in tight spaces
- Road test: Showing you can safely drive in various traffic situations
You'll need to provide a vehicle that matches the CDL class you're testing for. Many training schools include the skills test as part of their program.
Step 5: Pay Fees and Receive Your CDL
Once you pass all tests, you'll pay the licensing fee (typically $50-$100, depending on your state) and have your photo taken. Your CDL should arrive by mail within 2-3 weeks, though some states issue temporary licenses immediately.
Tips for Passing CDL Written and Skills Tests
Many applicants fail their first attempt at CDL testing, but proper preparation makes all the difference. Here's how to maximize your chances of success.
Mastering the Written Knowledge Tests
The written portion covers everything from air brakes to cargo securement. Start studying at least two weeks before your test date, focusing on your state's official CDL manual available through your local DMV website.
Practice tests are your best friend here. The DMV Expert app offers comprehensive practice questions that mirror actual CDL exams, helping you identify weak areas before test day. Don't just memorize answers—understand the reasoning behind each rule.
Pay special attention to numbers: stopping distances, weight limits, and inspection requirements often trip up test-takers. Create flashcards for these specifics.
Preparing for the Pre-Trip Inspection
The pre-trip inspection intimidates many drivers, but it's simply about building a routine. You'll need to check dozens of components while explaining what you're looking for. Practice the inspection in the same order every time until it becomes automatic.
Focus on the "critical" items that automatic failures: fluid leaks, tire conditions, brake system components, and steering mechanism. Inspectors want to hear specific terms, not general observations. Saying "no cracks, breaks, or missing chunks in the tire tread" is better than "the tire looks good."
Record yourself doing practice inspections and review the footage. This helps you catch mistakes in your sequence or vocabulary.
Acing the Skills Test
During the basic control portion, take your time. Points aren't deducted for being slow—they're deducted for errors. Use all your mirrors, and don't be afraid to pull up and restart a maneuver if you're not positioned correctly.
For the road test, exaggerate your head movements when checking mirrors and blind spots. Inspectors need to see that you're aware of your surroundings. Follow the speed limit exactly, signal well in advance of turns, and maintain proper lane position.
Common failure points include rolling through stop signs, hitting curbs during turns, and improper lane changes. Practice these specific situations repeatedly.
Additional Study Resources
Your state's DMV website offers the official CDL manual, which should be your primary study material. The FMCSA website provides federal regulations that apply nationwide.

Your Path to a CDL Career Starts Now
Getting your CDL takes dedication, but thousands of drivers successfully earn their licenses every month. The key is understanding which class fits your goals, following the application steps carefully, and preparing thoroughly for each test.
Remember that your CLP is valid for 180 days in most states, giving you plenty of time to practice and build confidence before your skills test. Don't rush the process—taking time to truly master driving skills will serve you throughout your career.
