What you need to do to get a CDL Class A license

A Commercial Driver's License (CDL) Class A lets you drive the largest trucks and combinations — tractor-trailers, doubles, and triples. To get one, you must pass a written knowledge test, a skills test behind the wheel, and a medical exam. You also need a valid regular driver's license first. The whole process typically takes several weeks to a few months, depending on how quickly you study, schedule your tests, and find a testing location near you.

Most states require you to hold a CDL permit for at least 14 days before you can take the skills test, so you cannot rush through it in a single day. Some people go through a truck driving school, which can speed up the process and improve your chances of passing the skills test on the first attempt. Others study on their own and test independently.

Key Takeaways

  • You must hold a valid regular driver's license and pass a Department of Transportation medical exam before you can get a CDL permit.
  • The written test covers vehicle inspection, basic control, and road operation — you can study using your state's CDL manual and practice tests.
  • The skills test includes a pre-trip inspection, backing maneuvers, and a 50-mile road drive, and you must pass all three parts to get your license.
  • A truck driving school can teach you the skills and sometimes waive the written test, but costs between $3,000 and $7,000 depending on the program.
  • You can study and test on your own for less money, but you will need access to a large truck and someone to administer the skills test.

Get a medical certificate from a DOT-certified examiner

Before you can even get a CDL permit, you must pass a Department of Transportation (DOT) medical examination. This is not optional — your state will not issue a permit without proof that you passed. You need to see a Medical Examiner who is listed on the National Registry of Certified Medical Examiners, which you can search on the Federal Motor Carrier Safety Administration (FMCSA) website.

The exam checks your vision, hearing, blood pressure, and ability to operate a truck safely. You will answer questions about your medical history, including any conditions that might affect your driving. If you take certain medications or have a condition like diabetes or sleep apnea, the examiner may require additional testing or documentation. The exam costs between $75 and $150 depending on the examiner and your location.

Once you pass, the examiner issues a Medical Certificate (also called a Medical Examiner's Certificate or MEC). This certificate is valid for two years. You will need to show this certificate when you explore for your CDL permit at your state's Department of Motor Vehicles (DMV).

explore for a CDL permit at your state DMV

Take your medical certificate, valid driver's license, proof of residency, and Social Security card to your state DMV. You will fill out an process form — usually called a Commercial Driver's License process — and pay a fee. The fee varies by state but typically ranges from $20 to $100. You will also declare what class of CDL you want (Class A, B, or C) and what endorsements you need, such as Hazmat or Tanker.

The DMV will run a background check and review your driving record. If you have certain violations or convictions, you may be disqualified. Once approved, you receive a CDL Permit (also called a Commercial Learner's Permit or CLP). This permit lets you practice driving a commercial truck with a licensed CDL holder in the passenger seat, but you cannot drive commercially on your own.

Most states require you to hold the permit for at least 14 days before you can test for your license. Some states have a longer waiting period. Check your state's specific rules before you schedule your skills test.

Study for and pass the written knowledge test

Your state provides a CDL Manual (free, online or in print) that covers everything on the written test. The test has 50 questions and you must score at least 80 percent to pass. The test covers three main areas: vehicle inspection (how to check your truck before driving), basic control (how to handle the truck in parking lots and tight spaces), and road operation (how to drive safely on highways and in traffic).

You can take practice tests online through your state DMV website or through third-party sites. Many people take the test at a DMV office, though some states allow testing at approved third-party locations. The test costs between $10 and $50 depending on your state and where you test.

If you attend a truck driving school, the school may waive the written test requirement or administer it for you as part of the program. If you study on your own, you schedule the test directly with your DMV or testing location.

Complete the skills test with a certified examiner

The CDL Skills Test has three parts: pre-trip inspection, backing maneuvers, and a road drive. You must pass all three to get your license. The test takes about two hours and is administered by a state-certified examiner or a third-party testing service approved by your state.

In the pre-trip inspection, you walk around the truck and explain what you are checking and why — lights, brakes, tires, mirrors, coupling devices, and safety equipment. The examiner watches and listens to make sure you know the truck. In the backing maneuvers section, you perform specific backing exercises like straight-line backing, offset backing, and alley docking. These are the hardest part for most people because they require precise control of a large vehicle.

The road drive is a 50-mile route (or about one hour) where you drive on highways, city streets, and rural roads. The examiner watches how you handle acceleration, braking, turning, lane changes, and traffic. You must follow all traffic laws and demonstrate safe driving practices.

You can take the skills test at a truck driving school if the school is approved by your state, or you can test independently. If you test independently, you must provide your own truck and arrange for a certified examiner to administer the test. This is much harder than it sounds — you need access to a truck that meets DOT specifications, and examiners are often booked weeks in advance.

Attend truck driving school (optional but common)

A truck driving school teaches you how to operate a commercial truck, handle backing maneuvers, and pass the skills test. Most programs last 4 to 8 weeks and cost between $3,000 and $7,000. Some schools are more expensive; some are less. The cost usually includes classroom instruction, behind-the-wheel training, and the skills test administered by a school-approved examiner.

Many schools waive the written test requirement if you complete their program, which saves you time. More importantly, schools provide a truck and an instructor, so you do not have to find these on your own. Most people who attend school pass the skills test on the first attempt, while people who study independently often need multiple attempts.

Schools vary widely in quality and reputation. Some are run by trucking companies and lead to a job offer after you graduate. Others are independent and focus only on training. Before you enroll, check reviews, confirm the school is accredited by your state, and ask whether the school guarantees job placement or has partnerships with trucking companies.

Get your CDL Class A license and maintain it

Once you pass all three parts of the skills test, you return to your state DMV with your test results and your CDL permit. The DMV issues your CDL Class A license, which is valid for four or five years depending on your state. Your license will show your class (A, B, or C) and any endorsements you earned (Hazmat, Tanker, Doubles/Triples, Passenger, School Bus).

Your CDL is tied to your medical certificate. If your medical certificate expires, your CDL becomes invalid until you renew it. You must renew your medical certificate every two years. Some states require you to renew your CDL in person; others allow online renewal. Check your state DMV website for renewal important date and procedures.

If you get certain traffic violations or fail a drug test, you can lose your CDL. Violations that result in disqualification include speeding 15 miles per hour or more over the limit, reckless driving, and driving under the influence. A first disqualification is usually one year; a second is ten years.

Frequently Asked Questions

Can I get a Class A CDL without going to truck driving school?

Yes. You can study the CDL manual on your own, pass the written test at your DMV, and then take the skills test with a state-certified examiner. The challenge is finding a truck and an examiner who will test you. Most independent examiners require you to provide a truck that meets DOT specifications, and they are often booked months in advance. Many people find it faster and cheaper to attend school.

How long does it take to get a CDL Class A license?

If you attend truck driving school, the process usually takes 4 to 8 weeks from start to finish. If you study on your own, it depends on how quickly you study, how fast you can schedule the written test, and how long you wait for a skills test appointment. The minimum is about 14 days (the permit waiting period) plus however long it takes you to study and test. In practice, most independent applicants take 2 to 4 months.

What happens if I fail the skills test?

You can retake it. There is no limit on how many times you can test, but each attempt costs money and requires scheduling another appointment. Most testing locations charge $100 to $300 per skills test. If you fail, you can study more, practice with a trainer, or attend a school before you try again.

Do I need a Class A CDL to drive a pickup truck with a trailer?

No. A pickup truck with a trailer usually falls under Class B or C depending on the combined weight. A Class A CDL is required only for tractor-trailers and certain combinations of vehicles. Check your state's CDL classification rules to see what class you need for your specific vehicle.

Can I get a CDL if I have a DUI on my record?

It depends on how old the DUI is and your state's rules. Most states disqualify you if you have a DUI within the past 3 to 5 years. Some states have a permanent ban for certain violations. Contact your state DMV to find out whether your specific record disqualifies you.
