CDL Overview

A commercial driver’s license or CDL is a legal authorization that gives commercial motor vehicle (CMV) drivers permission to drive large trucks, buses, and hazardous material carriers. CDL requirements for drivers are based on the size of the vehicle and the type of cargo that they are going to deal with.

According to the Bureau of Labor Statistics, as of 2025, there are approximately 2,192,300 heavy-duty truck and tractor-trailer drivers in the US, all required to have a commercial driver’s license (CDL). This number has grown from 1,871,700 in 2016

The three CDL classes include Class A, Class B, and Class C. Each CDL class has its specific regulations and range of operations. It is very important to know the differences and the demands of each class before applying. To achieve the CDL requirements, one has to take written knowledge tests and practical evaluation of driving skills, and ensure that the drivers are competent and safety-conscious.

Class A CDL vs. Class B CDL

Class A CDL allows one to drive vehicles that have a gross combination weight rating (GCWR) of 26,001 pounds and above, provided the towed vehicle weighs over 10,000 pounds. This license is required for operating tractor-trailers and tanker trucks carrying large loads. When paired with the proper endorsements, a Class A CDL provides the greatest scope of operation in commercial driving.

Conversely, the Class B CDL permits drivers to drive a single vehicle with a gross vehicle weight rating (GVWR) of 26,001 pounds or higher, or pulling a vehicle, the weight of which is 10,000 pounds or less. A Class B CDL is required to drive heavy straight trucks, buses, and certain dump trucks.

The requirements of the training and the components of the exams are specific to each class of license. The one that you take is dependent on your career objectives. To drivers who are moving between various operational needs, knowledge of how to change a CDL from intrastate to interstate can be useful in increasing career opportunities.

The Class B CDL is commonly used in conjunction with urban operations (such as buses or dump trucks), whereas the Class A CDL offers flexibility for long-haul and heavy-freight. The selection of the appropriate type of license among your driver pool may maximize the use of your fleet and reduce downtimes.

Commercial Learner’s Permit and CDL Permit Requirements

You will need to obtain a commercial learner’s permit (CLP) before you are given your CDL. CDL permit requirements permit you to practice driving under supervision. The commercial learner’s permit application requires taking some knowledge tests of general commercial driving rules, endorsements of particular types, and types of vehicles.

According to the BLS, CLP holders must hold the permit for at least 14 days before taking the CDL skills test.

The CDL permit requirements also involve demonstration of age, medical certification, and valid identification. It must also take a minimum duration to hold a commercial learner’s permit, which is usually 14 days before you can take the CDL skills test, and one of the important aspects of CDL permit requirements.

“A Midwest fleet manager explained that covering CLP costs for new recruits cut turnover by 40% in the first year, as drivers felt invested and stayed loyal.”

Future commercial drivers are expected to realize that they must be properly documented and compliant. Commercial drivers: Multi-drivers Fleet operators can gain insight into what an ELD system is and its implications on the commercial driving operation.

In the case of fleets, the cost of CLPs of recruits is a good retention strategy. Drivers that are trained and licensed under company sponsorship are more likely to remain loyal, reducing turnover and saving your investment.

Steps to Apply for a CDL

The process of getting CDL is a formal one that begins with the establishment of the fact that you are in compliance with all the requirements of the CDL, such as being 18 years old (or 21 years old in the case of interstate driving) and being medically fit to drive heavy vehicles.

The second step is to apply for the commercial learner permit by taking the required written exams at your state DMV. Drive with your permit under supervision to develop skills before the final skills test.

Lastly, complete and pass the practical driving examination, which is a test that determines your capability to check vehicles, operate the truck or the bus, and drive safely on the roads. Once you pass, you are given your full commercial driver’s license.

The application process will start with the collection of the necessary documentation that usually consists of evidence of identity, Social Security number, legal presence in the United States, and state of residence. Other states have other requirements or expedited processing of some applicants.

The CDL application process includes background checks as a regular part. This involves checking your driving history of violations, accidents, or license suspension that could make you ineligible to drive commercially. Knowing what is considered a disqualifying offense may assist the applicants in resolving the problems at an early stage, or know when they should wait before they can apply.

The written knowledge tests are state-specific, but usually include federal regulations, vehicle operation principles, safety procedures, and areas of endorsement. Computerized testing with immediate results is provided in many states, and in others, it may require scheduled appointments or provide paper-based alternatives.

It is also important to prepare finances before getting CDL, because CDL licensing has several fees, such as permit applications, testing fees, the cost of license issuance, and even the cost of the training program. Knowing the total cost in advance will enable the applicants to plan their budget and prevent wastage of time because of a lack of funds.

The scheduling process of the skills test may take a lot of time, depending on the location, with some areas having a longer wait than others. The licensing process can be hastened by planning in advance and being flexible with testing dates and locations, which will get you on the road sooner.

Getting a CDL depends very much on the skills test, practice, and preparation between obtaining the permit and taking the test. This is not just driving practice but also learning how to inspect the vehicle prior to the trip, learning about the vehicle systems, and gaining the confidence to act in the conditions of examination. Knowledge of truck preventive maintenance is useful in making sure that vehicles are in good condition and that they are roadworthy.

On the fleet level, this process can be streamlined with the help of HR and compliance teams to minimize the delays during onboarding. A large number of carriers incorporate CDL application support into driver recruitment as a way of accelerating time-to-road and minimizing expensive downtime.

CDL Training Requirements

The knowledge and skills required to operate commercial vehicles safely can only be developed by complying with CDL training requirements. CDL training requirements for the majority of states have set a prerequisite of having a certified CDL training program before the CDL exam.

Training programs will normally incorporate classroom training on safety rules, vehicle inspection, transport laws, and on-the-job training on driving using commercial trucks or buses. The successful completion of a full-course CDL training can be used to guarantee the preparation to take the written and practical exams.

According to CDS, while CDL training costs range from $3,000 to $7,000 for comprehensive programs in 2025, many drivers recoup this investment within their first 3 to 6 months through higher pay and bonuses. For example, the National Transportation Institute reports that first-year earnings for new CDL drivers can increase by $20,000 to $30,000 compared to non-commercial driving jobs, making CDL training a valuable career investment.

Proper preparation, such as knowledge of fleet safety procedures, is important to career-oriented drivers as well as for CDL training requirements. Get acquainted with the preparation for commercial fleet inspections to guarantee the lack of violations.

In the case of fleets, ROI is even greater: According to the National Transportation Institute, carriers save $15,000+ per driver in lower recruiting expenses when they invest in training their own employees rather than hiring new ones. Training also makes sure that drivers are conversant with your fleet TMS, ELDs, and safety systems on the first day.

“A Southeast trucking company found that in-house CDL training not only reduced recruiting costs but also improved safety scores by 18% within a year, thanks to drivers being trained on the fleet’s own safety systems from day one.”
