CDL Online Training FAQs
How does online ELDT work?
Many people ask us how to become a truck driver. CDL2Go makes it easy! After you purchase the theory training you’re looking for, you will be sent a confirmation email that will include your login details. You will be able to login and view your course(s) at any time by visiting cdl2go.com.
Once you complete the courses, you will complete a submission where your data will be placed into the FMCSA, or federal system as being ELDT knowledge test trained.
Is CDL2Go registered on the FMCSA’s Training Provider Registry?
Yes, we are! At CDL2Go, we’ve been preparing for the new ELDT laws to take effect since 2018, and have centered our curriculum around the written tests that you will need to pass at your state’s licensing department.
Can I complete ELDT online?
Yes. ELDT theory can be completed online through an approved provider when the course matches your CDL class, upgrade, or endorsement need. Hands-on training and skills testing are separate.
Who needs ELDT theory?
ELDT theory generally applies to first-time Class A or Class B CDL applicants, Class B drivers upgrading to Class A, and drivers adding HazMat, Passenger, or School Bus endorsements.
What happens after I complete ELDT theory?
After you complete ELDT theory, the next step depends on your CDL goal. You may need to continue with local hands-on training, testing, state licensing steps, or endorsement-specific requirements.
What happens after CDL2GO submits my ELDT completion?
After CDL2GO submits eligible ELDT completion information, you should follow the next instructions from your state licensing agency, training provider, or testing location. Keep any completion records available for your own reference.
Is ELDT the same as Permit Prep?
No. Permit Prep helps you study and practice for CDL knowledge testing. ELDT theory is a required training step for certain CDL classes, upgrades, and endorsements.
Does CDL2GO provide behind-the-wheel training?
No. CDL2GO supports online theory, permit preparation, and training guidance. Behind-the-wheel training and skills testing are separate and must be completed through the appropriate local training or testing process.
Do I need ELDT training?
Yes, If you are:
Anyone who was issued a CDL or an S (school bus), P (passenger), or H (hazardous materials) endorsement prior to February 7, 2022 is not required to complete ELDT for their respective CDL or endorsement. Any applicant who acquired their commercial learner’s permit (CLP) prior to February 7, 2022, and obtains a CDL before the CLP or renewed CLP expires, is not subject to the ELDT requirements. Any individual who meets one of the exceptions for taking a skills test in 49 CFR Part 383 is also exempt from the ELDT requirements.
How long does it take to complete a course?
The beauty of taking an online course is the ability to go at your own pace. Some people finish their course in a day, while others may take a week or two. You will have 180 days to complete your course from the date of purchase, but if you are unable to complete your course within 6 months, you may reach out to us about an extension.
What does ELDT mean for CDL training?
In February of 2022, new ELDT regulations set by the Federal Motor Carrier Safety Administration (FMCSA) went into effect. This new mandate is a set of minimum requirements for entry-level drivers who are obtaining a CDL for the first time, or upgrading an existing CDL. These regulations are set at the federal level, and all CDL drivers (existing and potential) and training providers must abide by them. Even though it seems like more hurdles to jump, these standards were designed to make our highways safer. Further preparation and training for CDL drivers means less accidents on the road.
Where can I complete my Behind-The-Wheel training?
We work directly with many Behind-The-Wheel training companies. We can help you find the right option to fit your needs. Contact us for more information!
Where should I start with CDL2GO?
Start with CDL Preparation if you are not sure what comes first. It gives you a clear place to understand the early CDL process, written-test preparation, online theory, and how Class A, Class B, B-to-A, and endorsements may fit your goal. After that, you can choose the page that matches what you are trying to do next without sorting through everything at once.
How do I know whether I need Class A or Class B?
If you already know the type of commercial vehicle or job you are aiming for, begin by comparing Class A and Class B. If you are still learning the basics, start with CDL Preparation first. It gives you a calmer overview of written-test preparation, license choices, and what usually comes before behind-the-wheel training so your next step makes more sense.
Is CDL2GO the same as a truck driving school?
No. CDL2GO is not a traditional truck driving school. CDL2GO helps with CDL preparation, online theory, license-type understanding, and endorsement guidance so you can make better sense of the process before or alongside hands-on training. Behind-the-wheel instruction, skills testing, and licensing decisions are handled by the appropriate training providers and licensing authorities. CDL2GO helps make the starting point clearer before you move forward.
What should I understand before starting CDL training?
Before starting CDL training, it helps to understand which CDL class may fit your goal, what the written-test or permit-prep step involves, and how theory, range, and public roads fit together. You do not need every detail at once. CDL2GO helps you review the first pieces clearly, then move toward Class A, Class B, B-to-A, endorsements, or online theory with less guesswork.
Can I use CDL2GO before choosing Class A or Class B?
Yes. CDL2GO can be useful before you choose Class A or Class B. You can review CDL basics, permit-prep topics, online theory context, and the difference between the main license types before committing to a specific direction. That early review can make the Class A and Class B choices feel less abstract and help you move forward with better timing.
What is the difference between CDL preparation and CDL training?
CDL preparation helps you understand the process, review written-test topics, and get oriented before hands-on training begins. CDL training can include instruction connected to your license type and behind-the-wheel stages such as range and public-road driving. CDL2GO helps clarify the preparation, class selection, and online learning side so you can better understand what you need before practical training begins with better context.
What should I review before starting CDL training?
If you are choosing between Class A, Class B, B-to-A, or endorsements, start with CDL guidance. If you are reviewing for the written test or trying to understand what comes first, start with CDL Preparation. If your question is about an account, course access, payment, or a specific support issue, use the contact page so the right team can help.
What should a new CDL learner review first?
A new CDL learner should first review the basic CDL process, permit-prep expectations, and the difference between Class A and Class B. After that, it is easier to understand where online theory, endorsements, and behind-the-wheel training fit. The goal is not to study everything immediately. The first step is getting enough direction to choose the next page with better context.
What is the difference between Class A CDL and Class B CDL?
Class A and Class B are different CDL license types, not just different course names. Class A is generally connected to combination vehicles such as tractor-trailers. Class B is usually more focused on straight trucks, buses, and certain local-use commercial vehicles. Start with this comparison for quick orientation, then review the Class A and Class B pages before choosing your next step.
Do I need a Class A CDL for the vehicles I want to drive?
Class A may be a better fit if your goal involves tractor-trailers, combination vehicles, or broader commercial driving opportunities. You do not need to decide everything from one short answer, but those goals are strong signs that Class A deserves a closer look. Review the Class A page for a clearer explanation of what that license type usually involves and what to consider next.
Is Class B enough for what I want to drive?
Class B may be a better fit if your goal involves straight trucks, certain local commercial vehicles, buses, or work that does not require a tractor-trailer or broader Class A combination-vehicle setup. Use this as a starting point only. The Class B page explains the details, with Class A available for comparison if your goals are broader or may change later.
Is B-to-A the same as starting Class A from the beginning?
No. B-to-A is not the same as starting Class A from the beginning. It is for someone who already has a Class B background or Class B training experience and wants to understand what changes when moving toward Class A. Keep that difference in mind, then review the B-to-A page for the upgrade-specific explanation, comparison, and next-step context before planning.
Can I compare Class A and Class B before starting preparation?
Yes. Comparing Class A and Class B before starting preparation can help you avoid studying in the wrong direction. You do not need to know every training detail yet, but it helps to understand which license type is most relevant to your driving goal. Start with the comparison, then review the Class A and Class B pages before choosing preparation steps.
Do I need a CDL class before I add endorsements?
Your CDL class and endorsements work together. Understanding whether you need a Class A or Class B CDL first can make it easier to determine which endorsements may apply to your goals. Endorsements can add permissions or special knowledge for areas such as Hazmat, Passenger, School Bus, Tanker, or Doubles / Triples. Start with the license type, then review endorsements once your goal is clearer.
Should I choose Class A or Class B before choosing endorsements?
In most cases, yes. It helps to understand whether Class A or Class B fits your goal before choosing endorsements. Your CDL class gives the endorsement decision context. Passenger, School Bus, Hazmat, Tanker, and Doubles / Triples do not replace the CDL class; they add to it. A clear license choice first makes endorsement decisions easier to understand and compare later.
Can a Class B driver later move toward Class A?
Yes. A Class B driver may later review the B-to-A path if their vehicle needs, job goals, or long-term CDL plans begin pointing toward Class A. That does not make Class B the wrong starting point. It simply means the next step may involve upgrading. Review B-to-A for the upgrade explanation, with Class A available for the broader license overview.
Do I need a Class A or Class B CDL with my endorsement?
Yes, a Class A or Class B CDL is required with an endorsement. Becoming a truck driver is an easy solution; however, which courses you need might be a little more difficult. Depending on what endorsement you’re looking for, we have course packages that pair the endorsements you need with the respective license.
What are CDL endorsements?
CDL endorsements are added qualifications that may be needed for certain vehicles, cargo, passengers, or driving situations. They do not replace Class A or Class B. For example, Hazmat relates to hazardous materials, Passenger and School Bus relate to carrying people, Tanker relates to liquid cargo, and Doubles / Triples relates to certain trailer combinations. Start with the Endorsements Hub before choosing a specific endorsement page.
Do I need Class A or Class B before getting endorsements?
Endorsements usually build on a CDL class instead of replacing it. Class A or Class B helps define the kind of commercial vehicle you are preparing for, and endorsements add special permissions or knowledge based on the vehicle, passengers, cargo, or trailer setup involved. If you are unsure which endorsement applies, use the Endorsements Hub first, then review the specific endorsement that matches your goal.
Which CDL endorsement should I get first?
Start with the endorsement most connected to your driving goal. If the goal involves hazardous materials, review Hazmat. If it involves carrying people, review Passenger and then School Bus if the school-specific path applies. If your question is about liquid cargo or certain trailer combinations, review Tanker or Doubles / Triples. When you are unsure, start with the Endorsements Hub for a clearer comparison.
How are CDL endorsements different from each other?
CDL endorsements are different because they apply to different driving situations. Hazmat involves hazardous materials. Passenger and School Bus involve carrying people, with School Bus being more specific. Tanker focuses on liquid cargo, while Doubles / Triples focuses on certain trailer combinations. Use the Endorsements Hub to see how they differ before opening the page for the endorsement that matches your goal.
Why is Hazmat treated differently from other endorsements?
Hazmat is treated differently because it usually involves more responsibility, preparation, and approval-related steps than many other endorsements. That does not mean every Hazmat question needs a long requirements explanation, but it does mean Hazmat deserves a careful review. Review the Hazmat page when you need to understand what the endorsement is for, where it fits, and what to consider next.
How is Passenger different from School Bus?
Passenger is the broader endorsement connected to carrying people. School Bus is more specific because it applies to school transportation. They are related, but they are not the same. Passenger helps explain the wider people-moving requirement, while School Bus adds a more specific setting and purpose. Start with the Endorsements Hub or Passenger page, then review School Bus if that specific path applies.
Is Tanker the same as Hazmat?
No. Tanker and Hazmat are different endorsements. Tanker is mainly about liquid cargo and how that cargo can affect vehicle handling. Hazmat is connected to hazardous materials and may involve additional responsibility and approval-related steps. They can sometimes appear near each other in planning, but they are not the same endorsement. Use the Endorsements Hub for comparison, then review Tanker or Hazmat based on your goal.
Do endorsements replace CDL training?
No. Endorsements do not replace CDL training, Class A, Class B, or a B-to-A upgrade. They add special permissions, responsibilities, or knowledge after you understand the CDL class that fits your goal. Start with the license type or training path that makes sense for you, then use the Endorsements Hub to review which endorsements may apply before choosing a specific endorsement page.
How do I compare endorsement options?
Compare endorsements by asking what each one adds to your CDL goal. Hazmat relates to hazardous materials. Passenger and School Bus relate to carrying people, with School Bus being more specific. Tanker focuses on liquid cargo, while Doubles / Triples focuses on certain trailer combinations. Use the Endorsements Hub to compare options, then move into the specific page that fits your driving goal.
Where should I go if I do not know which endorsement applies?
If you do not know which endorsement applies, start with the Endorsements Hub rather than guessing. It helps you compare Hazmat, Passenger, School Bus, Tanker, and Doubles / Triples in plain language. From there, move to a specific endorsement page only when that endorsement clearly matches your vehicle type, cargo, passengers, driving goal, or next CDL step for your plan and training needs.
