CDL FAQ
Semi Truck Driving School & CDL Trainers info
What is a commercial driver license (CDL)?
Semi Truck Driving or Operating large commercial motor vehicles requires specialized skills and CDL trainers that will teach what must be learned. A CDL is a professional license permitting the holder of the license to drive those large commercial vehicles and buses on public roadways in Texas and in the United States. This license demonstrates that you have been trained, tested, and are qualified to safely operate large commercial motor vehicles.
What types of CDLs are there?
To obtain a CDL, it will be necessary for you to determine which class you will need. There are three basic classes of CDLs:
What are Endorsements?
Depending upon what you will be transporting, you may need one or more of the following six endorsements. An endorsement allows you to operate certain types of commercial motor vehicles and transport specific items. There is additional testing required to obtain an endorsement and in some cases, if you already have a CDL you will be required to hold a commercial learner permit for that endorsement for at least 14 days before being able to add it to your CDL.
What is the difference between Interstate and Intrastate?
When applying for a CDL it will be necessary for you to understand what type of commerce you will be operating in so that the correct type of license can be issued to you. You may apply for a CDL that allows for the transportation of either interstate and/or intrastate commerce. If you apply for an interstate commerce CDL, it will allow you to operate in both interstate and intrastate commerce, unless you apply for an interstate CDL specifically to operate within a certain capacity.
The definition of interstate and intrastate commerce are provided below to assist you in determining what type of commerce you will be operating in and the appropriate form you will need to certify to when applying for your CDL. You may only certify to one form and one section.
Interstate Commerce
Is trade, traffic or transportation:
To be able to operate in Interstate Commerce, you must be able to certify that you meet the requirements provided on either the Interstate Driver Certification form (CDL-4), or the Certification of Physical Exemption form (CDL-10).
Intrastate Commerce
To be able to operate in Intrastate Commerce, you must be able to certify that you meet the requirements in only one of the Sections on the Intrastate Driver Certification form (CDL-5).
The Bill of Lading will be an indicator as to whether a shipment or commodity is interstate or intrastate. If there is not a Bill of Lading then the origin and destination of the shipment will be an indicator.
Medical Certification Requirements
Once you have determined which form you will be certifying to, review the instructions on the form very carefully to determine if you need to provide and maintain a current medical examiner's certificate with the Department.
Will I need to apply for a Commercial Driver License Permit (CLP) before getting my CDL?

Interstate Commerce
Is trade, traffic or transportation:

The Bill of Lading will be an indicator as to whether a shipment or commodity is interstate or intrastate. If there is not a Bill of Lading then the origin and destination of the shipment will be an indicator.
Medical Certification Requirements
Once you have determined which form you will be certifying to, review the instructions on the form very carefully to determine if you need to provide and maintain a current medical examiner's certificate with the Department.
