Frequently Asked Questions

You have questions? We have answers! Here is information on the most commonly asked questions regarding CDL training and testing.
What is a CDL?
A Commercial Driver License (CDL) is required for all drivers operating large commercial motor vehicles. By carrying a CDL, you prove that you have been trained and tested and that you are qualified to operate such vehicles.
What types of CDL can I get?
Applicants may qualify for three basic classes of CDL:
Class A
A Class A CDL permits the holder to operate vehicles with a weight in excess of 26,001 pounds and/or with an excess of 10,000 pounds towed.
Class B
A Class B CDL permits the holder to operate vehicles with a weight in excess of 26,001 pounds, with less than 10,000 pounds towed. A Class B also allows the holder to transport 24 passengers or more, driver included.
Class C
A Class C CDL permits the holder to operate vehicles that do not fall under Class A or B designations, such as transport vehicles carrying 16 to 23 passengers, including the driver. Class C CDL holders may also transport hazardous materials.

What do I need to apply for my Commercial Driver's Learning Permit?
When you apply for a CLP, you’ll need to bring documents that prove you’re licensed to drive, legally in the United States, and a Texas resident. TxDOT accepts quite a few documents to do this, including:
● Birth certificate
● Social Security card
● Valid U.S. Passport
● A Texas driver’s license
● An out-of-state driver’s license
● Military ID card
When you apply for your CLP, you’ll also need to bring your medical certifications, proof of insurance, and registrations for all vehicles you own. Please keep in mind that you can never have too many lessons as the more professional training you have then the safer you will become prior to going solo.
How long am I required to hold a CLP before I am permitted to take a road test?
You must hold your CLP for a minimum of 14 days before you can take the road test. This will allow you to practice your driving and prepare to get your CDL. The experienced instructors at Texas CDL Truck Services will help you understand what the test will entail and provide you with feedback on your driving during this time.
What do I need to know for my CDL test?
All CDL tests in the state of Texas consist of three basic parts:
● Vehicle Inspection (pre-trip) Test: This section tests potential CDL holders on their knowledge of vehicle safety before operation.
● Basic Vehicle Control Test: This section tests potential CDL holders on their control skills in large commercial vehicles, including forward and backward movements, turns, and other maneuvers.
● Road Test: This section tests potential CDL holders on a variety of traffic situations to ensure their ability to perform safely and efficiently during common and uncommon driving scenarios.
What are CDL endorsements?
In addition to acquiring the correct CDL license, you may be required to get certain endorsements on your license. These endorsements will allow you to transport liquids, marked hazardous materials, and passengers. They include:
● H - Allow you to transport materials labeled hazardous
● N - Permits you to transport a tanker trailer to transport liquids
● P - Permits you to drive a vehicle that is transporting passengers
● S - Permits you to drive school buses
● T - Allow you to transport two or three trailers over a specified weight
● X - Authorizes you to transport hazardous materials in a tanker trailer
Where can I get my medical certification?
Most doctors will be able to certify your medical fitness and qualification for a Texas CDL. You may not be able to get a CDL if you have any of the following conditions:
● Diabetes requiring the use of insulin to control
● Significant heart problems
● Chronic respiratory illness
● High blood pressure that cannot be controlled by medicine
● Epilepsy
● A history of substance abuse--including alcohol.
How long do I have to take my CDL test?
Your commercial learner’s permit is valid for 180 days. During that time, you’ll be able to drive a commercial vehicle under supervision so that you can practice and learn how to operate a commercial vehicle. If you do not pass your Commercial Skills test in that time, you’ll need to begin the process again.
Where can I take my CDL driving test?
The greatest benefit to taking CDL licensing training at Lamar State College Port Arthur is that you can also test at our sites. Because of a great CDL appointment backlog, LSCPA sought to gain testing certification to make things more convenient for its students, getting them to work more quickly. You can still take your CDL skills test at one of several locations throughout the state of Texas. The Texas DPS website has a complete list of locations.
