About the Texas CDL Permit Test

All of the information on the Texas CDL knowledge exam come from the official CDL handbook. 

You can find the official copy from the Texas DPS here: Download Texas CDL Manual

The knowledge tests you’ll need to take and pass depend on the Class of CDL you are applying for and the endorsements you plan to get. 

At the very least, all CDL applicants in Texas will need to pass the CDL general knowledge exam, which is based on Sections 1 through Section 3 in the CDL manual. 

You’ll be tested on questions about:

  • General Trucking Knowledge.
  • Driving a Commercial Vehicle Safely.
  • Transporting Cargo Safely.

How many questions are on the CDL test in Texas?

Here’s what you need to know about the Texas CDL general knowledge exam:

  • There are a total of 50 questions.
  • There is a time limit of 60 minutes to take the test. 
  • You must get a score of 80% or 40 correct answers to pass.

The Texas CDL tests you’ll need to take depend on whether you’re applying for a Class A, Class B, or Class C CDL and which CDL endorsements you wish to apply for.

How Hard is the CDL test in Texas?

The CDL general knowledge test and CDL endorsement tests are a lot harder than the knowledge tests for your standard Texas driver’s license.

If you don’t take the time to study and prepare, you will likely fail.

However, if you spend the time reading through and understanding the Texas CDL handbook and taking practice tests, your chances of passing will be much higher.

Which CDL tests do you need to pass in Texas?

The CDL knowledge tests you need to take in Texas depend on which Class of CDL you’re applying for and which endorsements you need. The CDL written tests you may need to take include:

If you plan on taking multiple CDL knowledge and endorsement tests on the same day, you should plan to give yourself at least 2 to 3 hours to take the tests.

  • Safe operation of different types of commercial motor vehicles (CMV).
  • Texas CDL license requirements.
  • Medical Certificate requirements.

How to Get a Texas Commercial Driver License (CDL)

As a CDL holder, you’ll be eligible to operate large commercial vehicles that require specialized skills, training, and education.

In order to get your CDL, you’ll need to comply with the requirements set by the Texas DPS and the Federal Motor Carrier Safety Administration (FMCSA).

To be eligible for a commercial driver’s license in Texas, you must:

  • Be a Texas resident. 
  • Be at least 18 years old to drive within Texas.
  • Be at least 21 years old to drive interstate. 
  • Already hold a valid, noncommercial Texas driver’s license.

As part of your application, you’ll need to submit:

  • A completed application for a CDL.
  • Proof of your age and identity. 
  • Proof of your Social Security Number. 
  • Proof of your residency in the state. 
  • Certified medical examination documents and paperwork. 
  • Any necessary background checks. 
  • Payment for your Commercial Learner’s Permit and Testing Fees.

The first step towards getting your commercial driver’s license is your Texas Commercial Learner’s Permit (CLP). To get the CLP you’ll need to:

  • Visit the DMV.
  • Submit your application, identification, residency, and medical documents, and pay the necessary fees.
  • Pass a vision test.
  • Pass the CDL general knowledge test and any necessary written tests for endorsements you’ll be applying for. 

After you pass the tests, you’ll receive your Texas commercial learner’s permit.

With your learner’s permit, you’ll be able to practice driving a commercial vehicle with a supervising instructor and prepare for your road test. 

You’ll be eligible to take your CDL skills test after you’ve held the CLP for at least 14 days. 

You will either take your skills test through the DMV or an authorized testing facility. You’ll need to take and pass the test in the type of commercial vehicle that corresponds with your CDL Class and any endorsements. 

Fees for your Texas CDL may include:

  • $97 for applicants 18 to 84 years old, valid for 5 years.
  • $26 for applicants 85 years old and older, valid for 2 years.
