Yes . . . You will have to pass written exams and skills exams. Just how many exams you will have to take and pass will depend upon the type(s) of commercial vehicles you will be driving and what type of "cargo" you will be transporting.


The "written" exams consist of the knowledge portion of your Utah CDL exams. There are seven different written exams. Which ones you will be required to take and pass depends upon the type of commercial vehicle that you will be driving. A description of these written exams follows . . .

  • General Knowledge Test . . . Must be taken and passed by ALL CDL applicants no matter what Class of CDL or Type of Endorsement(s) are needed. You WILL take this written test. You WILL pass this written test if you are to obtain a CDL.
  • Air Brakes Test . . . Must be taken and passed if any vehicle you drive has air brakes.
  • Combination Vehicles Test . . . Must be taken and passed if you drive combination vehicles requiring a Class "A" CDL.
  • Passenger Transport (P) Test . . . Must be taken and passed by all bus driver applicants. An additional written test may be required if transporting children to and from school.
  • Hazardous Materials (H) Test . . . Must be taken and passed if you transport hazardous materials requiring "placarding".
  • Tank Vehicles (N) Test . . . Must be taken and passed if you drive a "tank" with a capacity of more than 1000 gallons.
  • Doubles & Triples (T) Test . . . Must be taken and passed if you pull double or triple trailers.

The "skills" exams consist of the practical portion of your Utah CDL exams. They consist of three parts as follows . . .

  • Pre-Trip Vehicle Inspection Test . . . You will be tested to see if you know whether your vehicle is safe to drive. The examiner will score each item that you correctly inspect and explain.
  • Basic Vehicle Control Test . . . You will be tested on your basic skills in controlling the vehicle . . . including moving your vehicle forward, backward, and turning within a defined area. You will be scored on how well you stay within the exercise boundaries and how many pull-ups you make.
  • On-Road Test . . . You will be tested on your skill to safely drive your vehicle in a variety of traffic situations.

The skills exams are taken in the same "type" vehicle that you will be licensed in.


You can apply for your CDL. You must provide proof that you possess a valid DOT medical certificate (you will need to get a physical in accordance with MCSR 49 CFR 391.41. . . . the medical forms are included with the CDL Course package), fill out the forms, provide documentation, and pay the appropriate fees.

Utah CDL (commercial driver's license) Fees
  • Utah CDL Duplicate $18.00
  • Utah CDL Renewal $40.00
  • Each Utah CDL Endorsement is $7.00 (school bus/passenger and tanker/hazmat can be combined for a single $7.00 fee.) If you have the motorcycle endorsement, it is $9.50 to renew

Getting your original Utah CDL
Once you have obtained a DOT card you will want to research which class of Utah CDL you need, and if there are any endorsements needed. Then to prepare for the written test study the Utah CDL Handbook.
  • Visit one of the Utah driver license offices - however, Farmington, Heber, Kanab, Logan, Provo and Tooele offices do not process Utah CDL's at this time;
  • Complete the Utah driver license application in the office, or you can complete the online application and bring with you to your visit;
  • Photo will be taken;
  • Provide proof of citizenship, full social security number and Utah residence. Visit our required documentation page for what is acceptable proof;
  • Pass the eye test;
  • Take the Utah CDL written test (based on endorsements needed);
  • Pay the applicable fee of $40.00 plus each Utah CDL endorsement is $7.00 (school bus/passenger and tanker/hazmat can be combined for a single $7.00 fee.) If you currently have the motorcycle endorsement on your regular license you will need to pay the additional $9.50 motorcycle endorsement because your license/endorsement will extend for another 5 years (example - class A Utah CDL with doubles and triples, tanker, hazmat and motorcycle would be $63.50 - 40 + 7 + 7 + 9.50 = 63.50);
  • When the written test is passed you will be issued a Utah Commercial Learner Permit (CLP);
  • Complete your Utah CDL training with your company, or one of the third party testers throughout the state; and
  • Perform a skills test in appropriate vehicle for the class of Utah CDL you are applying for. You can complete your skills test by a third party tester, or by a driver license examiner. An appointment is required if taking your skills test at the Driver License office you first applied at. Once you have passed all your testing, return to the same office you started the process and an examiner will confirm your test scores and issue you a temporary Utah CDL.
Military Personnel - you may qualify for a waiver of the Utah CDL skills testing. Please see our military skills test waiver page for more information.

You can renew up to 6 months prior to your driver license expiring.

If you are planning to be out of the State of Utah for longer than 6 months prior to your license expiring, you can provide documentation to the Utah Driver License Division before the renewal time period. If you are an active duty military service member, your license will expire 90 days after discharge. Make sure to bring discharge documentation with you when you renew your Utah CDL.

As of January 2010, you were required to provide proof of your citizenship and social security card. As part of this process, the Driver License Division has scanned the necessary documentation. To obtain a duplicate or renewal Utah CDL you only need to bring your DOT card and appear at one of our driver license offices, fill out an application, take your picture, pay the fee and you're good to go.

To make it easier, here are the links to some of the documents your will need to make your process go a little smoother.

Utah CDL Changes (Effective July 1, 2015)

The Division will no longer issue Utah CDL learner permits or 60 day licenses to out of state residents.
  • Drivers coming to Utah for CDL training will need to have a CDL learner permit issued by their home jurisdiction.
  • Drivers that were issued a CDL learner permit with a non-resident status prior to July 1, 2015 must complete the license process by June 30, 2015 or they will not be able to complete the process.
  • Until close of business on June 30, 2015 the Division will continue to issue Utah CDL learner permits to out of state residents but we will not be able to issue a license following any testing they complete.

The Division may test and accept CDL skills tests from any state in the U.S.
  • All CDL learner permit holders must hold the permit for 14 days prior to taking a skills test.
  • If a driver upgrades their permit during at any time for an endorsement that requires a skills test the 14 day waiting period starts over.
    • Example: Applicant is issued a Class B permit with no endorsements. Applicant returns at a later date and adds a passenger and school bus endorsements. The new permit will be issued for an additional 180 days and the driver 14 waiting period starts over.
  • If the change to the permit does not require an additional skills test then the 14 days does not start over.
