CDL Testing

To obtain a CDL, applicants are required to complete a series of knowledge tests, a vision screening, and a driving skills test.
Knowledge Tests: All written tests are multiple choice. The passing score for a written test is 80 percent. The applicant is only required to retake the test they failed. Written tests that are passed are valid for two years. A written test is required in a number of situations including when:
  • An applicant has never been previously licensed in the United States, any U.S. Territory, Canadian Province, or Germany; 
  • A client’s driving record indicates that his last license has been expired, revoked or denied for two years or longer (immediately prior to this application), or his privilege to drive has been revoked, canceled or disqualified;
  • The applicant is upgrading the class of his license or adding any endorsements;
  • An applicant is removing the air brake restriction “L;” and the applicant is removing the Air Over Hydraulics restriction (He must perform the pre-trip and road test as well).
An applicant who possesses a CDL license with a hazmat endorsement “H” will be required to take the hazardous materials test upon transferring their out-of-state CDL license. Clients with Wyoming CDLs will be required to retake the hazmat test if “test score tracking” does not indicate that test has been passed within the previous two years.
Vision Screening: A vision reading of 20/40 with both eyes is required to pass the vision screening. If you fail to meet this standard with or without glasses, you may be required to obtain a vision statement from your eye specialist. If you wear contact lenses or glasses during the vision screening, you will be required to wear them at all times while driving. A vision reading of worse than 20/40 (best possible correction) in one eye will result in the CDL driver being restricted to intrastate driving only.
Skills Test: A skills test will consist of a vehicle pre-trip inspection, a basic control skills test and an over-the-road skills test. Skills tests are conducted by appointment only after the successful completion of all applicable written tests. The State of Wyoming does not furnish vehicles for the skills testing process. Vehicles for testing must be driven to the test site by a person who holds a valid driver’s license for the class and type of vehicle used for testing.
Applicants are required to furnish vehicles for their skills test that are representative of the class of license for which they are applying. If the vehicle or combination vehicle is a tank vehicle you MUST have an N endorsement on your CLP. If the tank vehicle previously contained hazardous materials you MUST have a letter in-hand stating the tank vehicle has been purged of all residue. However skills tests will not be conducted in a loaded commercial vehicle. Simulated weight is the only thing allowed in trailer. Additionally, placarded vehicles are not allowed to be used for skills testing.
The skills test fee is $85. For more information, select scheduling in the navigation column above. 
Wyoming third-party examiners are allowed to administer the skills test only to their employees and not to the general public. Third-party examiners are not allowed to charge a fee for the administration of the skills test. The training and certification process for third-party examiners is provided by WYDOT at no charge.
Applicants for a Wyoming CDL, who hold a valid US Military license, must pass all written tests for the class of license they currently hold.

Adding or Changing Class Codes or Endorsements

You are required to appear in person at your local exam office to complete any testing associated with adding an endorsement or upgrading your class of driver's license.  

If you are out-of-state and want to add the Motorcycle class code to your current Wyoming driver's license, you must submit certification from an authorized Motorcycle Safety Education class, complete the application form and pay the renewal fee.
