CDL Testing
To obtain a CDL, applicants are required to complete a series of knowledge tests, a vision screening, and a driving skills test.
Vision Screening: Commercial drivers require a vision reading of 20/40 (with or without lenses) in each eye and a horizontal vision reading of 70 degrees in each eye from an examiner, optometrist, or opthamologist to pass the vision screening. 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 or a horizontal reading of less than 70 degrees in one eye will result in the CDL driver being restricted to intrastate driving only or will require additional screening as outlined by FMCSA to drive in interstate commerce. Additional information can be found on the
FMCSA website.
Entry Level Driver Training: The Entry Level Driver Training (ELDT) regulations set uniform training standards for entry level drivers seeking to obtain certain commercial driver licenses (CDLs) and CDL endorsements, as established in
49 CFR part 383 subpart F.
Entry level drivers include those applying to:
- Obtain a Class A or Class B CDL for the first time;
- Upgrade an existing Class B CDL to a Class A CDL; or
- Obtain a School Bus (S), Passenger (P), or Hazardous Materials (H) endorsement for the first time.
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 are valid for the term of the CLP. A written test is required in a number of situations including when:
- An applicant has never been previously licensed in the United States or any U.S. Territory;
- 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revoked or denied for two years or longer (immediately prior to this application), or his privilege to drive has been revoked, canceled or disqualified;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 (Pre-trip and road test must also be completed).
An applicant who is applying for a CDL with a Hazmat endorsement (H) for the first time will be required to complete the ELDT Hazmat training before attempting the Hazmat knowledge test.
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 knowledge test if the driver history record does not indicate that test has been passed within the previous two years.
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.
WYDOT locations for CDL Skills Tests are Casper, Cheyenne, Cody, Evanston, Gillette, Rawlins, Riverton, Rock Springs, Sheridan, and seasonally in Afton.
Wyoming third party examiners are only allowed to administer the skills test to their employees, volunteers, or students. 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. If you are interested in becoming a Wyoming third party organization please contact us at cdl@wyo.gov.
After February 7, 2022, CDL skills tests may only be administered to those individuals who have completed ELDT training or have received a grandfather exemption.
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, and may not be required to complete ELDT training.
