DO I HAVE TO PASS ANY EXAMS TO GET A WYOMING CDL?

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.

WHAT ARE THE WYOMING CDL WRITTEN EXAMS?

The "written" exams consist of the knowledge portion of your Wyoming 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.

  • Doubles & Triples (T) Test . . . Must be taken and passed if you pull double or triple trailers.
WHAT ARE THE WYOMING CDL SKILLS EXAMS?

The "skills" exams consist of the practical portion of your Wyoming 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.

AFTER I PASS ALL OF MY CDL EXAMS . . . THEN WHAT?

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.

Wyoming CDL Testing

To obtain a Wyoming CDL, applicants are required to complete a series of written knowledge tests, a vision screening, and a driving skills test.

Wyoming CDL Written 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. Wyoming CDL written tests that are passed are valid for two years. A written test is required in a number of situations including when:
  • A Wyoming CDL 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 Wyoming CDL applicant is upgrading the class of his license or adding any endorsements;
  • A Wyoming CDL 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).
A Wyoming CDL 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.

Wyoming CDL 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.

Wyoming CDL 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 Wyoming CDL 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 fee for a Wyoming CDL skills test is $40. Click here for information on scheduling CDL testing.

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.
