Testing for a CDL

Commercial Driver License (CDL) testing is mandated by the Federal Motor Carrier Safety Administration (FMCSA) and is regulated by that agency. 

Wyoming's Q-test automated testing system provides the opportunity for you to take the written test on a touch-sensitive computer. This system allows for individuals with reading difficulties to hear each question orally, as well. If you need to listen to the questions when you are testing, you must advise the examiner prior to taking the test. Testing is available in English only.

Required written tests:

Class "A"
  • General Knowledge
  • Combination Vehicle
  • Air Brakes (if vehicle has them) 
Class "B"
  • General Knowledge
  • Air Brakes (if vehicle has them)
Class "C"
  • General Knowledge
  • Hazardous Materials (for "H" endorsement) and/or 
  • Passenger (for "P" endorsement)

Endorsements:  You must take a written test for each endorsement you need to operate your commercial vehicle. Endorsements also requiring a driving skills test are denoted with an * below:   

"H"  - Hazmat

Authorizes a driver, 18 years of age or older, to operate a vehicle transporting hazardous materials. It can be added to Class "A", "B" and "C" commercial license only. If you are between the ages of 18 to 20 years you will be restricted to "Intrastate Driving Only." You must also complete and pass the Federal Hazardous Materials Security Threat Assessment and be fingerprinted. This endorsement cannot be added to a non-commercial driver's license.  Please go to the TSA Web site for locations and information concerning the assessment and fingerprinting.

If you are transferring a CDL with a hazmat endorsement issued in another state, you are required to complete the Federal Hazardous Materials Security Threat Assessment and be re-fingerprinted.  You are also required to retake the written test for Hazardous Materials.
