Third Party CDL Testers

Traffic Cone



Driver License offices no longer provide the CDL skill tests. The CDL Third Party Testers Chart provides the names of organizations approved by the state to administer the CDL skill tests. This list is updated on a monthly basis. Remember, you must have a valid CDL instruction permit, with the appropriate vehicle class and endorsements, before you can take the skill tests.


The following units are not an extension of the Colorado Department of Revenue.
They are private businesses that charge a fee for their services.
This program gives you numerous options for completing your license.
