A road/skills test is required to apply for a CDL for the first time.

We do not provide vehicles. If you do not have access to a vehicle, you may wish to contact a third-party driver license examiner authorized to give the road test using their vehicle.

Third-Party Examiner: Trucks

Third-Party Examiner: Buses

The fee for a road/skills test is

• $25 for Class A or B.
• $12.50 for Class C.
• $5 for a passenger/bus endorsement (when added to an existing CDL).

CDL Knowledge (written) Tests: Upon payment of all applicable fees, you have unlimited attempts to pass the knowledge tests. For a multipart test, if you fail a section but pass another, you receive credit for the passed sections and do not have to repeat them. 

Pay a reinstatement fee of $30 ($10 for the suspension and $20 for the revocation), $10 for a limited Class D operator license; the cost of an original CDL instruction permit (A and B are $25; C is $12.50), and $10 for each endorsement.

Take all applicable CDL knowledge (written) tests.

A limited Class D operator license is issued; if the CDL written tests are passed, the appropriate class CDL instruction permit is also issued.
