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.
