How can I change my certification?
To change your certification category, please visit a driver’s license issuance site to complete a new certification form.

Drivers that certify to intrastate driving are required to have a restriction placed on their license (“K” restriction). Changing your certification category may require the addition or the removal of this restriction on your driver’s license.
