Driver License Endorsements and Restrictions

Endorsements

Individuals may apply for an endorsement to be placed on their driver license. Depending on the type of endorsement, an individual may be required to provide additional information, complete a separate application, or pass a knowledge test specific to the type of endorsement the individual is seeking.

The types of endorsements an individual can apply for are listed in the chart below:

Endorsement Code
