  • There is no cost to update your CDL medical certificate information. However, if you previously certified to interstate driving, and you correct your CDL driving type to intrastate only (Michigan-only driving) when your medical certificate is updated, you must apply for a corrected CDL showing the “K” restriction for intrastate driving. The cost is $18 to have the license corrected. A new photo license will be mailed to you.

  • You can certify to a different type of driving using online services.
