Secretary of State
Commercial drivers who must renew their CDL, certification, or commercial plate (GVW) are advised to make an appointment to renew their credential(s) at a Secretary of State branch.
Licensed CDL drivers can submit their valid medical certificate to update their credential at Michigan.gov/CDL.
Additionally, the federal government has extended the deadline for submitting medical certificates expiring on or after Dec. 1, 2020, to May 31, 2021.
The waiver doesn't apply to CDL drivers whose medical certificates expired between March 1, and Nov. 30, 2020. Those who have not yet done so risk having their privileges downgraded and will be unable to drive for commercial purposes.
