Frequently asked questions
Commercial Driver’s License (CDL) Certification and Medical CertificateFederal regulations require all CDL holders and applicants to certify how they operate their commercial motor vehicle whenever they renew, upgrade, or obtain a CDL for the first time. A CDL holder must certify to one of four categories that apply to the type of driving they do.
Determine which category applies to me.
What do I have to do?
- All CDL holders and all CDL applicants must self-certify the type of driving they are engaged in whenever they renew, upgrade, or obtain a CDL for the first time. Determine which category applies to me.
- Drivers that certify to "nonexcepted interstate" driving must give the Iowa DOT a copy of their Medical Examiner’s Certificate, and must keep that Medical Examiner’s Certificate current.
Medical Examiner's CertificateCDL holders that certify to the “nonexcepted interstate” category must provide a copy of their Medical Examiner’s Certificate to the Iowa Department of Transportation.
Beginning May 21, 2014, a commercial driver who is renewing or obtaining a new Medical Examiner’s Certificate must be examined by a medical professional listed on the National Registry of Certified Medical Examiners. Medical certificates issued on or after this date must include the medical examiner’s national registry number. Medical certificates issued prior to this date are still valid until their expiration date. You can learn more about the national registry and search for a certified medical examiner at: https://nationalregistry.fmcsa.dot.gov.
Intrastate driversBeginning July 1, 2014, drivers who certify to intrastate driving, either excepted or nonexcepted, will have a “K” restriction placed on their license. The restriction limits the driver to intrastate driving whenever they operate a commercial motor vehicle (CMV.)
What happens if I don't comply?
Why was this implemented?
The rule also serves as a deterrent to drivers submitting falsified Medical Examiner’s Certificates because the Federal Motor Carrier Safety Administration and states’ enforcement personnel will now have access, via the Commercial Driver License Information System, to information about the Medical Examiner’s Certificate and identity of the medical examiner who performed the examination. Electronic access will enable FMCSA and states’ enforcement personnel to detect certain patterns or anomalies concerning the source of medical certificates through queries of the licensing databases at any time rather than being limited to checking for such issues during roadside inspections and compliance reviews.
How to self-certify
Intrastate drivers transport loads only within the state of Iowa. Their loads originate and terminate in Iowa. Drivers who certify in this category will have a “K” restriction placed on their license indicating intrastate driving only (when operating a commercial motor vehicle).
Nonexcepted interstate: This driver conducts interstate commerce and must have a Medical Examiner’s Certificate per federal regulation. The certificate must be placed on file with the Iowa DOT under the new regulations.
Excepted interstate: This driver conducts interstate commerce, but is involved in one of the several transportation activities that have a federal exception from the medical requirements (49 CFR parts 390.3(f), 391.2, 391.68 and 398.3).
Nonexcepted intrastate: This driver conducts intrastate commerce within the state of Iowa and must have a Medical Examiner’s Certificate per Iowa Code 321.449 and 321.450. The certificate does not have to be on file with the Iowa DOT.
Excepted intrastate: This driver operates within the state of Iowa, but is excepted from medical requirements per Iowa Code 321.449 and 321.450.
How to submit a medical certificate if required
If the driver self-certifies as nonexcepted interstate, he/she must provide a copy of his/her Medical Examiner’s Certificate to the driver’s license examiner at the time the driver applies for a CDL. Beginning May 21, 2014, commercial drivers renewing or obtaining a new Medical Examiner’s Certificate must be examined by a medical professional listed on the National Registry of Certified Medical Examiners. Information on the certificate, including the medical examiner’s national registry identification number, will be entered onto the official driver’s record and its expiration date will be tracked. It is the responsibility of the driver to keep the Medical Examiner‘s Certificate current and provide updated copies to the Iowa DOT.Find a Certified Medical Examiner on the National Registry of Certified Medical Examiners

Renewed Medical Examiner’s Certificates can be submitted to the Iowa DOT in the following ways.
- Mailing the certificate to:
Iowa Department of Transportation
Office of Driver Services
P.O. Box 9204
Des Moines, IA 50306-9204
- Faxing the certificate to the Office of Driver Services at: 515-239-1837.
- Emailing a scanned copy of the certificate to the Iowa DOT at CDLMedCert@dot.iowa.gov (email submissions must be scanned and attached as a .pdf file).
