Medical certification requirements as part of the commercial driver license (CDL)
Starting Jan. 30, 2012, the Iowa Department of Transportation (DOT) will implement new federal regulations requiring all CDL holders and applicants to certify the type of driving they do, and require interstate CDL holders that carry a Medical Examiner’s Certificate to give the Iowa DOT a copy of their Medical Examiner’s Certificate.
These new regulations DO NOT change who has to obtain a CDL and DO NOT change who has to obtain a Medical Examiner’s Certificate. They only require two things:
- All CDL holders and all CDL applicants must self-certify the type of driving they are engaged in. Determine what category to self-certify in.
- 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.
When do I need to comply?
All CDL holders must complete the self-certification and provide the Medical Examiner’s Certificate, if required, by Jan. 30, 2014. If you renew or change your CDL before Jan. 30, 2014, you will be required to comply at the time of the renewal or change.
If you do not renew or change your CDL before Jan. 30, 2014, you will need to complete the self-certification and submit the Medical Examiner’s Certificate on or before that date, even though your CDL does not expire until later. If you are a current Iowa CDL holder, you may submit a self-certification by utilizing the following website: https://mymvd.iowadot.gov/Account/Login. The website will provide further information on submitting your Medical Examiner’s Certificate.
What happens if I don’t comply?
The federal regulations require the Iowa DOT to downgrade your CDL to a noncommercial license if you do not complete the self-certification of the type of driving you will be engaged in and submit the Medical Examiner’s Certificate, if required, before Jan. 30, 2014.
How to self-certify and submit a Medical Examiner's Certificate
Intrastate drivers transport loads only within the state of Iowa. Their loads originate and terminate in Iowa.
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.
Determine what category to self-certify in

The federal rule requires all CDL holders make a revised self-certification prior to Jan. 30, 2014. Drivers whose CDL expiration dates extend beyond Jan. 30, 2014, should take steps to present their self-certification and, if necessary, Medical Examiner Certificate to the Iowa DOT before this date. They may present their self-certifications as listed above.
How to stay in compliance
Drivers that are required to submit a Medical Examiner’s Certificate must submit a new Medical Examiner’s Certificate before the previous one expires to stay in compliance and avoid a downgrade of their CDL to a non-commercial license. Once you have completed the initial self-certification and submitted your Medical Examiner’s Certificate for the first time, you can submit new Medical Examiner’s Certificates by:- Mailing the certificate to:
- Faxing the certificate to the Office of Driver Services at
515-239-1837. - E-mailing a scanned copy of the certificate to the Iowa DOT at CDLMedCert@dot.iowa.gov (e-mail submissions must be scanned and attached as a .pdf.)
- Presenting the certificate in person at any Iowa DL station or participating treasurer’s office.
