Commercial vehicles/CDL

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 Certificate

CDL 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.

The FMCSA announced a 120-day grace period during which Medical Examiners may use either the current or the newly revised versions of the Medical Examination Report (MER) Form and Medical Examiner’s Certificate (MEC). This period is from December 22, 2015, until April 20, 2016. This action is being taken to ensure that Medical Examiners have sufficient time to become familiar with the new forms and to program electronic medical records systems.

Intrastate drivers

Beginning 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).

If a CDL holder is not in compliance, federal regulations require the Iowa DOT to downgrade their CDL to a noncommercial license. It is important for CDL holders certified as “nonexcepted interstate” to track the expiration date of their Medical Examiner’s Certificate and provide the Iowa DOT with a copy of their new certificate when it is renewed.

This rule making action helps to prevent medically unqualified drivers from operating on the nation's highways by providing states’ licensing agencies a means of identifying interstate CDL holders who are unable to obtain a Medical Examiner’s Certificate and taking action to downgrade their CDLs accordingly.

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.

Whenever a CDL is issued, a driver’s license examiner will ask the CDL driver to self-certify to the category designation that applies to him or her. The first step is to determine if he/she is an interstate or intrastate driver. If someone is new to the transportation industry, that person should decide which category they expect to be engaged in. This step is important because it affects the self-certification.

The driver must select which one of the four categories applies to them. The categories are:

Determine which category applies to me

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.

Submitting renewed medical certificates

Drivers that are required to submit a Medical Examiner’s Certificate must provide a new Medical Examiner’s Certificate to the Iowa DOT before the previous one expires to stay in compliance and avoid a downgrade of their CDL to a noncommercial license. Renewed Medical Examiner’s Certificates can be submitted to the Iowa DOT in the following ways.

• Mailing the certificate to:
  Iowa Department of Transportation
  Driver & Identification Services
  P.O. Box 9204
  Des Moines, IA 50306-9204

• Faxing the certificate to Driver & Identification Services at: 515-239-1837.
• Emailing a scanned copy of the certificate to the Iowa DOT at CDLMedCert@iowadot.us. (email submissions must be scanned and attached as a .pdf file).
• Presenting the certificate in person at any Iowa driver’s license issuance site.
