To qualify for a commercial driver license (CDL) you must undergo a Department of Transportation (DOT) medical examination performed in accordance with CFR 49 §391.41 and CFR 49 §391.43.
DOT medical examinations are conducted by a licensed medical examiner as defined in CFR 49 §390.5. This includes but is not limited to:
- Doctors of Medicine (MD);
- Doctors of Osteopathy (DO);
- Doctors of Naturopathic Medicine (ND);
- Advanced Practice Nurses (APN);
- Physician Assistants (PA); and
- Doctors of Chiropractic (DC).
To find a medical examiner, you may contact your primary care provider to inquire if they will conduct a "DOT medical exam". You may also find a medical examiner in the yellow pages of your telephone book, or on the internet by using an Internet directory or search engine.
After May 20, 2014, you may only use examiners listed on the National Registry of Certified Medical Examiners. Consult https://nationalregistry.fmcsa.dot/NRPublic to find certified examiners in your area.
The examiner will provide you with a medical examiners certificate that you must carry with you whenever you operate a commercial motor vehicle (CMV). In addition, you must submit a copy to DMV before original issuance of a CDL or CDL instruction permit. The copy you send to DMV must be complete and legible. If it is not, ask your examiner to complete one that is before you leave the examiner's office. To retain your commercial driving privileges, you must then send a copy of a new medical certificate to DMV before the previous certificate expires.
You’ll need to carry a valid medical certificate, even if you don’t have a CDL, if you operate a CMV in interstate commerce or operate a CMV for hire in intrastate commerce that:
- Has a gross vehicle rating in excess of 10,000 pounds; or
- Is designed or used to transport more than 8 passengers, including the driver, for compensation.
