No. Your regular family doctor cannot perform a DOT physical unless they happen to hold a specific federal certification. Under federal rules, only a healthcare professional who is certified by the Federal Motor Carrier Safety Administration and listed on the National Registry of Certified Medical Examiners can conduct the exam and issue a valid medical certificate for an interstate commercial motor vehicle driver.1eCFR. 49 CFR 390.5 An exam performed by anyone else, no matter how qualified in general medicine, doesn’t count.
Who Is Actually Allowed to Perform the Exam
Federal regulations start with state licensure. The provider must be licensed under their state’s laws to perform physical examinations. Within that group, FMCSA specifically recognizes doctors of medicine (MDs), doctors of osteopathy (DOs), doctors of chiropractic (DCs), physician assistants, advanced practice nurses, and certain other medical professionals authorized by their state to conduct physicals.2Federal Motor Carrier Safety Administration.

Holding one of those licenses is only the entry ticket. To actually perform DOT physicals, the provider then has to:
- Complete FMCSA-approved training on the federal physical qualification standards for commercial drivers.
- Pass the National Registry certification exam.
- Have their medical license validated by FMCSA and be listed on the National Registry.3Federal Motor Carrier Safety Administration. National Registry of Certified Medical Examiners
Certification isn’t permanent either. FMCSA requires refresher training between four and five years after initial certification, a second refresher between nine and ten years, and a full recertification test at the ten-year mark.4Federal Motor Carrier Safety Administration. 10-Year Refresher Training and Recertification Testing Requirements An examiner who falls behind loses their listing, and any physical they perform once they’re off the registry produces a certificate that isn’t valid.
The practical takeaway: even if your primary care doctor is an MD in good standing, the answer is still no unless their name appears on the National Registry with a current status. Some family practices and urgent care clinics do have certified examiners on staff. Many do not. You have to check before you book.
How to Confirm a Provider Is Certified
FMCSA runs a public lookup tool on the National Registry website. You can search for certified examiners by zip code, city, or state.5FMCSA National Registry. Search Medical Examiners An advanced search lets you pull up a specific examiner by name or by their National Registry number if you already have it.3Federal Motor Carrier Safety Administration.

Two things to verify before you show up:
- The examiner’s listing is current, not expired or suspended.
- The clinic you’re booking with is the one that examiner actually works at. Registry entries are tied to the individual provider, not the practice.
If you can’t find a provider on the registry, they can’t legally perform your DOT physical, regardless of what their office tells you over the phone. This is worth confirming yourself rather than taking the receptionist’s word for it.
Cost typically runs between $75 and $200 depending on location and provider. If your employer requires the physical, the motor carrier usually pays. Owner-operators and independent drivers generally pay out of pocket, and insurance rarely covers the exam because it’s treated as an occupational requirement rather than a diagnostic visit.
Interstate Versus Intrastate Driving
The National Registry requirement is a federal rule, and it applies to drivers operating commercial motor vehicles in interstate commerce. If you drive only within a single state, your state sets its own medical certification rules.6Federal Motor Carrier Safety Administration. How Do I Determine Which of the 4 Categories of Commercial Motor Vehicle Operation I Should Self-Certify
Some states have adopted the federal standards wholesale, which means intrastate drivers there still need a certified medical examiner. Other states have their own requirements, and some exempt certain intrastate drivers from medical certification entirely. If you’re not sure which category you fall into, your state driver licensing agency can tell you which rules apply. Don’t assume the federal answer covers your situation without checking.
What Happens If a Non-Certified Provider Signs the Form
A DOT physical performed by a provider who isn’t on the National Registry doesn’t produce a valid Medical Examiner’s Certificate. That has real consequences.
For CDL holders, the medical certificate has to be submitted to the state driver licensing agency before the previous one expires. If the certificate on file isn’t valid, or if you fail to update the state’s records at all, your commercial driving privileges are downgraded to a regular license. You cannot operate a commercial vehicle again until the issue is fixed.7Federal Motor Carrier Safety Administration. Medical That means booking a new exam with a properly certified examiner and going through the process again, on your own time and often at your own expense.
The valid certificate itself, when issued by a certified examiner, is form MCSA-5876, sometimes called a “medical card,” and it lasts up to 24 months.8Federal Motor Carrier Safety Administration. DOT Medical Exam and Commercial Motor Vehicle Certification An examiner can issue a shorter certificate when a condition needs monitoring. Whichever version you get, it’s only valid if the person who signed it is on the registry on the day they signed it.
Before scheduling any DOT physical, do the thirty seconds of verification. Look the provider up on the National Registry. Confirm the certification is active. If it is, you’re clear to book. If it isn’t, keep looking. Any other approach risks paying for an exam that won’t hold up when your state or your employer looks at the paperwork.
