Who needs a DOT physical exam and how often?

Drivers who operate commercial motor vehicles (CMVs) requiring a CDL—or drivers paid to carry passengers—must complete a DOT physical. Typically the certificate is valid for up to 24 months; drivers with certain conditions may require more frequent exams (e.g., annually).

What tests and checks are performed during a DOT physical?

Examinations usually include vision and hearing tests, blood pressure and pulse, urinalysis (for sugar/protein), heart and lung auscultation, neurological and musculoskeletal assessments, hernia check, and review of medical history and current medications.

How should I prepare for a DOT physical?

Bring glasses or hearing aids, recent lab results, a list of prescriptions (with dosages), written notes from treating physicians for chronic conditions, and any medical documents related to heart disease, diabetes, or other health issues.

What can cause disqualification from a DOT physical?

Conditions that may disqualify a driver include uncontrolled high blood pressure, poorly controlled diabetes, untreated sleep apnea, certain cardiovascular conditions, seizure disorders without proper exemption, or substance use that impairs safe driving. Disqualification can be temporary or permanent depending on condition and treatment.

What happens if I fail the DOT physical?

If a driver is disqualified, FMCSA may review records; disqualification may be temporary, and drivers often can reapply after treatment or corrective measures. Some cases allow appeal or re-evaluation; timelines depend on the underlying condition and FMCSA guidance.

Yes—goMDnow coordinates DOT-compliant exams at certified centers and assists clients with required forms, documentation, and guidance throughout the DOT exam process.

Are DOT physicals the same as commercial driver medical cards?

A successful DOT physical leads to the issuance of a medical examiner's certificate (medical card) indicating the driver is qualified to operate CMVs. The examiner documents the certification on the FMCSA Medical Examination Report (MCSA-5875).

DOT Physical Exam (FMCSA) for CDL Drivers

A DOT physical exam is a medical evaluation required for many commercial drivers to obtain or maintain DOT medical certification. The exam follows FMCSA medical standards and is performed by a certified medical examiner.

What is a DOT Physical?

The DOT physical helps confirm a driver can safely operate a commercial motor vehicle. During the appointment, the medical examiner reviews your health history, checks key body systems, and determines whether you meet DOT medical standards.

Most drivers who qualify are issued a medical certificate valid for up to 24 months, but the examiner may certify for a shorter period based on medical findings.

What’s Included in a DOT Physical Exam?

A DOT physical typically includes: vision and hearing checks, vital signs (blood pressure and pulse), a urinalysis screening, and a head-to-toe physical exam. The examiner will also review your medical history, current medications, and any recent specialist notes if applicable.

The exam may include additional documentation requests (for example, recent reports for certain conditions) when needed to support a safe and accurate certification decision.

Why Do CDL Drivers Need a DOT Physical?

DOT medical certification is designed to reduce preventable risk by ensuring drivers meet medical standards that support safe driving. If the examiner identifies an issue that needs monitoring, they may issue a shorter certification interval and request follow-up documentation at the next exam.

Who Needs DOT Medical Certification?

In general, DOT medical certification applies to commercial drivers operating in interstate commerce when the vehicle meets FMCSA CMV criteria (for example: vehicles over 10,000 lbs GVWR/GCWR, certain passenger-carrying operations, or hazardous materials transport).

What to Bring to Your DOT Physical

To help your visit go smoothly, bring the items below (only where applicable):

A valid government-issued ID
Glasses or contacts (if you use them for driving)
A list of current medications (name + dose)
Relevant medical records or clearance letters (if you have an ongoing condition)
Any required forms from your employer (if provided)

What Happens If You’re Not Medically Qualified?

If you are found not medically qualified, the qualification decision is made by the medical examiner. You can discuss the reason for the determination with the examiner and provide additional medical documentation if relevant.

In some cases, drivers may also pursue condition-specific FMCSA pathways (such as exemptions) where applicable.
