Medical Examiner's Certificate (DOT Physical): Complete Guide
CFR Reference: 49 CFR 391.45 | Max Fine: $13,000
The Medical Examiner's Certificate (MEC, Form MCSA-5876), commonly called the DOT medical card, proves you are physically qualified to operate a commercial motor vehicle. An expired medical card means an out-of-service order and fines up to $13,000 for the carrier.
What It Is
The Medical Examiner's Certificate is a document issued after a DOT physical examination confirms you meet the physical qualification standards in 49 CFR 391 Subpart E. The exam evaluates vision, hearing, blood pressure, cardiovascular health, respiratory function, neurological condition, and checks for conditions that could impair safe driving. It must be performed by a medical examiner listed on the FMCSA National Registry of Certified Medical Examiners (NRCME).
Who Needs It
All CDL holders operating commercial motor vehicles in interstate commerce. This includes drivers of vehicles over 10,001 lbs GVWR, vehicles designed to transport 16+ passengers, or vehicles carrying hazardous materials requiring placards. Some state-only (intrastate) operations also require DOT physicals. Exemptions exist for certain farm vehicle drivers operating within 150 air miles of their farm.
Deadline & Frequency
The standard Medical Examiner's Certificate is valid for up to 24 months from the date of issuance. However, the examiner may issue it for a shorter period (as little as 3 months) if you have a health condition that needs closer monitoring, such as controlled hypertension or insulin-treated diabetes with a federal exemption. Your medical certificate must be on file with your state's SDLA. Start scheduling your renewal exam at least 30 days before expiration.
Step-by-Step Process
- 1
Find a certified medical examiner
Use the FMCSA National Registry search tool to find an NRCME-listed examiner near you. Only examiners on this registry can issue valid Medical Examiner's Certificates. Many urgent care clinics, occupational health centers, and chiropractors are certified.
- 2
Prepare for the exam
Bring your current glasses or contacts if you use them, a list of current medications, any specialist clearance letters (for conditions like sleep apnea, diabetes, or heart conditions), and your current medical certificate. If you have a CPAP for sleep apnea, bring your compliance report showing at least 4 hours of use per night for 70% of nights.
- 3
Complete the health history form
You will fill out the MCSA-5875 form (Medical Examination Report) before the physical. Answer honestly about your medical history. Misrepresenting your health can lead to certificate revocation, CDL disqualification, and federal penalties.
- 4
Pass the physical examination
The examiner tests: distant visual acuity of at least 20/40 in each eye, ability to perceive a forced whisper at 5 feet, blood pressure (must be below 140/90 for a 2-year certificate), urinalysis for underlying conditions, and a general physical assessment covering the spine, limbs, heart, lungs, and neurological function.
- 5
File the certificate with your state
The examiner transmits your results to the FMCSA, which shares them with your state's SDLA. Confirm with your state DMV that your medical status is updated. If there is a delay, keep a copy of your physical card in the vehicle until it is reflected in the system.
- 6
Update your Driver Qualification File
Provide a copy of the new Medical Examiner's Certificate to your carrier (or file it yourself if you are an owner-operator). The DQ file must contain the current certificate at all times.
Consequences of Non-Compliance
- The driver is immediately placed out-of-service and cannot operate any CMV.
- The carrier faces fines up to $13,000 per violation for allowing an unqualified driver to operate.
- Your CDL may be downgraded to a non-commercial license by your state if the medical certificate lapses.
- Restoring CDL status after a medical lapse requires a new DOT physical and possibly a visit to the DMV.
- Insurance coverage may be voided if you are involved in an accident while operating without a valid medical certificate.
Frequently Asked Questions
- How much does a DOT physical cost?
- A standard DOT physical typically costs $75 to $150, depending on the provider and location. Additional testing (such as a sleep study or specialist referral) can increase costs significantly. Most commercial auto insurance does not cover the exam. Some employer-sponsored health plans do.
- What blood pressure is too high for a DOT physical?
- Stage 1: If your BP is 140-159/90-99, you can receive a one-year certificate. Stage 2: BP of 160-179/100-109 gets a one-time 3-month certificate to get it under control. Stage 3: BP of 180+/110+ is an automatic disqualification until controlled. Below 140/90 qualifies for the full 2-year certificate.
- Can I get a DOT physical with sleep apnea?
- Yes, but you must demonstrate compliance with treatment. If using a CPAP machine, you need a compliance download showing at least 4 hours of use per night on 70% of nights over the prior 30 days. The examiner may issue a 1-year certificate instead of 2 years and require annual follow-up.
- What drugs does the DOT physical test for?
- The DOT physical includes a urinalysis, but this is not a drug test. It screens for underlying medical conditions like diabetes (glucose) and kidney problems (protein). The separate DOT drug test (required for pre-employment and random testing) screens for marijuana, cocaine, opiates, amphetamines, and PCP.
- Can I use my VA doctor for a DOT physical?
- Only if your VA doctor is listed on the FMCSA National Registry of Certified Medical Examiners. Many VA physicians are not registered. Check the NRCME registry before scheduling. If your VA doctor is not listed, any other NRCME-registered provider can perform the exam.
