A Two-Year Card From a Provider Who Is Not on the National Registry
JC is a 57-year-old interstate driver applying for a new certificate. He hands you a Medical Examiner's Certificate issued 20 months ago for a two-year period by a chiropractor; it is the only document his carrier has on file. He says the visit was quick, that no urine specimen was collected, and that he was told his blood pressure was "fine." He takes lisinopril for hypertension; today's BP is 138/86 on two readings, and the rest of his examination is unremarkable. During the visit he asks whether you, a nurse practitioner, are "allowed to sign the DOT card," and whether you can give him a two-year card because his pressure is controlled and his company is short of drivers. A check of the National Registry shows the chiropractor is not listed.
1. Is the existing certificate valid, and what do you do with the information about the previous examiner?
Read the worked answer
The certificate does not meet the requirements.
- A valid examination must be performed by a medical examiner who is licensed, has the requisite training, and is listed on the National Registry of Certified Medical Examiners; the certificate must carry the examiner's registry number. A certificate signed by a provider who is not on the registry does not satisfy 49 CFR 391.43, no matter how long the carrier has accepted it. Employer acceptance never cures a defective certificate.
- The examination he describes is also facially incomplete - the required components, including the urinalysis portion, must actually be performed and documented.
- What you do: perform and document a complete examination yourself. Record the history of the prior certificate factually in the examination report. Explain to the driver that his prior card is not valid documentation and that he should tell his carrier. Do not diagnose or attack the other provider in the record, and do not alter or reissue anyone else's certificate.
- If you believe an unregistered person is routinely issuing certificates, you may raise it with FMCSA as a program-integrity concern, but that is separate from this driver's certification decision.
2. Can you, as a nurse practitioner, perform and sign this examination? What conditions apply?
Read the worked answer
Yes, if all three conditions are satisfied.
- Licensure and state scope: you must be licensed in the state where you practice and the examination must fall within your scope of practice. Scope rules vary by state; some states impose supervision or collaborative-agreement requirements, and those apply to DOT examinations too.
- Registry status: you must be currently listed on the National Registry of Certified Medical Examiners and must include your registry number on the certificate. Registry status is personal - it does not extend to a supervising physician or to the practice.
- Exam integrity: you must personally conduct the examination elements required by 49 CFR 391.43, know the physical qualification standards in 391.41, and hold the certification decision yourself. You cannot sign off on an examination performed by unqualified staff or on a records review alone.
If any element is missing - for example, your registry certification lapsed - you must not perform the examination until it is restored, and the driver should be referred to a qualified examiner rather than rescheduled informally.
3. What certificate duration is appropriate for this driver, and how do you answer his request for two years?
Read the worked answer
Two years is the ceiling, not the default.
- The maximum certification period for a qualified driver is two years, but shorter intervals are used whenever a condition warrants monitoring. Driver convenience and carrier staffing have no bearing on the duration.
- This driver has treated hypertension with a BP of 138/86. Under the FMCSA hypertension guidance, a driver with hypertension on treatment is generally certified on a one-year cycle, even when readings are at goal, because the certification depends on continued control.
- Explain the reasoning to the driver: the length of the card tracks the stability of the condition being monitored, not the examiner's confidence in him. If he later comes off medication and sustains normal pressures off treatment, a longer interval could be considered - but only with documented readings.
- Document the blood pressure readings (arm, position, repeat), the treatment history, and the rationale for the one-year interval in the examination report, then complete the certificate with the correct expiration date.
