A 3-month DOT medical card usually means 1 of 2 things. Your blood pressure was in the stage 2 range, 160-179 systolic or 100-109 diastolic, so the examiner gave you a one-time certificate while treatment starts or gets adjusted. Or you are treated with insulin and do not yet have 3 months of electronic blood glucose records. For blood pressure, get to at or below 140/90 and the 1-year certification path is available from the original exam date. For insulin-treated diabetes, build the required record and complete MCSA-5870 [1][2][3].
Why did the examiner give me a 3-month card?
For blood pressure, the answer is usually stage 2. The guidance used by DOT medical examiners sets that stage at 160-179 systolic or 100-109 diastolic. The examiner can issue a one-time 3-month certificate so treatment can start or be adjusted. Once your blood pressure is at or below 140/90, you can be certified for 1 year from the date of the original exam [1].
That is not the same as a failed exam. The examiner found that you could be certified for a limited period while the condition gets addressed. Your certificate is still Form MCSA-5876, the wallet card drivers call a med card. The examination itself is recorded on MCSA-5875 [4].
The card does not mean the examiner has set a personal blood pressure target outside the guidance. It means the reading fell into a defined stage, and the certificate length followed that staging. The federal regulation says a driver must not have high blood pressure likely to interfere with safe CMV operation, but the regulation itself does not contain a numeric cutoff. The numbers come from examiner guidance [2][1].
What does the blood pressure deadline actually mean?
The clock starts with the original exam date, not the day you finally get the reading under control. The 3-month certificate is one-time for the stage 2 blood pressure path. It is not a temporary card you can keep renewing while the same readings continue [1].
The practical target is clear. Get your blood pressure to at or below 140/90, then return for the recheck the examiner requires. Under the staging guidance, that can support certification for 1 year from the original exam date. The exact certificate remains examiner judgment, because examiners can certify for less than the maximum when a condition needs monitoring [1].
Other stages have different consequences. A reading of 140-159 systolic or 90-99 diastolic supports a 1-year card under the guidance. A reading at or above 180 systolic or 110 diastolic means disqualification until blood pressure is brought under control. After control is shown, certification continues on 6-month cards [1].
Either number can place you in a stage. A lower systolic number does not cancel a diastolic number in the stage 2 range, and the reverse is also true. Bring the actual readings and treatment record to the recheck. A single better reading may not answer the examiner's questions about control.
What should I do this week after getting the card?
Start by reading the dates on your MCSA-5876. Write down the issue date and expiration date. Because your card was issued yesterday, this is the first week of the 12-week clock, whether the card lists the dates you expected or not.
Next, contact the clinician who manages your blood pressure. Bring the card, the examination paperwork, and any readings you already have. The goal is not to talk your way around the card. The goal is to address the condition that produced the short certification and create records the examiner can review.
A home cuff log can show a pattern between visits. Keep it consistent and bring the log to the recheck. Do not wait until the last week to discover that your readings are still in the same stage. If treatment was started or adjusted, keep the documentation with your other med-card paperwork.
The DOT physical includes a health history review, blood pressure and pulse, vision, hearing, a urinalysis dipstick screening specific gravity, protein, blood, and glucose, plus a hands-on exam of body systems [1]. Your blood pressure is only 1 part of the visit, but it is the part that created this particular deadline.
You can review the staging details in the DOT blood pressure limits guide and the treatment planning information in the CDL blood pressure medication guide. The broader resource is the DOT physical hub.
Could my 3-month card be for insulin-treated diabetes instead?
Yes. The other 3-month card is for an insulin-treated driver who does not yet have 3 months of electronic blood glucose self-monitoring records. Under 49 CFR 391.46, the driver can receive a certificate of up to 3 months while the record builds [3].
That path is not the same as stage 2 blood pressure. The blood pressure card is tied to reaching at or below 140/90 and the 1-year path from the original exam date. The insulin-treated diabetes card is tied to the record requirement and the diabetes assessment process.
Your treating clinician, meaning the healthcare professional who manages and prescribes insulin for your diabetes, completes and signs MCSA-5870. The medical examiner then examines you at least annually and no later than 45 days after the treating clinician signs the form [3]. An insulin-treated driver with at least 3 months of electronic blood glucose self-monitoring records can be certified for up to 12 months [3].
The qualification standards do not contain an A1C number. Do not assume that an A1C result alone replaces the required records or the MCSA-5870 process. Put the form, electronic record information, and examination paperwork together before the recheck.
If you are unsure which path produced the card, call the examining clinic and ask whether the short certificate was issued for stage 2 blood pressure or for missing insulin glucose records. The answer changes what you need to bring next.
What happens at the recheck?
The medical examiner reviews the condition that led to the short card and decides whether you meet the standard for the next certification period. The examiner who performs a DOT physical must be listed on the FMCSA National Registry of Certified Medical Examiners [4]. You, your carrier, or a clinic can verify that listing through the FMCSA National Registry search.
For the blood pressure path, bring your MCSA-5876, the original examination paperwork, the home cuff log, and documentation from the clinician managing the condition. The key question is whether your blood pressure is at or below 140/90 and whether the examiner has enough information to certify you for the next period. The 1-year period, when issued under this guidance, runs from the original exam date [1].
For the insulin-treated path, bring MCSA-5870 and the electronic blood glucose self-monitoring records. The treating clinician signs the form. The medical examiner makes the certification decision after the required examination [3].
Do not treat the recheck as a formality. A short certificate is a real certification with a real end date. If the condition has not reached the required point, the examiner may not issue the result you want. No hands-on federal exam can be gamed, and no clinic can promise a card length.
What does the 12-week plan look like?
Use this timeline to turn yesterday's card issue into a dated work plan.
| Week | Blood pressure card | Insulin-treated diabetes card |
|---|---|---|
| 1 | Read MCSA-5876, record the expiration date, and contact the clinician managing blood pressure. | Read MCSA-5876, record the expiration date, and contact the treating clinician about MCSA-5870. |
| 2 | Start or continue a home cuff log and keep the first readings with the exam paperwork. | Confirm how electronic blood glucose self-monitoring records will be collected and retained. |
| 3 | Review the log with the clinician and document any treatment decision. | Keep building the electronic record and confirm the treating clinician has the required information. |
| 5 | Check the log for readings still in the stage 2 range, 160-179 systolic or 100-109 diastolic. | Check that the electronic record is being retained and that MCSA-5870 is moving through the treating clinician's office. |
| 6 | Ask the clinician for updated documentation if treatment was started or adjusted. | Ask whether the record now covers 3 months and whether the clinician can complete MCSA-5870. |
| 8 | Compare the home log with the at or below 140/90 target used for the next certification path. | Confirm the 3-month record is available for the medical examiner to review. |
| 10 | Book or confirm the recheck with a medical examiner listed on the National Registry. | Book or confirm the recheck with a medical examiner listed on the National Registry. |
| 12 | Bring MCSA-5876, MCSA-5875, the home cuff log, and clinician records to the recheck. | Bring MCSA-5876, MCSA-5875, MCSA-5870, and the electronic glucose records to the recheck. |
The dates on your certificate control. If they do not line up with a 12-week plan, follow the expiration date printed on MCSA-5876 and contact the examining clinic.
What to do next
Written for a driver whose 3-month card was issued yesterday.
- Pull out MCSA-5876 and write down the issue date and expiration date.
- Call the examining clinic and confirm whether the card was for stage 2 blood pressure or missing insulin glucose records.
- If blood pressure caused the card, book the clinician visit and start a home cuff log.
- If insulin-treated diabetes caused the card, contact the treating clinician about MCSA-5870 and the electronic blood glucose records.
- Keep MCSA-5875, MCSA-5876, clinician notes, and readings in 1 folder.
- Verify the recheck examiner through the FMCSA National Registry search.
- Bring the complete folder to the recheck before the certificate expires.
- If the blood pressure path applies, aim for readings at or below 140/90 because the 1-year path runs from the original exam date [1].
- If the insulin path applies, bring at least 3 months of electronic blood glucose self-monitoring records when available [3].
