Medical Certificate in the DQ File — What Carriers Must Keep
A copy of each driver's current medical certificate must be in their DQ file. This page explains the specific documentation requirements and how to handle certificate updates.
What must be in the DQ file
The carrier must maintain a copy of the driver's medical examiner's certificate (MCSA-5876) in the DQ file. The certificate must be current — not expired. The copy should show the driver's name, the certificate number, the expiration date, and the examiner's information.
Updating the file when a new certificate is issued
When a driver obtains a new DOT physical and is issued a new medical certificate, provide a copy to the carrier promptly. The carrier should update the DQ file and revise the expiration date in any tracking system. The prior certificate can be retained per the general retention schedule — it does not need to be destroyed.
What the certificate must show
The medical examiner's certificate (MCSA-5876) must show the driver's name, the National Registry number of the certifying examiner, the date of the exam, the expiration date, and any restrictions the examiner imposed. A certificate that lacks the examiner's NPI or National Registry number is not valid — it must have been issued by an examiner on the FMCSA National Registry. Verify this when you first receive the certificate from a new driver.
Tracking expiration dates across multiple drivers
Medical certificate expiration dates are staggered across all drivers, and they do not follow a calendar year schedule. A standard 24-month certificate expires on a date 24 months from the exam — a driver whose exam was in March expires in March two years later. A driver with a shorter certification period (common for blood pressure or cardiovascular conditions) may have a 12-month, 6-month, or shorter card. Maintain a simple log or spreadsheet with each driver's name and certificate expiration date, reviewed monthly.
What an expired certificate means for the carrier
If a driver operates a CMV with an expired medical certificate, the carrier has permitted an unqualified driver to operate. This creates a CSA violation under the Driver Fitness BASIC and can appear as a driver out-of-service finding at a roadside inspection. In a compliance review, a DQ file with an expired medical certificate on file is a cited deficiency. The consequences extend beyond inconvenience — a pattern of expired medical certificates indicates a failure of the carrier's compliance management process.
When a driver gets a new certificate but doesn't hand it in
This is more common than it should be. A driver renews their DOT physical, gets a new two-year certificate, puts it in their wallet — and doesn't think to give the carrier a copy. Months later, the carrier's file still shows the old certificate, which may now be expired even though the driver's physical is actually current. The fix is a clear policy: require drivers to submit a copy of any new medical certificate within a set number of days of the exam and track submissions against expiration dates. If you don't have a process for this, drivers who stay current on physicals can still leave you with a DQ file deficiency through simple inattention.
Certificates with restrictions — what carriers need to know
Some medical examiners issue certificates with conditions or restrictions — requiring vision correction, hearing aids, or a shorter certification period. These conditions appear on the certificate itself and are relevant to the carrier's compliance obligations. A driver whose certificate requires corrective lenses must be wearing them when operating. A carrier whose DQ file contains a restricted certificate is on notice of those conditions. If a driver is later involved in an accident and was operating without required corrective lenses, the carrier's knowledge of the restriction — documented in the DQ file — is part of the record.
Frequently Asked Questions
Does the carrier need the original medical certificate or a copy?
A copy is acceptable for the DQ file. The driver must carry the original (or a state-issued documentation of the certification) when operating a CMV. The carrier retains a copy; the driver carries the original.
What if a driver's medical certificate expires and they haven't scheduled a new physical yet?
Remove the driver from CMV operation until a new certificate is issued. An expired certificate is a disqualifying condition under Part 391. The driver cannot operate while unqualified, regardless of how long they've been with the fleet or how close they are to scheduling the exam.
Does the carrier need to verify that the medical examiner is on the FMCSA National Registry?
Best practice is yes. The medical examiner's National Registry number appears on the MCSA-5876. Look it up at nationalregistry.fmcsa.dot.gov to confirm the examiner was listed at the time of the exam. A certificate issued by an unlisted examiner is not a valid DOT medical certificate even if it looks authentic. Verifying this on day one prevents a DQ file deficiency that may surface months later.
A driver's medical certificate shows restrictions — what does the carrier need to do?
Document the restrictions in your records and ensure the driver complies with them while operating. For example, if the certificate requires corrective lenses, the driver must wear them during CMV operation. The carrier is on notice of those conditions once the certificate is in the DQ file. If a driver later operates in violation of their certificate restrictions and an incident occurs, the carrier's documented awareness of the restrictions is part of the record.
