Can commercial drivers obtain a second opinion on a DOT medical exam?
Motor carriers — whether they employ a handful of commercial drivers or thousands — often face an important question: If a driver is disqualified during a Department of Transportation (DOT) medical exam, is the driver allowed to seek a second opinion? For motor carriers, this situation can create uncertainty and raise concerns about compliance, safety, and legal risk.
FMCSA’s guidance on second opinions
According to the Federal Motor Carrier Safety Administration (FMCSA) guidance, a driver who receives a disqualified status may seek a second opinion from another National Registry Certified Medical Examiner.
However, the process has important requirements:
- Drivers should obtain permission from their motor carrier before scheduling a second exam. Carrier that allow drivers to seek a second opinion may choose which Certified Medical Examiner drivers visit.
- Carriers should maintain a list of approved medical vendors to ensure consistent and reliable examinations. Understanding these rules helps carriers manage risk and maintain compliance.
- Carriers, however, should also watch out for these four areas of compliance that, if not followed, could steer them off course when it comes to driver medical exams.
Four watch-outs for motor carriers
1. Drivers must provide the same health information to every examiner
Drivers are required to give complete and truthful medical information at each exam. If a driver withholds or changes information to obtain a medical certificate from a second examiner, it can create serious problems:
- Drivers can face civil penalties.
- Motor carriers may also be liable if the driver is involved in a crash and was certified based on incomplete or inaccurate information.
- Motor carriers could inadvertently place a medically unfit driver behind the wheel of a commercial motor vehicle .
- Let’s say a driver previously reported severe fatigue that raised concerns about possible sleep apnea. That information must be shared with any second examiner. Withholding it in hopes of receiving a 2-year medical card creates significant compliance, legal, and safety risks to both the driver and motor carrier.
2. Carriers aren’t required to review the 'long form' medical report
Motor carriers aren’t required to obtain or review the driver’s DOT Medical Examination Report Form MCSA-5875 (long form). Without this information, it may be difficult for carriers to determine whether the driver disclosed accurate medical history during a second exam.
Carriers that choose to collect or review long form medical information must:
- Obtain written consent from the driver.
- Work closely with HR to ensure a consistent and compliant policy.
- Use clear procedures for authorizing and storing medical information.
3. The FMCSA receives all exam results
All DOT medical exam results are submitted to the FMCSA National Registry. This means:
- A disqualified exam will appear in the driver’s National Registry record.
- If the driver quickly receives a second exam that results in a valid certification, the FMCSA may choose to review the situation more closely.
4. Carriers should watch for ‘doctor shopping’
Motor carriers should be alert for patterns that may indicate drivers are "doctor shopping.” Drivers who repeatedly seek new examiners that will overlook medical concerns pose risks for carriers. The FMCSA frowns upon “doctor shopping” because it undermines the integrity of the medical certification process. Carriers that allow drivers to do this will certainly raise red flags with the FMCSA if multiple exams occur within a short time frame.
Key to remember: Allowing a second opinion can be appropriate when handled correctly, but it must be managed carefully. Carriers should communicate clear guidelines to drivers, understand the FMCSA requirements, and maintain strong internal policies to protect both the company and the public.
