So what exactly does the CDL medical entail? With a complicated medical case, is it somewhat easier to pass than the 3rd class medical? Or is it just about the same as 3rd class?
I downgraded my CDL a few years ago because I wasn't using it anymore, and the process of getting it renewed was just too time-consuming and expensive to bother with. But here's how it worked when I had one.
The physical itself is just a basic, but fairly thorough physical. Most drivers get the physicals from their PCPs or from "company doctors" contracted by their carriers. The examinations can be administered by anyone whose state professional license allows them to perform physical examinations, unless they have been specifically disqualified.
As for the requirements, some conditions are always disqualifying, and a very few require federal waivers (for example, my DM2 waiver). The rest are judgment calls, meaning that the examiner can issue a certificate to a less-than-perfect specimen of a human being if he or she is convinced that whatever conditions they may have are adequately controlled.
One
big difference from the FAA medical is that the word
current can be found throughout the
requirements. The driver cannot have a
current diagnosis of blah blah blah. No one cares very much if the driver had an ADD diagnosis when he or she was 6 years old, or suffered from PTSD after returning home from Vietnam. What matters is the driver's
current condition. And again, even a
current diagnosis of blah blah blah may not be disqualifying if it's adequately controlled.
Another big difference from the FAA medical is that the examiner can simply issue a certificate if a condition has been corrected, without (literally) making it a federal case. For example, a driver who had a cardiovascular condition that has been surgically corrected can be issued in-office. Same goes for cataract removal and so forth. The driver
had a condition. Once it's been corrected, it's no longer current, and the driver is qualified. No federal imprimatur is required.
In summary, the examiner is expected to use his or her clinical skills, consideration of the driver's history, consultation with the driver's personal physician, and common sense, to make a decision as to the driver's fitness at the time of the physical and for the duration of the certificate's validity.
The examiner does have the option of limiting the duration in the case of chronic condition that require monitoring, such as high blood pressure, diabetes (if the driver also has a waiver), and so forth.
Other than in those very few cases that require federal waivers, the federal government's involvement is limited to issuing the
form -- and they don't want it back. Once the form is completed, it's given to either the driver or the driver's employer, or both. The only part the driver needs to carry or present to the DMV or a police officer is the "card" the examiner fills out (actually a folded-up piece of paper), and any waiver(s) he or she has been issued.
Like I said, that was the way it worked the last time I renewed my CDL. I don't have any reason to believe that it's changed since then.
If I had to make one suggestion to improve the process, it would be that I believe the only examiners who should be allowed to issue should be the driver's PCP or the "company doctor." As with FAA medicals, there are "pencil whippers" who will issue to anyone who has a pulse and who isn't so blind that they can't find the examiner's office. These examiners' business cards can be found on bulletin boards at truck stops. So yeah, there is some doctor-shopping that goes on.
