Not so much any more. It all depends on the ethics of the Dr. Gubment is putting pressure on them. They can be sued if driver they issued med card to has a wreck.
Used to be able to pick up a blank med card in the truck stops, fill it out, scribble a signature and that was good enough. Cops never even asked for it until the last few years.
Now we have to have the long form with the Dr address and phone #. My Dr told me his staff must drop everything if officer calls to verify authenticity.
Rumor has it Dr must get registered with FMCSA and as drivers we would have to use one of those Docs.
Sounds like they are trying to clean up the abuse.
