Medical card complete,now what?

I don't know what the "official signature" is. The medical card has a place for the doctor to sign and also a place for the driver. You will need to have it attached to your CDL through your state DMV. Since you don't have your location listed, here is a thread I started a couple of months ago that will explain it; http://www.thetruckersreport.com/tr...ce/234427-did-you-have-your-medical-card.html
You should keep the long form with your records at home. all companies will require a copy of the long form. I never give the original long form, but copy it and give them that. If they want an original, they can pay for the physical, as I see it. Most companies will pay for you to get a physical so they get the original, and you just get the card.
Hope this helps.

 

If you have no CDL, then why do you need a physical, unless you're going to a school. Don't see the need for it.

 

Then you just need to carry the card. I've never had DOT ask for the long form. They have no legal reason to ask for it, unless their auditing you at which case they will come to your place of business, where you have it filed.
