I'm an RN and I can assure you that when someone comes in, we do NOT look at drivers licenses to see if they want to be an organ donor. That's just to let your family know that you'd like to do that if they didn't know. So make sure and communicate your wishes to your family. Because if they say NO, we can't use your organs, even if you said YES on your drivers license. It is up to the next of kin to make that decision. Doesn't seem like they should have that power to veto your decision to donate your organs, but they do.
"Having heard all of this, you may choose to look the other way.....
but you can never say again that you did not know." William Wilberforce 1759-1833
