This is good news.

Under PennDOT's old policy, to change the gender on their licenses or state ID cards, people had to prove they had sexual reassignment surgery. The new policy that is effective immediately doesn't require proof of surgery. It does allow a change in gender on the licenses if people are living full-time in the new gender and it is verified by a licensed medical or psychological caregiver or social worker "whose practice includes helping people with gender identity issues."

Change. It does happen.  Even in Pennsylvania.
